Redact PDF (Mask Info)

Permanently hide sensitive data — the text underneath is truly removed.

FreeNo watermarkOffline

Why is it safe? Many sites upload your file to their servers. Not here: everything happens in your own browser. Your file is never sent to the internet and stored nowhere — because it is never received. It even works offline.

How it works (3 steps)

Upload your PDF or photo.
Draw a box over each area you want to hide (auto-detect finds IDs/IBANs).
Tap “Download masked PDF” — boxes are permanent, image-based output.

Tips

Redaction is permanent — the text underneath can’t be recovered.
Auto-detect masks IDs, IBANs and tax numbers in red.
Mask ID and signature areas before sharing a contract.
