i've used the reduce file size feature for large PDF files hundreds of times in the past, with no issues.

 

today i tried it with a 17mg file and it mangled some of the fonts throughout, replacing them with XXs (see attached). all of the fonts are embedded in the original PDF.

 

anyone have this happen and found a solutions? thanks!

++Edited Reply, fixed some typos

 

Were all of these other files (that you were able to reduce in the past)  also over the 10MB file size?

i don't remember the exact sizes, but i've definitely worked on large PDFs to reduced their size (for web or email). 17 mg doesn't seem that large to me...

 

 

i just noticed that acrobat updated my app today...i wonder if that's an issue....

Hi,

I am sorry to hear about the issue you are facing with PDF Optimize. Can you share the culprit files with me to investigate on the issue?

Also, can you please mention the details of the operating system you are using.

Thanks,

I just experienced something similar today using "reduce file size" functionality - letters of a word are missing so that the word has white space in the middle and is unreadable. My original file size was 18mb and it was reduced to 1mb. I tried the function via the main file menu option as well as via the "save as" option, just in case. Same outcome. Would greatly appreciate trouble-shooting help!

Try to use "Optimized PDF" instead of "Reduce File Size".

You must know that "Optimized PDF" using the "Standard" preset do exactly the same optimization that "Reduce File Size".

Pay particular attention to the "Fonts" panel, which allows you not to remove any.

Thank you for the suggestion! I tried using "Optimized PDF" with "standard" settings and I had the same outcome - letters missing in the PDF. I'm on a tight deadline to deliver this file, so I'd be so grateful for any other suggestions.

You can private message me the shareable link of the file. Also, the win7 you are using is OS 32 or 64 bit?

I suspect the original PDF has some unembedded fonts, you may be able to fix this by re-creating the PDF and adjusting the settings to embed the fonts, or running an Acrobat preflight fixup (Tools> Print Production> Preflight> Fixups) to embed the fonts before trying to optimize. If that doesn't help, try the next preflight on the list Fix potential font problems.
