What version of Acrobat do I need?

None. Adobe Acrobat is no longer required as of PDF Snake version 6.

Are there any limitations?

PDF Snake cannot impose documents that are encrypted. Adobe Acrobat allows the creator of a PDF document to specify the exact permissions for that document. If modification is not allowed, then PDF Snake can't impose it.

PDF Snake cannot impose files that are larger than 1 GB. If you see memory errors with large files, try using the Firefox browser. It can handle larger files than Chrome, Edge, or Safari.
