    It works perfect. However, I am using Maverick and probably that is the reason I see the Quartz Filter cut.

    Hopefully you could help me to fix this.


    Thank again.

    Hi all. This method is a great idea. Thanks to Jerome for this great contribution!


    Is anyone else having trouble with Mavericks? I first followed the old instructions, and copied the filters to ~/Library/Filters. Then when I started preview, I got the spinning beach ball. After about 10 seconds, it stopped. The preview window was present, but the menu bar did not show preview. Expose did not show preview. I quit the window. I can see it via "ps -axf | grep -i preview" and kill it accordingly.


    So I thought maybe it did not work with my Mavericks. No problem. I removed the Filters folder. (It was not previously present, I had created it). Then logged out, logged back in. Still today when I start preview, I get the spinning beach ball followed by now menu, and unusable preview.


    If anyone else has this trouble, and found a fix, please share.

    I have found that the above problem is limited to the command line opener. In other words, if I open apps via dashboard or launch pad, then all is well. But if I open via cmd line "$ open blah.png" then the above problems occur. This problem persists for any type of file opened, such as jpg, pdf, docx, etc.


    So how is it, that simply copying some new quartz filters into ~/Library/Filters broke my command line opener? Any hints appreciated.

    I am using 10.9.4 and there is no PDF Services folder in the Library.  Is there a new location now to install the filters?  I installed these filters on another laptop before i upgraded to 10.9.4 and can't even find them in the other directory now, so evidently they've been hidden, so where are they now located?

    I have been looking for this solution for years. Previews reduce file size is useless.


    THANK YOU JEROME, I would buy you a snickers, or your candy of choice if we worked together. You have saved me so much time and pain.

    Hi wfstephens.


    In 10.9.x (and probably 10.10) there is a "PDF Services" folder on your hard drive.

    It is in the "Macintosh HD/Library" folder, or whatever the name of your hard drive is /Library.


    If you are looking in the Library directory within your home folder (the one with a house icon), it is normal that there is no PDF Services folder.

    I love how simple and intuitive apple makes their software!  nothing at all like confusing microsoft software with hidden features in a place that makes no sense. 


    or is this the microsoft site? so confused.

    This is a nice utility, but I have to say that, half the time I use it, it makes my pdf file bigger. Sometimes a LOT bigger. A lot of us see that. So when it makes it smaller, great, smiles, and kudos. But when it doesn't, I guess I'll just shrug. It really surprises me that, to my knowledge, there is no explanation of what kind of pdf file this utility works well on, and what kind of pdf file it doesn't.

    Thank you soooo much for taking the time and effort to share this with everyone, Jérôme!! I remember your post from over a year ago and how kind you were to help me when I had issues installing it back then. I just had my computer restored to factory settings and right away one of the very helpful things I required was the ability to easily reduce PDF file sizes. I am so happy and thankful to see your very helpful post here. Your instructions are very clear, easy to follow and it worked right away for me   I see previous commenters have offered you candy to thank you LOL If you're ever visiting Toronto I would love to grab coffee with you to thank you.

    This worked for me:


    1. emailed myself the pdf file

    2. opened received email > file > export as pdf to desktop

    3. opened pdf on desktop > view > thumbnail > dragged particular page of document to desktop

    4. re-saved


    file size was automatically reduced from 9MB to 581KB.

    Works like you say it does. 

    Also just to confirm that this works on Mavericks 10.9.5!


    Thanks Jérôme !

    Hello Jerome Colas,


    thank you very much! Your advice works even on Mac Os 10.10.2 perfectly. Such a helpful advice.

    Just upgraded (time will tell I guess!) to Yosemite.  Re-installed quartz filters and they work like magic.  Thanks Jerome for the gift that keeps on giving.

    Hello Jerome,

    Thank you for reposting this, again.

    I have saved all of your info, so I can try this on PDFs I create using OS X Preview in the future.

    Great info and procedures on how to reduce PDF file sizes without having to purchase very costly Adobe Acrobat Pro.

    I bought Acrobat Pro for a much earlier Acrobat version. i used it, but did not like it or its interface much.

    So glad you found a way to introduce some of Acrobat's functionality into the OS X Preview app.

    Good Stuff!!!
