Reducing a files size with high quality

is there a way to reduce a file size from about 60M to about 500k and keeping the quality? dpi is 300

If you are looking to "find how many pixels it has in each dimension", you'd look under "190M".
Your task to reduce to 500kb is impossible. No image that large belongs on a webpage.
If you reduce the width to roughly 1000 pixels and find that the text is unreadable, then you did not design the web page graphic properly. Start over on a document already sized for the web page. When designing web graphics, you should most always be looking at a 100% zoom view. Note the zoom percentage displayed in the image tab or image window title bar. Keep it at 100%.

I have a .mov file that is 59 gigs. Is there a converter that can reduce the file size with minor resolution loss so I can import it into final cut express?

I have a .mov file that is 59 gigs. Is there a converter that can reduce the file size with minor resolution loss so I can import it into final cut express?

Open the file in QuickTime Player. Then do Tools > Show Movie Inspector. What does it say for Format and FPS?
At 59GB, I suspect you have either a 4 hour DV video or a 1+ hour video that was converted to Apple Intermediate Codec. If it's either of those, you can import it directly into FCE provided you select the appropriate Easy Setup first. Your clips have to match the properties of the Easy Setup you are using.
If it's neither DV or AIC then you need to convert it to one of those codecs. (QuickTime/DV or QuickTime/AIC) Many people in this forum rely on MPEG Streamclip (it's free and works great).

I've reduced my project size to "high quality," with a resulting 2.42GB size and 78 minutes project time. With my 4.7GB dvd, I should now have more than sufficient space, but I still get 'Your project exceeds the maximum content duration."

Am I simply out of luck? The video itself is 65 minutes with pretty simple music and photos in the themes with no scene selection option.
Thanks.

iDVD is not concerned with size, just length.
iDVD encoding settings:
http://support.apple.com/kb/HT1502?viewlocale=en_US
Short version:
Best Performance is for videos of up to 60 minutes
Best Quality is for videos of up to 120 minutes
Professional Quality is also for up to 120 minutes but even higher quality (and takes much longer)
That was for single-layer DVDs. Double these numbers for dual-layer DVDs.
Professional Quality: The Professional Quality option uses advanced two-pass technology to encode your video (The first pass determines which parts of the movie can be given greater compresson without quality loss and which parts can’t. The second pass then encodes those different parts accordingly) , resulting in the best quality of video possible on your burned DVD. You can select this option regardless of your project’s duration (up to 2 hours of video for a single-layer disc and 4 hours for a double-layer disc). Because Professional Quality encoding is time-consuming (requiring about twice as much time to encode a project as the High Quality option, for example) choose it only if you are not concerned about the time taken.
In both cases the maximum length includes titles, transitions and effects etc. Allow about 15 minutes for these.
You can use the amount of video in your project as a rough determination of which method to choose. If your project has an hour or less of video (for a single-layer disc), choose Best Performance. If it has between 1 and 2 hours of video (for a single-layer disc), choose High Quality. If you want the best possible encoding quality for projects that are up to 2 hours (for a single-layer disc), choose Professional Quality. This option takes about twice as long as the High Quality option, so select it only if time is not an issue for you.
Use the Capacity meter in the Project Info window (choose Project > Project Info) to determine how many minutes of video your project contains.
NOTE: With the Best Performance setting, you can turn background encoding off by choosing Advanced > “Encode in Background.” The checkmark is removed to show it’s no longer selected. Turning off background encoding can help performance if your system seems sluggish.
And whilst checking these settings in iDVD Preferences, make sure that the settings for NTSC/PAL and DV/DV Widescreen are also what you want.

Reduce file sizes with mogrify

I'm creating files with mogrify:
mogrify -quality 25% -type optimize -format jpg ...image.psd
But the file sizes will not go below 33kb, irrespective of how low I make the quality. Using Photoshop I can produce the equivalent image at under 2kb.
Any advise on how to reduce the file size?

To answer my own post; '-strip' solved the problem:
mogrify -strip -quality 25% -type optimize -format jpg ...image.psd

Using Pages with iOS. How do I reduce image file size when I create a document with embedded images?

