I'm having a devil of a time with prints to pdf ending up at 40 or 50 Mb and scans doing the same.


I was advised to dowload ColorSync but can anyone help me figure out how to use this to downsample pdf's? I'm reading the help and can't figure it out.


Also, when printing from PREVIEW to pdf are there settings or pulldowns which I can use to set the DPI or otherwise keep the file size down??

    Hi. Thank you very much.


    Is this for pdf once it has been printed out of Preview?


    If so, am I correct in thinking this means I print to pdf in Preview, Open the Document in ColorSync, then select Save > Reduce File Size (pulldown in "Quartz Filter"), is that right?


    I gather this will over-write the old file and also does anyone know if there is a way to print to pdf out of something like Preview or Pages in a way that does not result in 50 MB files?

    The quartz filter is in Preview, Colorsyc has nothing to do with it.

    Hi. Thanks. I am on OSX 10.6.


    I have two issues.


    1. PDF's are huge and I need to downsize them periodically.

    2. I need to prevent them from becoming huge when I print (but I also need to /downsize/ them when I have them on my hard drive and they are too big to email or keep that way on the HD).


    I am a new user so can you help me a little here?


    What are the steps to getting to the image you show? Say I have five images or scans open in Preview. You are showing me how to print to pdf but in a way that will keep the file size small, yes?


    If so, I go to Print or Print Selected and then what? Do I have the "Preview" pulldown set in this dialog, do I have the Format pulldown, do I go to the pdf pulldown in the lower left hand corner?


    I have not been successful with this but I'd like very much to be.

    I have no idea where you are getting the idea that I suggested to print, I clearly posted a picture of the 'save' dialog.


    Open a pdf in Preview, select Save, choose the filter option you want (in this case reduce file size) and save it, I really don't understand what is the difficulty here.

    It's email.


    That means you and I have to make sure that we are both taking each other seriously and using the MFI (Most Favorable Interpretation).


    This is helpful. Apparently there is other functionality for downsampling in ColorSync.


    ALSO, I need to figure out how to PRINT pdf's so I don't have then reopend them and save them out as smaller sizes in Preview (as you describe) or with ColorSync (as others suggested).


    No difficulty except that I have a couple of issues I am trying to make sure I am doing correctly on a new OS with new software.


    Thank you and goodwill.

    What are these PDF files being created from? You mentioned scans. Are you just turning the scanned images into PDF?


    If so, all you're doing is embedding a raster image into a PDF wrapper. It's not going to get smaller just because it's in a PDF.


    If you do reduce the size, as Csound1 has shown (it's one way to do it), the file will get a lot smaller, but at the expense of both reducing the number of pixels in the image, and turning the embedded image into a highly compressed JPEG. Doing that will turn your image into junk. So if maintaining image quality is necessary, you do not want to reduce the size.

    Take a look at the first post in this long thread:


    The link to download his compression filters now renders with an extra trailing asterisk, giving an error. Without the asterisk  it redirects to:


    The added filters give a number of choices:

    Hi. Thanks. OK but 10 or 20 page prints out of pdf are coming out at 50 and 60 MB. Ideally I'd like to be able to control this - if say i want to email it - without constantly printing to pdf and then re-opening and saving over the document i just printed.


    I understand that part of this has to do with the initial documents - png's or whatever - but it is less than ideal to go back and scan at a lower res just so i can email a document.


    anyway, i am new to the os and to the software so I am always really grateful to any ideas assistance etc.

    Thanks. Csound1.


    This helps me get it going over here.

    Cheers and thanks.

    Thanks man.


    It's not a bad idea to try and bump up the degree of difficulty by trying something like this.


    Plus I need it to work easier.

    Cheers and thanks.

    Hi jsd,


    Is there a functionality that you know of that will do this for PRINT? It seems to me that you have to get it to a (large) pdf first and then SaveAs using these options?


    I mean this is fantastic (THANKS) but there is another side to this which is opening images and then printing to pdf, yes?


    Also, I gather that buying Acrobat doesn't fix this because there is some issue about what it can't do in Snow Leaopard?

    Here's a further project for you!

    How to automate application of quartz filter to scanner output?

    (see the 10/8/11 post)

  • jsd2 Level 5 Level 5 (6,200 points)

    Our last two posts crossed.


    The idea behind the Automator folder action described in the other thread is to create a special folder, perhaps on your desktop, such that any PDF file that is placed into that folder  gets automatically compressed  by whatever Quartz filter you chose when you created the Automator workflow (I'd choose the "standard" 150dpi, average quality filter.)  That avoids having to first open the large PDF in Preview and then re-save it.


    I don't know anything about changing size as things are printed, or about Acrobat.
