Questions

What kind of damage can it fix?

The most common kinds: a wrong or missing cross-reference table (the index that tells apps where each part of the file is), a missing header, a lost catalog or page tree, and files that were cut off during a download or copy. It reads every object it can find and writes a clean file around them.

What can’t it fix?

Content that isn’t in the file any more: missing pages of a cut-off file, or pictures whose data was overwritten. Newer PDFs that pack their pages into compressed object streams can’t be recovered if the part holding the page list is missing. The tool says exactly what it recovered, and never pretends a file is fixed when it isn’t.

Is a password-protected PDF supported?

Not when it is damaged: decrypting needs the file’s structure intact. Repair an unprotected copy if you have one.

Are my PDFs uploaded anywhere?

No. Your PDFs are opened and processed on your device, and the results are saved straight back to it. Nothing is uploaded. How to check.

Is it free? Do I need an account?

It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