Hi,
I have created an annual family news letter in Pages on my iPad which incorporates pictures of events, holidays, occasions etc etc. I've then gone to covert it to pdf with the intention of sharing it via email but get a warning message about the resulting file size (in this case 16Mb).
Is there any way of reducing the file size - which is obviously being driven by the images? The pics are being pulled in from the iPad photo library.
Thanks Mike

(1) you are asking about Pages for iOS in a forum dedicated to Pages for OSX.
Most of us aren't using Pages for iOS so it would be more efficient to ask in the forum dedicated to iWork for iOS (at this time this discussion area isn't divided in three areas).
https://discussions.apple.com/community/app_store/iwork_for_ios
(2) As you understood why your file is huge, the answer is simple : reduce the size of your picture files before inserting them in Pages documents.
Drop the unneeded areas, reduce the resolution in tools dedicated to image processing before inserting them.

Retouch photo without reducing the file size/quality?

I have been retouching some pictures for use in a photo book but notice that each time I do so, the file size decreases fairly significantly e.g from 4MP to 2MP.
Is there a way I do minor retouching to a photo without reducing the file size/quality?
Thanks in advance

Where are you seeing this size reduction? What format are the original photos?
For example when you edit a RAW photos you create a JPEG modified version which is much smaller - one I just did went from 17 MB as RAW to 4.4 as a JPEG -- you could save as a TIFF but to me that is not worth the space loss - I seriously doubt that you will ever do anything that you can see the difference in quality between a TIFF and JPEG of yoru images

A simple and free way of reducing PDF file size using Preview

Note: this is a copy and update of a 5 year old discussion in the Mac OS X 10.5 Leopard discussions which you can find here: https://discussions.apple.com/message/6109398#6109398
This is a simple and free solution I found to reduce the file size of PDFs in OS X, without the high cost and awful UI of Acrobat Pro, and with acceptable quality. I still use it every day, although I have Acrobat Pro as part of Adove Creative Cloud subscription.
Since quite a few people have found it useful and keep asking questions about the download location and destination of the filters, which have changed since 2007, I decided to write this update, and put it in this more current forum.
Here is how to install it:
Download the filters here: https://dl.dropboxusercontent.com/u/41548940/PDF%20compression%20filters%20%28Un zip%20and%20put%20in%20your%20Library%20folder%29.zip
Unzip the downloaded file and copy the filters in the appropriate location (see below).
Here is the appropriate location for the filters:
This assumes that your startup disk's name is "Macintosh HD". If it is different, just replace "Macintosh HD" with the name of your startup disk.
If you are running Lion or Mountain Lion (OS X 10.7.x or 10.8.x) then you should put the downloaded filters in "Macintosh HD/Library/PDF Services". This folder should already exist and contain files. Once you put the downloaded filters there, you should have for example one file with the following path:
"Macintosh HD/Library/PDF Services/Reduce to 150 dpi average quality - STANDARD COMPRESSION.qfilter"
If you are running an earlier vesion of OS X (10.6.x or earlier), then you should put the downloaded filters in "Macintosh HD/Library/Filters" and you should have for example one file with the following path:
"Macintosh HD/Library/Filters/Reduce to 150 dpi average quality - STANDARD COMPRESSION.qfilter"
Here is how to use it:
Open a PDF file using Apple's Preview app,
Choose Export (or Save As if you have on older version of Mac OS X) in the File menu,
Choose PDF as a format
In the "Quartz Filter" drop-down menu, choose a filter "Reduce to xxx dpi yyy quality"; "Reduce to 150 dpi average quality - STANDARD COMPRESSION" is a good trade-off between quality and file size
Here is how it works:
These are Quartz filters made with Apple Colorsinc Utility.
They do two things:
downsample images contained in a PDF to a target density such as 150 dpi,
enable JPEG compression for those images with a low or medium setting.
Which files does it work with?
It works with most PDF files. However:
It will generally work very well on unoptimized files such as scans made with the OS X scanning utility or PDFs produced via OS X printing dialog.
It will not further compress well-optimized (comrpessed) files and might create bigger files than the originals,
For some files it will create larger files than the originals. This can happen in particular when a PDF file contains other optomizations than image compression. There also seems to be a bug (reported to Apple) where in certain circumstances images in the target PDF are not JPEG compressed.
What to do if it does not work for a file (target PDF is too big or even larger than the original PDF)?
First,a good news: since you used a Save As or Export command, the original PDF is untouched.
You can try another filter for a smaller size at the expense of quality.
The year being 2013, it is now quite easy to send large files through the internet using Dropbox, yousendit.com, wetransfer.com etc. and you can use these services to send your original PDF file.
There are other ways of reducing the size of a PDF file, such as apps in the Mac App store, or online services such as the free and simple http://smallpdf.com
What else?
Feel free to use/distribute/package in any way you like.

