Repair a corrupt or damaged PDF
This PDF repair tool tries to recover a damaged or corrupt PDF by rebuilding its internal structure and cross-reference table with qpdf on our server. It can bring back files that won't open or show errors.
When to use it
- Recover a PDF that won't open or shows an error.
- Fix a file damaged by an interrupted download or transfer.
- Rebuild a PDF a viewer reports as corrupt.
Private & secure
Your damaged PDF is rebuilt with qpdf and Ghostscript on our server to recover its structure. The upload is encrypted, the repair runs in a disposable workspace, and both files are wiped the moment the fixed PDF is returned.
Frequently Asked Questions
Can every broken PDF be repaired?
Not always. This tool rebuilds a PDF's structure and cross-references, which fixes many common problems, but a severely truncated or overwritten file may be unrecoverable.
Will repairing change my content?
It only rebuilds the internal structure; it doesn't alter the visible content of pages that are intact.
Are my files uploaded to a server?
Yes. Rebuilding a corrupt PDF needs server-side tools like qpdf, so the file is uploaded for the repair. It is isolated and removed once the recovered file is sent.
Is it free? Is there a watermark or size limit?
Yes — free, no sign-up, and no watermark. Damaged PDFs up to 100 MB each are accepted.
