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 file is uploaded over an encrypted HTTPS connection, converted on our server and streamed straight back to your device. Each request runs in its own isolated workspace that is deleted the instant the result is returned, so nothing is ever stored or shared.
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. Unlike our browser-based tools, the Repair PDF runs on our secure server because it needs professional desktop-grade software to do the job well. Your file is processed in an isolated workspace and deleted automatically the moment the result is sent back — nothing is stored, logged or shared.
Is it free? Is there a watermark or size limit?
It is completely free with no sign-up and no watermark. Files up to 100 MB are supported per conversion.