Thanks ioscar.
The original link should be back online soon.
I believe this is a Dropbox error about the traffic generated by my Dropbox shared links.
I use Dropbox mainly for my business and I am pretty upset by this situation.
Since the filters themsemves are about 5KB, I doubt they are the cause for this Dropbox misbehavior!
Anyway, I submitted a support ticket to Dropbox, and hope everything will be back to normal very soon.
In the meantime, if you get the same error as ioscar when trying to download them, you can use the link in the blog posting he mentions.
This is out of topic, but for those interested, here is my understanding of what happened with Dropbox.
I did a few tests yesterday with large (up to 4GB) files and Dropbox shared links, trying to find the best way to send a 3 hour recording from French TV - French version of The Voice- to a friend's 5 year old son currently on vacation in Florida, and without access to French live or catch up TV services. One nice thing I found is that you can directly send the Dropbox download URL (the one from the Download button on the shared link page) to an AppleTV using AirFlick and it works well even for files with a large bitrate (except of course for the Dropbox maximum bandwidth per day limit!). Sadly, my Dropbox shared links were disabled before I could send anything to my friend.
I may have used a significant amount of bandwidth but nowhere near the 200GB/day limit of my Dropbox Pro account.
I see 2 possible reasons to Dropbox freaking out:
- My Dropbox Pro account is wronngly identified as a free account by Dropbox. Free Dropbox accounts have a 20GB/day limit, and it is possible that I reached this limit with my testing, I have a fast 200Mb/s internet access.
- Or Dropbox miscalculates used bandwidth, counting the total size of the file for every download begun, and I started a lot of downloads, and skipped to the end of the video a lot of times on my Apple TV.

How can I reduce the file size of a pdf when exporting?

I don't want to just choose between high quality print or smallest file size.
I want to export it from 60MB to 40MB.
Can I do this manually? When I use smallest file size the quality is too low and the content looks bad.
But high quality print exports my PDF at 60MB which is too big.

You cannot simply legislate the size of a PDF file. If you content is primarily text and vector, there is not much at all you can do to reduce PDF file size other than to cut out content. Otherwise, the only other variables are those of downsampling and compressing the raster images from your content.
You must be very careful in choosing the PDF export settings. The “smallest size” settings yield PDF files that realistically really are not fit for printing and may mess up any CMYK colors. The “high quality print” and “PDF/X-4” settings yield best print output, but yield the largest PDF files since they do less image resolution downsampling and only the maximum quality lossy JPEG compression.
I would recommend that you start with either the “high quality print” or the “PDF/X-4” settings and make a custom set of export settings. Assuming that you aren't going for offset or gravure printing, change the color image and grayscale image downsampling values from 300 and 450 to either 200 and 275 or no less than 150 and 225. If that doesn't give enough file size reduction, change the compression image quality from “Maximum” to either “High” or no less than “Medium.” Beyond these changes, you may end up with PDF files that will neither print nor display with any reasonable quality.

How to reduce image file size in spreadsheet

I have created a spreadsheet that contains cells with small amounts of text, and images that I brought in from the Media Browser from iPhoto. This has caused the file size to become HUGE, on the order of 234 MB. Saving it as a pdf only reduces it to 220 MB.
I have tried the Format>Image>Reduce Image File Size, as well as File>Reduce File Size, but in both cases, those options are grayed out.
What am I doing wrong? All I really want is thumbnail versions of my image files.
I don't understand what the Reduce Image File Size command would be used for, if it doesn't work for this?

