What can Repair PDF fix?
Repair PDF can recover some structural problems that prevent a PDF from opening or being read correctly. Whether a file can be repaired depends on the type and extent of the damage.
What cannot be recovered?
Repair cannot recreate information that is missing from the file. Severely truncated PDFs or files with missing page data may remain unrecoverable. Encrypted PDFs are not supported, and successful recovery is not guaranteed.
Limits and processing
Input files can be up to 25 MB. Repaired output is limited to 25 MB and 500 pages. Repair PDF uses temporary server processing; the uploaded input is removed after processing and the result remains available temporarily for download until expiry.
