How to Repair PDF

The tool uses FPDI to open the source file and read its page structure. Rather than trying to fix the file in place, it walks through the document page by page, importing each one as a template into a brand-new PDF.

Pages that are readable are copied across intact, preserving their original size and orientation; if an individual page's internal structure is too corrupted to import, that specific page is skipped and logged, while the rest of the document continues to be recovered.

The response reports exactly how many pages were successfully recovered versus how many failed, so you know upfront whether the repair was complete or partial before you rely on the output file.

Safe & Secure

Your files are uploaded over an encrypted (SSL) connection. We don't store, read, or share the contents of your files — they're processed to generate your result and are not retained on our servers afterward.

Who Uses Repair PDF?

  • Recovering a PDF that won't open after an incomplete download or a corrupted file transfer.
  • Fixing a PDF that displays garbled content or won't render correctly in some viewers.
  • Salvaging an old file that has become partially corrupted in storage.

Limitations to Avoid

  • Assuming every corrupted file is fully recoverable — repair can often restore a file to a usable state, but severely damaged files may only be partially recoverable.
  • Not keeping the damaged original — if repair doesn't fully succeed, having the original preserved means you can try a different recovery approach.

Tips for Best Results

  • If you have the source the PDF was created from (a Word doc, a scan), regenerating the PDF from scratch is often more reliable than repairing a badly damaged file.

Privacy Commitment

We respect your privacy. All files are processed securely and are never sold, shared, or used for anything beyond generating your result.

Frequently Asked Questions

Will this always fully fix my PDF?
Not always — repair works by re-importing whatever page structure it can still read. If a page's internal data is too severely damaged, that page is skipped rather than guessed at, and the response tells you exactly which pages were recovered.
What kinds of PDF problems does this fix?
It's effective against structural corruption — broken cross-reference tables, incomplete downloads, or truncated files — that prevents a PDF from opening normally, since rebuilding the page objects from scratch bypasses the damaged parts of the file.
Can this repair a password-protected PDF?
No — the file needs to be readable without a password first. Use the Unlock PDF tool beforehand if the damaged file is also encrypted.
What's the file size limit for repair?
Up to 100 MB per file, which is higher than most other tools here since damaged PDFs sometimes carry extra bloat from the corruption itself.