When you insert a picture in a cell, it's used as a background.
To do that, the app keep it in a size allowing it to accomodate the larger cell size permitted.
If you want to get small images matching the cell size which you use, you must reduce the picture by yourself before inserting it. For instance, cells are often 72 * 16 pixels ones so you may reduce your pictures so that thir width become 72 pixels.
Of course, if the user enlarge the cell, the picture will become highly pixelated.
Look at this example.
In B4 is the original : 202 x 177 pixels
In C3 is the reduced one : 72 x 63
in B2 is the reduced one in a 202 x 177 pixels cell. It's awfully pixelized
We must arbitrate between size and quality.

How can I reduce the file size when saving a psd as a pdf

I have a psd with graphics and text, it is 8.5 x 11, 300 ppi
I flatten the image and go to save as .pdf I un-check all of the options in general.
In compression, I have tried a dozen different combinations and the way I've found to get a document that is not pixelated or blurry is to use jpeg 2000 > lossless or jpeg > maximum.
So I have a high quality document but the file sizes are around 900 kb.
I have downloaded other people's documents of the exact same type and size (8.5 x 11, 300 ppi) that I am making and viewed them in Photoshop, they are not pixelated or blurry and their file sizes are 300 kb or even less than 200 kb
How are they doing this?!

Delete all unused, invisible layers.
Sometimes zip compression is better than jpg compression (in the pdf output settings). Zip is lossless, and works better with non gradient colour or no images.
Flattening the image before you save it to pdf can reduce the file size if you are using jpg compression.
Post a preview of your pdf and we can comment further on how to reduce the file size.

How to reduce jpg file size, not pixel dimensions?

I am preparing images for the web and I really have 2 questions: one about gifs, and one about jpgs.
My standard procedure is to reduce the image to the desired pixel dimensions at 600 dpi
That gives me a crisp small image. then I either use it as is if the file size is low enough (I try for under 600 kb) or convert it to a gif with the save for web and devices tool.
So here are my 2 questions (I will count this solved with either answer)
1) When I convert to a gif I have the 4 boxes: one with original size, the other 3 with options but often the options are too low res for me How do I change my 3 options to start at a higher gif res?
2) If I try to reduce the file size of the jpg in the image size box I set the resolution lower ( 400, 300), which lowers the pixel dimensions and the filesize, but I don't want to cahnge the pixel dimensions. And If I reset the pixel dimensions back to the size I want them, even though it is a lower resolution the file size doesn't change. How to reduce jpg file size using only the resolution, not pixel dimensions? PS I have tried messing with checking and unchecking the 3 little boxes( scale styles, constrain proportions, and resample) but nothing has worked.

Gif is not a great filetype, especially if you want a crisp image. What are your pixel dimensions?
For web, it makes no difference what the dpi is, only the final pixel dimensions so once you have that as you want, use 'Save for Web and Devices' and you can lower the quality - 100% being max and 0% being lowest. I wouldn't save anything below 55%. For a 600kb image, your dimensions must be rather big.

Reducing AI file size, without converting to another file type CS6

I designed artwork for a large banner (84" x 32") so my AI artboard is that large. As you can imagine, with all the text and graphics I used, this file size is 22.8 MB. I need to email this art to the printer, but the file size is too large to email. How do i go about reducing the file size in AI so it still maintains large format print resolution? Will saving to a PDF lose the print quality? I'm at a dead end... help!

For a 84" x 32" banner (vinyl, fabric/paper) a small amount of compression should be fine.
I would start out with the high quality setting which gives you compression but at maximum quality 300 dpi. this should make your 22.8mb file much smaller, (my guess without seeing your art is you have an image in there and will get under 10mb)
If you need a smaller file yet, go down to 200 dpi (change top 4 values to 200) and max to high quality to make the .pdf even smaller, and for a medium sized banner as you have that would look very good and you would have to look hard to see the difference, at a distance would be unnoticeable.

How can I reduce the file size rendered by After Effects?

When I render a relatively simple 5 second project in After Effects, the file size of the resultant .avi is 64MB. If I change the properties to reduce the file size, the degradation makes the file unusable. What am I doing wrong?

