Frequently asked questions

Can every broken PDF be repaired?

It depends on the corruption level. If critical file sections are missing, recovery may be partial, but the tool will extract what is possible.

Will repairing change my content?

The tool tries to rebuild the file structure without altering any page text or images.

Are my files uploaded to repair them?

No. Rebuilding is done client-side in browser memory.
