Reducing Keynote File Size

Does reducing the size of a Keynote file degrade the visual quality of the presentation?

Perhaps the file is just large, and you've done everything possible?
One other thing you might want to try is to do a "Save As" with another version number. I just did that to a file that was 27.2 MB and it shrank to 25.4 MB. Not much, I know.
I don't know how KN works internally, but a program like Adobe's InDesign stores all the changes you make to a file at the end of that file (if I understand correctly), and when you do a Save As, it rebuilds the file and gets rid of all the old info.
Just curious, how big is your file, what's in it (lots of images?) and how small were you hoping to get it?

Is there a way to "compress" or reduce keynote file size?

I have transferred some PowerPoint presentations to Keynote and in general have had no difficulty. However, I can "compress" the pictures in PowerPoint which makes the file size much smaller.
Is there any way to reduce the file size of a Keynote presentation?

hi I am trying to do a project of putting a keynote saved as a quicktime into garageband and adding audio and then compressing it via Share ...sent to itunes etc. It does get smaller.
But Are there any experts out there on putting a keynote with narration into garageband. I loose all of the timing control when I send it to quicktime. It seems like a LOT of steps.
Also, putting a narration into keynote is so long. Power Point just lets you record the narration on each slide. So I was putting it into garageband and trying to add the narration podcast style. Any suggestions.

Keynote file size vs. PowerPoint

I just created a KN presentation that was 5.9GB. When I convert it to PowerPoint, the same presentation is only 500 MB. What could account for that difference? How can I make the KN presentation a more manageable size?

I should have been clearer. No video at all, but a number of photos, nearly 300 of them, plus a few bullet-point slides. Some of the "photos" are images downloaded from the web and imported into iPhoto, but most are ones I took. I did not do anything to alter the resolution of the photos when importing them from iPhoto into Keynote, nor when converting from Keynote to PowerPoint. The photos appear on the computer screen to be equally clear in Keynote or PowerPoint. I don't understand how PowerPoint can do the same job so much more efficiently, or why converting to PowerPoint reduces the file size so much. I like Keynote, but I would like to know how to make the file smaller to be able to share it on a thumb drive, etc. Otherwise I'll just go back to using PowerPoint.

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.

Reducing PDF File Sizes

We create and use numerous pdf files, some with fill-in fields and some without. Is there a way to reduce the file size without adversely affecting response time to open the file? Some of us are running Acrobat Professional version 7 and others are running version 8. Some of us have Windows XP and some have Windows 2000.
Any help you can give us would be greatly appreciated.
Thanks.

>I thought that if a file was compressed in some way that it might take some time to decompress the file.
I see - entirely reasonable to think that. However, almost every PDF
is already compressed using technologies like ZIP or JPEG. When you
reduce the file size you are usually doing some combination of
* reducing image resolution
* using more agressive JPEG compression
* deleting stuff you can live without
So this doesn't affect the load time.
JPEG 2000 compression is stronger and a bit slower, but probably
nothing to worry about, especially if you don't have high resolution.

How do I reduce the file size of my pictures

I am running out of space on my hard drive and notice that my iphoto library contains over 5000 pictures and is about 15GB. This is about 3MB per picture. I checked and lots are over 10MB. Most pictures I only print in 10x15, the largest i ever printed was A4 sized. I guess i don't need to keep such large files. These cameras are now set to make pictures with too many pixels I guess...
does anyone know of a way to reduce the size of all my picture files?
thanks

1. Reducing the file sizes of your pictures will not just reduce their quality when you print, it wll also negatively affect their quality no matter how you view them. Remember the screen quality on your next mac will be better than this one, and even more so on the one after.
2. The simplest solution to a size issue is to store the Library on an external disk, You can do this with iTunes and iMovie too.
3. If you really want to reduce the quality of your photos then there is no way to do that in iPhoto. Here's what you'd have to do:
Export the Pics from iPhoto (File -> Export) and in the Export dialogue make your choices on Jpeg Quality (the amount of compression used) and size (the dimensions)
Delete the pics from iPhoto
Import the ones who have exported back to iPhoto.
Give away your camera and get a lower quality one
