When combining files I have repeated conversion failures, even when converting only two files, how do you fix this issue

Hi 061walter,

How large are the files that you're trying to combine? There's a 100 MB file-size limit per file. I'm also curious whether there is any security applied to the files that you're trying to combine. (PDF Pack won't combine files that are secure, password protected, 3D, or part of a PDF Portfolio.)

Are you able to narrow down the problem to a specific file or files? Or does the problem happen consistently, regardless of the files you try to combine?

For starters, please clear the browser cache and try again, or try using a different, supported, web browser: System requirements | Acrobat.com

If that doesn't do the trick, please let me know and we'll take it from there.

Best,

Sara
