Frequently asked questions

Does repairing a PDF cost anything?

No, attempting a repair is free and there's no account to create. Upload the broken file and see whether it can be recovered.

Is my damaged file handled privately?

Yes — the file is processed on our servers only, never shared, and deleted automatically within 2 hours whether the repair succeeds or not.

Can every damaged PDF be recovered?

Not always. The tool rebuilds the file structure and recovers everything that can be salvaged, which fixes many PDFs that won't open — but severely corrupted data may be beyond repair.
