    Thanks a lot. It's very useful to turn large pictured documents into net sendable files.

    tks a lot for the filters, quite a good idea.

    Actually I tried to tweak withe the filters too and I got always the same problem which is: I have a file I created with Word for Mac, mainly it is a table with some pics and descriptions.
    The file is 4 Mb, if I save as PDF it becomes 4.8 Mb, If I save with the option "reduce file size" it keeps 4.8 Mb, if I save with a filter, ANY filter, it becomes smaller (2.1 Mb, which is still a lot) but the first three pics become black.
    I created the file in the same way, the pics are all the same size, I really cannot understand anymore, after some serious efforts and time spent to try to save in different ways why the first three pics become black and the others do not do.....
    If anybody has some idea it would be greatly welcome.... tks

    Is this a crazy question? I wonder, since no one else has posted it. Maybe I'm letting my novice-ness show thru.

    How do I know when I save as "Reduce to....(anything)" that my 2.8MB file is not already smaller than what I'm choosing, so I actually INCREASE my file size?

    Is there a way in Color Sync Utility that I have not found to preview the file size before applying filters?

    All this used to be available built in with Tiger. There is a reader down there somewhere that is still on Tiger. You go through the process 'Save As' > Quartz Filters to reduce file size ..... then in Tiger it was possible to scale the file size reduction to get optimum results ... I don't remember exactly how now but it was a wonderful gadget. Why on earth it disappeared in Leopard is beyond me.

    Am I the only one? I have 10.5.7 with Mac G5, Adobe Acrobat Pro 7. I downloaded the Filters folder and placed it in the Library. I opened 35mb pdf file with hi quality photos, in preview, and clicked "save as" and selected the compression in the quartz filter dropdown menu. When it saved the file the images all came out black, blue, grey, etc, not the original tones. Not helpful. Can you please assist? I also tried the Colorsync Utility and the app did not allow me to edit the parameters. Thanks.

    Michael, see the earlier comments about inverted colors. Apparently the JPEG compression filter doesn't deal well with CMYK images - you'll need to add this filter to your chosen profile using ColorSync Utility:

    *Convert to Profile*

    Lynsun, your thinking is correct, the filtered result may well increase the file size. But a file size preview is probably not necessary, just save the file to a new name so you don't overwrite the original, then see how big it comes out.

    This was SO helpful! I had a file that needed to be slightly smaller to fit the website upload requirements, and the "Reduce File Size" quartz filter in Preview/Color Sync Utility made it too poor of quality for me to use. Thank you SO much for your help!

    Hi can you please explain in more detail exactly what needs to be done here to fix the problem with compressed file sized ending up actually larger. I can't find any option in the Quartz Filters to add this profile.

    I did not read through all the post so if this is a repeat, I apologize, but I found this trick today. You can reduce .pdf file sized by creating a custom quartz filter in ColorSync Utility. Check this out:
    By doing this and adjusting the quality, I was able to get a 12M file down to 608K with great quality.

    I'm a complete novice at this.

    I've downloaded Jerome's files. How do I get them to work? I've opened ColorSync Utilities for the first time. Do I put Jerome's files into ColorSync? I tried drag-n-drop, File > Open but no luck. If they don't go in ColorSync how do I get them to show up in Apple's "Preview" Application?

    I'm also having the color inversion issue from InDesign exported pdf's. So I'm piecing together instructions from here:

    And Here:

    Has anyone done the whole thing?
