ScreenshotRedactionBlur

Coverstamp is a fast, fully offline redaction tool for the screenshots you're about to share — cover phone numbers, addresses, chat messages, or license plates before anyone else sees them.

Draw freehand or drop a quick circle or rectangle over anything sensitive, then blur or pixelate it with an instant preview — no waiting, no uploads, no accounts. Every redaction happens on your device.

Save a redaction layout as a pattern and apply it to every screenshot that shares its exact size in one pass — ideal for redacting a whole folder of chat exports or statements without repeating the same drag every time.

A private on-device library keeps your redacted screenshots organized and ready to re-export or share, and hardware keyboard shortcuts make repeat edits faster.

Included: freehand and shape drawing, blur concealment, single-image export and share. Coverstamp Pro adds: pixelate style, batch redaction across matching screenshots, and full-resolution clean export.
