Frequently asked questions
Does this work on all corrupted PDFs?
Papiral can fix many common corruption issues — invalid cross-reference tables, missing objects, and encryption flag mismatches. Severely truncated or physically damaged files may not be recoverable.
Will the repaired PDF look the same?
In most cases, yes. The repair process reloads the document structure and re-saves it cleanly. Content, fonts, and images that are intact in the original are preserved.
