Expectations for PDF repair.

DocMint uses encryption for transfers when server processing is required and automatically deletes files after processing per our retention policy.
Why do PDFs become corrupted?
Incomplete downloads, disk errors, or bad merges can damage the file structure.
Should I try repair before converting?
Yes. Fixing structure first often improves conversion success.
