Attempt a conservative structural rebuild without uploading a potentially sensitive document.
Fresh rebuilt copy
Clear repair receipt
Know the limits
Local does not mean unlimited.
Browser processing avoids an upload workflow, but available memory, PDF structure, digital signatures, and the settings you select still matter.
- Unrecoverable or severely truncated files cannot be restored.
- Repair does not recreate missing content or fix incorrect visual design.
- Rebuilding invalidates signatures and may discard malformed structures.

Clear answers
PDF repair questions.
Can it repair every broken PDF?
No. It can reconstruct recoverable structure, but bytes that are absent or irreparably damaged cannot be recreated.
Does repair change the file?
Yes. It creates a new rebuilt copy and leaves the original untouched.
Is repair the same as malware cleaning?
No. This is structural recovery, not malware analysis or complete sanitization.
