Reduce jpg. file size

a website requires jpg. file size to be reduced to 5000kb. i'm at 1.1mb. how do i reduce it to the required size?
rsvp...

5000kb is 5 times larger than 1.1 MB
Anyway: File -> Export. In the resulting dialogue "Size" refers to the dimensions of the photo (length by breadth) and Jpeg Quality refers to the file size. Lower Quality means smaller 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.

** Reduce jpg file size...returns black image

Hey Guys,
I have this function to reduce the image file size.
It works but returns a black image when I view it.
This code is what I have found on other boards...I just can't seem to get it to work..
Any ideals??

Hi Andrew,
Thanks for your reply..Your links sent me to this ...
Page Not Found
We are sorry, the page you have requested was not found on our system. >Ahh. That is because I foolishly hand edited those links and did not check them. They included 'api' twice.
In any case they were simply the links to the javadocs for those two classes.
Search [google for bytearrayoutputstream|http://www.google.com.au/search?hl=en&q=bytearrayoutputstream&meta=] and you will end up in the same or similar place.
As to using them, you simply put an appropriate ByteArray stream in place of the other streams (e.g. File based) that you were using.
I'd have to search for an actual example, but you could do the same (probably faster).
Edit 1:
Adding 'imageio' to 'bytearrayoutputstream' as a search led to this as top hit [Memory Efficiency of BufferedImage and ImageIO|http://forum.java.sun.com/thread.jspa?threadID=5261937&tstart=0].

Email-to facilitate emailing a photo by gmail or AOL, I reduce the file size. Is it better to reduce the image size or increase the jpg compression?

To facilitate emailing a photo by gmail or AOL and avoid overwhelming the recipient's screen, I reduce the file size. Is it better to reduce the image size or increase the jpg compression? I have been making a duplicate image of 35 MB and reducing the image size to 8"x12" at 72 resolution giving a file size of 1.4 MB. Then I SAVE AS a jpg of medium compression giving a file size of about 111 KB. Overkill?

Go to File>save for web.
I usually make the long side 800 px
At the bottom of the dialog, check "constrain proportions."
At the top, select JPEG in the dropdown for the file format.
All the work is done for you! 72px/in is ok for web work. 240-300px/in is the recommended range for printing.

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.

Why is Photoshop Touch reducing my file size?

The original photo I'm working with is 2.6 MB taken with my iPhone, editing is being done in Photoshop Touch on an iPad 2. After adjusting contrast and color and trying to export, the file is 41kb. There don't seem to be any tutorials on exporting projects, and the only options are exporting as JPG or PNG, and both are reducing my file size. Is there a way to adjust file exporting preferences? I want the full resolution of the file to be exported when I am finished.

PS Touch only permits JPEG and PNG when exporting directly to your device. Exporting by "sharing" (rather than "save to") via a service like Dropbox permits the full range of file formats (JPEG, PNG, PSD & PSDX).
Not sure what's causing the file to shrink so considerably. My projects, provided I kept the same dimensions, are generally the same size as my originals when I save locally. (I'm on Android.)

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 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.

How can I reduce the file size when PDF Optimizer does not do much?

I have a PDF form that exists of 48 pages. 44 pages are forms / have form fields, the other 4 are just informative. Each form-page has approx. 80 fields (checkboxes, text fields).
When I started setting up the PDF form the file size was 12 MB and I had placed fields on 21 pages. Then with 34 pages the file size was 19 MB. And with 40 pages it was 35 MB big! Finally with 44 pages the file size is 34 MB.
So I searched with Google and found some tips. Using the "PDF Optimizer" option inside Acrobat for example. So I did, and the file was reduced only with 3 MB... 31 MB was the file. Also used the option "Save as.... Optimized".... no difference. I also found a suggestion about removing embedded fonts. Using the "Audit Space Usage" option I noticed the fonts taking many MegaBytes:
* Content Streams: 5.287.000     15,09 %
* Fonts:                24.556.810     70,08 % !!
* Acrobat forms:      3.349.164    12,05 %
In the older PDF version (I saved and kept this one too) with just 21 pages with form-fields, the "Audit Space Usage" shows:
* Content Streams: 5.292.000     40,14 %
* Fonts:                 1.290.224     9,79 %
* Acrobat forms:      1.588.758    12,05 %
So I could save many many MegaBytes by -UnEmbedding- fonts. But if I do this (unembed ALL fonts), the file size stays almost the same!?!?!? Why? What can I do to reduce the file size? I would like it to be 8 MB if possible (32 MB - 24 MB = 8 MB)?
Thank you for your help!

If you have authored the form, reduce the number of different fonts for the content and form fields.
Any font used in a form field will cause that font to be embedded into the PDF.
If you are going to Optimize the PDF be very careful with forms. Optimization does a lot of removal of items and rearranging of items which can really mess up forms.

How do I reduce the file size of a pdf to email?

I have a 260 MB pdf file generated from Photoshop 6. I can't seem to reduce the size in Photoshop. Is there anyway to reduce the pdf outside of Photoshop? Thanks in advance for any help.

Hi Scott,
That's a pretty big PDF! You'll have to reduce it pretty dramatically to attach it to an email. But, you can use Acrobat to reduce the file size. Please see this video for pointers: https://acrobatusers.com/tutorials/how-to-compress-a-pdf-file
If you don't have Acrobat, you can try it for free for 30 days. For more information, see www.adobe.com/products/acrobat.html.
Best,
Sara

How do i reduce the file size of a picture?

I am trying to reduce the file size of a picture? It is 1.7MB and I need it to be smaller.
Help?

File -> Export
The two settings that most affect the filesize are Jpeg Quality and Size.
This User Tip

Exporting a book to pdf - any way to reduce the file size?

Hi,
So I have made a book using iPhoto and would like to send a pdf copy of it to another person who will fill in the texts. I am able to save the book as pdf via the print menu but the resulting file is over 300 mb in size (the book has only 20 pages)! On the one hand i like the fact that iPhoto is not downsampling my photos but it's a bit difficult trying to send a 300+ mb file over email Is there any way to create a pdf with the images compressed so i could send it as an attachment?

Reducing Pages file size on iPad

I produce a 12 page newsletter comprising text/photo mix for a charity. Unfortunately the file size saved as PDF was almost 20mb which seemed enormous for the content involved. I put the photos through a file size reducer and reimported them but this saved only 4mb. I can't email the document to the majority of subscribers as its so big. How can I urgently and drastically reduce the file size on an iPad so I can send it.?

An other explanation may be the way Pages store characters.
Most of the characters available in the old ASCII set are stored as is using a single byte.
Some of them "&" for instance are stored as a descriptive string requiring several bytes.
& is stored as &
Every other characters require six to eight bytes.
é is stored as é
œ is stored as œ
ᴂ is stored as ᴂ

Reducing MP4 File Size for online upload

I have a short HD video almost 1 GB in size (impossible to upload online). Is there an easy way to reduce the file size using IMovie or another program that I don't have to go out and buy?

I don't think you'll have too much success with this. Mpegs are already compressed files, so there's no real benefit to trying for further reduction. In some cases using compression software will make the resulting file larger than the original.
There are utilities that can be used to slice up a file into smaller parts that can then be reassembled. For example, Movie Cutter, SplitFuse, Split&Concat, MacAppStuff Pieces are a few. Look for them at VersionTracker or MacUpdate. Stuffit Deluxe is a commercial product that includes the ability to split and join multiple pieces of a file archive and has the benefit of being available on both Macs and PCs.
You can then split a large file into several smaller files to send via email or to upload to file server sites. Of course the recipient will need a compatible utility to join the pieces.
