Hide names, addresses, IDs, QR codes, and other details before sharing screenshots, photos, or scanned document images.

Mask only the necessary areas before sharing support screens, admin panels, statements, or photo evidence.

Files are processed in the browser and are not sent outside RedactPen.

Use solid fill when information must be clearly hidden, or choose blur or mosaic when a softer visual result is preferable.

Images can be exported as PNG, JPEG, WebP, or PDF.

After export, open the output and confirm that no sensitive details remain visible.

Small text, background details, and identifiers near the edge of a screenshot are easy to miss.
