Frequently Asked Questions

Can the tool recover deleted PDF content?

No. It attempts to repair the available file structure and cannot restore text or images that are no longer present in the document data.

Will the document content change?

The tool attempts to preserve the existing content while rewriting the document structure. You should still review the resulting file carefully.

What should I do if the repair fails?

Try another backup of the file or export it again from the original application. Severe corruption may not be repairable automatically.

Do I need to install any software?

No. The tool works online directly through your web browser.
