Try to fix a corrupt or “won’t open” PDF and recover as many readable pages as the file still contains.
PDFPeach attempts a local repair in your browser, then shows how many pages came through so you know what was salvageable before you download.
How to repair a PDF
- Drop the damaged PDF into PDFPeach.
- Run repair and review the recovered page count.
- Download the repaired PDF if pages were recovered.
Why repair PDFs with PDFPeach
Downloads get truncated, email gateways mangle attachments, and old exports sometimes leave files that readers refuse to open. A local repair often restores enough for a viewer to open the file again — without uploading sensitive content to a third-party fixer.
PDFPeach is free, runs in the browser, and keeps processing on your device.
When to repair a PDF
- A PDF errors on open or shows as damaged in your reader
- A download was interrupted and the file is truncated
- Merge or optimize tools reject a file that used to work
- You want a best-effort recovery before re-requesting the original
What repair can fix
It helps with many “won’t open” or damaged PDFs by rebuilding what can still be read from the file.
What repair cannot do
It cannot recreate page content that is missing from the file. Severely overwritten or empty files may recover few pages — or none.
Tips
Results vary with how much of the file survived. After a successful repair, you can Optimize or Unlock (if still encrypted and you know the password) as needed.
Frequently asked questions
Will repair restore every page?
Not always. Mildly damaged files often recover completely; severely truncated files may yield only some pages, or none.
What kind of damage can this fix?
Many files that refuse to open or report as corrupt. Missing page content cannot be invented.
Should I repair before unlock or optimize?
If the file won’t open or other tools fail, repair first. Then unlock (with a known password) or optimize the recovered copy.
Are my files uploaded?
No. Repair runs entirely in your browser on PDFPeach — free, with no account required.
