How large can my corrupted PDF file be?

Our system supports repairing PDF files up to 100MB, making it ideal for large reports, presentations, technical publications, and scanned documents.

Can you repair password-protected or encrypted PDFs?

Currently, our PDF repair tool does not support encrypted or password-protected PDFs. You’ll need to remove the password first and then upload the unlocked file for repair.
