Hi there 

 

We hope you are doing well. Thanks for reaching out. We are sorry for the trouble you are experiencing.

 

As described, it works for some PDFs but not for others. It seems to be an issue with the PDF file. Would you mind sharing the PDF file in question so we can check it at our end? 

 

Also go through the help page https://helpx.adobe.com/acrobat/using/optimizing-pdfs-acrobat-pro.html and see if that helps.

Bump.

 

I am just trying to reduce the size of a file that is only 34.1MB, and it crashes.

The only solutions i have found are these:

  • use a third party website (if you are using the free option they will keep your files for 24 hours and that is a no-no in my case).  
  • use the online Adobe compression tool. I've found that it works about 60% or 70% of the time: https://documentcloud.adobe.com/link/acrobat/compress-pdf/ 

That is my only choice and I have been getting decent results.

Good luck!

Same here

 

tried reducing file size of 200mb doc and just keeps crashing.

And guess what?  I downloaded the same 130MB file into an old computer that has Acrobat Pro X. 
Saved as Reduced PDF and it took about 4 minutes to produce a 68MB file.  No errors. No crashing.  So this means that in order to reduce the size of my big files I am going to have to use an unsupported version in another computer???? 
Supper disppointed.

Brand new installed program, Adobe Pro 2020 for Windows 10. 
The very first thing I tried was reducing the size of a file and ... crash crash crash crash.  I have separated the file into two, and it did it again. This is so obnoxious!!!

I've also been having trouble optimizing databooks recently, and I noticed it was just recent submissions from one vendor. I split one of the databooks up, and optimized one piece at a time. I was able to optimize some but not one piece. I split the problematic part again into several files, and was again able to optimize all but one. I finally narrowed it down to one page that the vendor recently added to their databook template. I don't know why this one page causes the optimization to fail, but I removed it and was able to now optimize the whole file, and then added the one page back into the optimized PDF. I then tried optimizing another similar databook. I removed the page in this second databook that caused the trouble in the first databook, and was able to optimize and add the page back just fine. So now I know what page to avoid optimizing. I wish Adobe would throw some sort of exception with some helpful error code instead of just crashing the program with no information though.

So for those having trouble with optimizing your PDFs, do the files that crash the optimization have anything in common? Are you dealing with a lot of files that have a lot of similar repeat information? Try optimizing a totally random PDF that has nothing in common with the typical PDFs that crash and see if that works. Split a problem file up into multiple smaller files and check if there is just a page or small set of pages in the mix that may be causing the trouble. You may then find that the problem page is also part of the other files giving you trouble and be able to optimize your files and avoid the crashing. Hopefully this helps someone.

I've been having the same problem for a long time, now.  I did all the suggested fixes and nothing.  (Side complaint) I wish there was an alternative to adobe, any time I try to use a feature the app prompts me to pricing for an upgrade and yet I can't do this simplest function with what I'm paying for.  It is totally unclear what features are included for 180$/year.
