zeroNet Redact

Redact before you share. AI finds phone numbers, IDs and card numbers in photos & PDFs — cover them in one tap with mosaic, blur or blackout. 100% offline

ZeroNet Redact is a fully offline privacy redaction tool. Before you post, submit, or share a photo or PDF, cover up what shouldn't be seen — safely.

AI-POWERED DETECTION The built-in offline text recognition engine automatically finds phone numbers, email addresses, ID numbers and bank card numbers in your photos and PDFs. Review each finding one by one, or redact them all in a single tap. Multi-page PDFs are handled page by page.

PRECISE MANUAL REDACTION Just draw with your finger. Pinch to zoom for small text, choose mosaic, blur, solid black or colored block effects, pick from three brush sizes, and undo/redo freely. Move or resize applied redactions any time before export.

REAL PRIVACY, BY DESIGN • 100% offline: no network requests, no account required — your files never leave your device • Encrypted at rest: imported originals are stored with AES-GCM encryption, protected by a password plus Face ID / Touch ID • Snapshot protection: the interface is covered automatically in the app switcher, so nothing leaks on screen

ORGANIZED FILES Sort originals and redacted results into custom groups. Redacted files can be shared or exported directly, while your originals stay untouched for re-editing.

FREE & PRO The free version exports up to 3 images and 3 PDFs per day. A single one-time purchase unlocks unlimited exports — no subscription, no ads.

Perfect for: hiding order numbers on receipts, masking details on ID photos, removing contacts from chat screenshots, covering signatures and account numbers in contract PDFs.
