How to repair pdf

  1. Choose the PDF that will not open.
  2. Press Repair. The file is sent to the document service, which rebuilds its structure.
  3. Download whatever was recoverable.

Questions

Will it definitely fix my file?
No, and that is worth saying plainly. Repair rebuilds the index and object structure, which fixes a truncated download or a corrupted table. If the page content itself is gone, nothing can invent it back.
Why does this one need a server?
Rebuilding a broken file needs qpdf, which cannot run in a browser. It is the one route where the file does leave your device — it is converted and deleted immediately, never stored.
