In Snow Leopard, I could create a custom ColorSync profile to reduce PDF size (but not with quite as a dramatic drop in quality as the default PDF Reduce File Size) and it would show up in Preview as an option.
Now, in Lion, I still have the profiles, but they do not show up in Preview as a choice. I also cannot edit the default Reduce File Size profile in ColorSync as it is perma-locked.
MacBook Pro, Mac OS X (10.7)
The solution I realized involves the following:
I hope this workaround can hold up for now. I do admit I miss the ability to see and use my quartz filters right out of preview.
Take care.
I have OS X version 10.11.3 and I was able to use the pdf quartz filters, but NOT from the original file. I first had to create a DUPLICATE from the Preview app and when I was prompted to save it, the pull down menus for the filter options were made available to me. I was able to reduce the size of a color scan (9.3MB) to a B&W file (1.8MB).
While this may be an old answer, it was new to me!
I hope this helps.
I also have 10.11.3 and here's what I did to make this work...
Step 1
go to HD/Applications/Utilities/ColorSync Utility
click the + at the bottom to create a new filter - named it 'Compress PDF'
left click on the circle down arrow on the right side of the window - Add Color Management Component > Convert to Profile
In the drop down select Generic RGB Profile > All Data > All Objects
left click on the circle down arrow on the right side of the window again - Add Image Effects Component > Image Compression
In the drop down select JPEG and move the slider to about 1/4 of the way from the min
Step 2
create a new folder named Filters and place in HD/Library
Step 3
go to HD/Users/Name/Library
if the Library is not visible then it has been hidden -
if visible, select the Compress PDF filter and move it HD/Library/Filters
The Compress PDF filter should now be visible at top of the options when saving a file in Preview
Now, can someone show me how to restore Compress PDF in the Print Dialog Box under the PDF options?
so helpful, thank you. El Capitan.
