Can every type of PDF corruption be repaired?

Most structural corruption — broken cross-references, incomplete file trailers, damaged object streams — is handled well. Severely overwritten or physically destroyed files may allow only partial recovery, but the tool always recovers the maximum available content.

Will the repaired PDF look exactly like the original?

In most cases yes. Where damage has affected specific pages or elements, those sections may be absent or degraded in the output, but unaffected content is restored intact.

Can I repair a password-protected corrupted PDF?

Yes, if you know the password. You will be prompted to enter it during the repair process. The repair tool does not remove or bypass passwords.

What is the file size limit?

Free users can repair files up to 50 MB. Larger corrupted archives can be processed under a premium subscription.

Is my damaged file kept private?

Yes. The upload is protected by 256-bit SSL encryption and the file is deleted from our servers as soon as your repaired download is ready.

What if the tool cannot repair my file at all?

If the damage is beyond what the engine can reconstruct, you will receive a clear message explaining this rather than a silently empty output. In that case, partial page extraction may be worth attempting.
