How PDF Repair Works
This tool attempts to recover your PDF by parsing and re-saving the document structure using pdf-lib.
  • Reads the raw file bytes and attempts to load the PDF structure
  • Skips over corrupt objects and recovers valid pages
  • Rebuilds the cross-reference table and file trailer
  • Saves a clean copy with repaired structure
Works best on: PDFs with damaged headers, broken cross-references, or incomplete writes. Severely corrupted files with destroyed page data may not be fully recoverable.
Privacy
Your file never leaves your device. All processing happens locally in your browser using JavaScript. No data is uploaded to any server.

Frequently Asked Questions

This tool can fix PDFs with damaged headers, broken cross-reference tables, incomplete file trailers, and corrupt object streams. It works by re-parsing the document structure and rebuilding a clean version. It handles most cases where the PDF viewer shows an error but the page data is still intact.
No. The entire repair process runs locally in your browser using JavaScript. Your file never leaves your device and no data is sent to any server. This ensures complete privacy for sensitive documents.
A partial repair means the tool was able to load and re-save the PDF, but had to skip some corrupt objects. The repaired file may be missing images, fonts, or other embedded resources, but the page structure and text content should be recovered.
Repair can fail when the PDF file is too severely damaged for the parser to find any valid structure. This typically happens with truncated downloads, files corrupted by malware, or files that are not actually PDFs. Try downloading the original file again if possible.
In most cases, yes. The tool preserves all recoverable pages, text, images, and formatting. However, if some objects were corrupt and had to be skipped, there may be minor differences such as missing images or font substitutions.
