Repair PDF
Repair PDF rebuilds a document that will not open, crashes your viewer or shows missing pages. It reads as much of the structure as it can, reconstructs the damaged parts and writes out a clean, valid file. Text and images that survived the damage come back intact, and the result opens normally in any reader.
How to use Repair PDF
- Upload the damaged PDF — even if your viewer only shows part of it.
- Press Repair PDF and wait while the structure is rebuilt.
- Download the repaired file.
- Open it in a fresh viewer and check the pages you care about most.
Repair PDF FAQ
Will everything in my file be recovered?
Most content is, but a badly corrupted file can have unrecoverable sections. Whatever could be read is preserved and the document becomes usable again.
What usually causes a broken PDF?
Interrupted downloads or saves, disk errors, truncated uploads and files copied while a program was still writing to them.
What if repair does not help?
Try opening the original in a different viewer first — the file may be intact but your reader is failing. Otherwise validate the source and regenerate it from the original application.
