Repair PDF

Also known as: fix corrupted pdf, repair damaged pdf, recover pdf file

Recover a damaged or corrupted PDF that will not open or shows errors.

FAQ

Is my file uploaded?
Yes. Repair needs an engine that cannot run in a browser, so the PDF is sent to our server. It is processed and deleted immediately after — never stored, logged, or backed up.
Can every PDF be repaired?
Files with a broken cross-reference table, truncated endings or junk before the header usually recover fully. Content that is itself missing or overwritten cannot be restored, and password-protected PDFs need unlocking first.
Is there a size limit?
PDFs up to 25 MB can be repaired.
