Repair PDF
Attempt to recover and rebuild a damaged or corrupted PDF file.
About this tool
A PDF that refuses to open after an interrupted download or a disk error is not necessarily lost. Repair PDF parses the damaged file in a tolerant mode, salvages every readable page, and rebuilds them into a fresh, standards-compliant document.
Recovery success depends on how much of the file structure survived, but in many cases most or all pages can be rescued — without sending your broken file to anyone.

Frequently asked questions
Can every damaged PDF be repaired?
No tool can guarantee recovery. If the core structure is intact, most pages are usually recoverable; severely truncated files may be beyond repair.
What causes PDF corruption?
Interrupted downloads or transfers, disk errors, buggy generators, and email systems that modify attachments are the most common causes.
Is my damaged file safe here?
Yes. The recovery runs entirely in your browser, so your file — damaged or not — never leaves your device.
