About Repair PDF

Most "this file is damaged" errors are about the file's index rather than its content: a cross-reference table with the wrong offsets, a download that stopped early, or a page tree with a dangling reference. The repair reads the objects directly, rebuilds the catalogue and page list where needed, drops what cannot be parsed and writes a fresh, correct index.

If even that fails, the pages can be rescued as images - a last resort that saves what can still be seen but loses selectable text. It cannot invent content that is not in the file.

How to use it

  1. 1Add the damaged PDF.
  2. 2Leave the image rescue option on as a fallback.
  3. 3Run it - the result note says what was fixed.