Is AE's encoder really that inefficient?
The thing is, AVI doesn't mean much.
It's pretty much an empty container box, which doesn't imply a quality level.
So, AME could default to something completely different as a starting point to produce an AVI file.
AE defaults to uncompressed video when you pick AVI as a format. So, obviously this produces huge file sizes. There could be similar quality thresholds with smaller sizes if you pick other AVIcodecs, but that's a different subject. And in any case, when you're rendering a production quality master, file size is usually not your main concern. You typically use this high quality video file as a source for compressed flavors for distribution. So, pristine video files with huge sizes are a good thing - people then wonder why trailers at apple.com, for instance look so good. And the thing is, the most compressed formats benefit enormously from having an uncompressed file as a source.
Regarding encoding efficiency, yes, AE is less efficient than dedicated encoding solutions. Above all, because it doesn't support 2 pass encoding. Note that for some formats, 2 pass makes a night and day difference, while for others, nothing as drastic as most users seem to believe.
All of this is a moot point for AVI, because the default AVI codecs don't offer these encoding options, which are more the realm of distribution formats like FLV, MPEG-4/H264 or WMV.
There are distribution codecs which use AVI as a container out there, but those are a different case.

Reducing audio file sizes

I'm using imported audio files in my captivate. They were
encoded at 128 and are mp3. When I import them I think captivate
converts to WAV? I don't know why that would happen. But when I
change the audio encoding settings from the default of 64kbps to
32kbps and then publish, the first thing that happens is that it
shows that it is converting each WAV to MP3 (even though I imported
the files as mp3). Also, it sounds awful encoded at 32. I tried it
at 48 and it still doesn't sound that great.
Is there a better way to reduce file size with audio files? I
thought about going to the source files and re-encoding in audacity
and then importing. Would that help? If I did that, what would I
set the encoding rate to?
Thanks,

Your observations are dead-on. The Adobe Captivate
methodology is to have a high resolution sound container (WAV) and
then let the user compile to other sound quality levels. You are
correct that your MP3 is being converted to WAV.
There have been several posts here about sound quality in CP4
and I am in complete agreement with them about the poor quality of
sound. It appears that the sound driver is choppy in CP4.
Some of the users and active Forum members have done sound
experiments with regard to size. It appears that higher encoding
rates have a minor effect on file size. Go ahead and crank up the
sound quality and monitor your file size. With a small increment in
file size, you can improve the sound quality. My experiments for
getting "good" sound quality have produced only "fair" results and
I find the sound quality to less than what I want in almost all
conditions.
Please voice your complain to the Adobe Tech Support people.
They need to hear this over and over again to get this flaw
repaired.
My second pet-peeve about sound is a lack of a user defined
sound level (gain) in the form of a slider pre-amp. The automatic
setting seems to over-boost the sound levels and that introduces
white noise at low sound levels (soft passages or longer pauses).
If you find the same thing, please add that to your complaint when
you contact technical support.
The sound issue needs to be put to Adobe for proper repair
and I'm not alone in trying to "turn up the volume" on this issue.

How can I reduce the file size of 3 videos?...

...without losing quality? These three videos are as follows in terms of size and length of the video:
1) 148MB 19minutes
2) 357MB 18minutes
3) 164MB 14minutes
I tried using a video converter to reduce the bit rate in order to reduce the size, which i know affects the quality, but that did not actually work to reduce the file size this time.
I thought perhaps i should ask my forum friends for help on this matter. How,if at all, can I get all three of these MOV's under 100mb or to a total of 300mb for all 3 and preserve quality? It has to be able to play on an ipad (MOV or MP4). Thanks for your help!

I think that the point that David was trying to make is that reducing the amount of information originally provided by a product or part of it in order to make it smaller will inevitably reduce the efficiency of the product itself.
However, you don't have access to the original masters? Then you might be after a good compromise, meaning a video that can display decent quality while playing at its original frame size (say on the web).
Does this mean that there is no real way to reduce the size without losing quality?
If your target is the web there is a way to reduce the file size and still make it look decent enough. Re-compression means loss of source information but video compression is an art on its own and can produce some amazing results!
Not without testing though.
Now back to my previous post, use Compressor to try to reduce the file size and compare the result quality. Trust your eyes and be honest with yourself.
