    Hi actionmarker and thanks for your in put.

    The functionality is part of OS X indeed, as explained in my otiginal post, and those filters are just simple filters made with Colorsync utility.


    2 filters are applied : image downsampling (reduction of dots-per-inch) and (jpeg) compression.

    The workflow you describe works well ; however it only uses compression, which might not be sufficient for high DPI documents.


    Here is an alternative workflow (the filters described here need to be installed) to crete compresses versions of PDF documents selected in the Finder :

    For those who would like it, here is the finished droplet : drag PDFs onto it and it will make copies of them with the "standard" 150 dpi average quality filter. ip


    Hope this helps,

    This is driving me absolutely nuts. I've used these before on Snow Leapord and they worked a charm. After upgrading to Mountain Lion - I just can't seen to get these to work.


    I've put the filters in the correct place, and indeed, when I export - I can see the options there.


    The issue is: the file size isn't reduced. It's exactly the same. I'm pulling my hair out here to try and find out what's going on - but just can't find the issue.


    If anyone else has had the same experience and managed to resolve it, I'd be grateful if they could enlighten me!

    Hi Rapidz.


    One reason why the files' size would not be reduced is if the files are already 150dpi or less and already have some compression (such as jpeg). In some cases, they could even get bigger.


    Could you please post a (not confidential) document that the filters fail to shrink, so that we can see how it works on another Mac?


    Have a great day,

    I've looked everywhere for a way to reduce file sizes on my Mac, and this worked perfectly!  Thanks so much!!!

  • barnettgs Level 1 Level 1

    Brilliant work Jerome!


    This has reduced the file size from 370 MB to 28 MB while keeping the quality great! 


    Works on Mavericks.

    Thank you, Jerome! You're an absolute lifesaver! I have been trying to reduce a very large PDF file (magazine) for hours and was about to give up when I came across this thread. Your filters worked flawlessly! I did have the color inversion problem, but as soon as I added the color profile to your filter using the Color Sync Utility, the file saved and displayed perfectly!


    I was able to get a 550 MB file down to 8 MB! It's still a scrollable PDF and looks fantastic. This is going to work perfectly for web viewing and email.


    Thank you times a million!

    Confirming that it works on Mavericks and the location for the filters is the same as it was in Mountain Lion. And chiming in with a "Thank you, Jerome!"

    For the sake of feedback - here's another convinced user of your filters!

    Works well on Mavericks 10.9.1.

    Keep it up!

    Have you tried just downloading it again?

  • Raylenefromca Level 1 Level 1

    Once you've reduced your PDF to a management size, I found a great program ($1.99) in the app store that lets you split PDF files, add and remove pages, etc.  Very useful for the price.  It's called PDF

    Toolkit +.

    In Mountain Lion you don't need to download the filters. Just go to Export and select Reduce file size in the Quartz filters box
