"In Illustrator, we make our PDF files via File > Save As: Adobe PDF. But Illustrator makes the PDF file sizes VERY large, even when saving as Smallest File Size. What can we do about this?"
All recent versions of Illustrator default to saving a copy of the entire .AI file inside the saved PDF file, so that Illustrator can open and edit the PDF file later. This makes it handy if you don't want to keep track of a separate .AI file and .PDF file. You can have a single PDF file that is editable in Illustrator, but also viewable by others with Adobe Reader. The big downside is that the file is large.
The workaround is to just save and maintain a .AI version of the file for editing purposes, and a separate .PDF file for sending you your print vendor or for others to view. Here's how:
First, make sure you've saved your work as an Illustrator .AI file.
Next, choose File > Save a Copy, choose Adobe PDF for the Format, and click the Save button, you'll see the dialog pictured below.
Just deselect the Preserve Illustrator Editing Capabilities option, then click the Save PDF button. You may see the warning pictured below. If so, just click the OK button, as long as you've previously saved a .AI version of the file.
The exported PDF file should be much smaller.
After that you can also use Acrobat to make the file smaller. Choose Document > Reduce file size. Use the default settings or adjust to your needs.
ReplyDeleteAnd to make it eeeeven smaller... zip it before you email it.. but PDF's are probably the most secure file you can send over the internet.. zipping is really not needed. : )
ReplyDeleteI cant believe it, I have struggling with this issue for months. Thank You.
ReplyDeleteBig pat on the back for you mate. Just like 'davis' I have been scratching my head over this for a while.
ReplyDeleteWhy did I not Google this before today... Thanks heeeeeaps buddy :-)
ReplyDeleteIt didn't work for me. My pdf still saved huge. Sorry to be the one to have a problem. I am still happy with the article. :)
ReplyDeleteThank you so much for clearing up this issue - it's been giving me a headache for ages. Your tips worked like a charm and reduced my file size by 75%. Excellent!
ReplyDeleteThe problem is is that every time I make the ai file bigger, then export it as a pdf, each new pdf gets bigger.
ReplyDeleteExample:
AI File - original - 200mb.
PDF Save File - 11.7mb
AI File - 1st edit - 220mb
PDF Save File - 12.7mb
AI File - 1st edit - 230mb
PDF Save File - 13.7mb
AI File - 1st edit - 260mb
PDF Save File - 14.7mb
I have been struggling with this- thank you so much! My printer appreciates it too!
ReplyDeleteIts really very effective tips. The size problem is a common problem for me. Thanks your tips work for me.
ReplyDeleteThis article is very useful for me. I will try urgent because i have struggling with issue two month. Thank you so much for wonderful sharing
ReplyDeleteThanks heaps for this helpful post - saved me lots of time and frustration
ReplyDeleteYou can choose the quality of the file from the drop down list above, and choose press quality which will reduce the file size more than 35% with the unchecked option of add the editable feature for the file.
ReplyDeleteThanks this is working
ReplyDelete80mb to reduce 1mb
thank you!
ReplyDeleteSomething else to try - ensure 'Press Quality' PDF is selected when saving a copy of the file for print - in addition to deselecting 'preserve editing capabilities'.
ReplyDeleteThis reduced my file size by 90%.
The big part of this tutorial is that his first option selected is [PRESS QUALITY] That's a huge space saver. Please update this tutorial to emphasize.
ReplyDeletei want less than 300 kb from 1.0 mb. is it possible?
ReplyDeleteThank you so much for the article.
ReplyDeleteThank you so much.. managed to get my file down from 121MB to 300KB by choosing 'smallest file save' in last pane that comes up-rather than 'standard' .. fabulous 'press quality got it down to 68MB still to big- but helped me find an answer. cheers.
ReplyDeleteFor those struggling with massive PDF sizes still, this is what I have discovered... Save your illustrator file as the "smallest file size" but before hitting Save, on the left click 'compression' then increase the Bitmap image compression to maximum & 300DPI. I have found that to be the winning combination for me! It means photos don't come out blurred/pixelated yet file size is a size you can email. My file size went from 86MG to 5MB.
ReplyDeleteThank you! All amongst the hundreds of google results this was the most simple and effective one!
