Terms of use

Manual masking scope

The tool replaces selected image rectangles with opaque black pixels in a newly encoded PNG. It does not identify private content, certify anonymisation, redact documents or videos, or guarantee that all sensitive details have been covered. Inspect the complete exported image and share only material you are permitted to share.

Supported files and limits

PNG, JPEG and WebP up to 20 MB, 8,000 pixels on either edge and 16 million pixels total are accepted. One decoded still image is processed; animation, documents, SVG, GIF, HEIC and remote image URLs are outside scope. Up to 100 masks and 30 Undo states are supported. Whole-pixel bounds are required for coordinate entry.

Your files

There is no autosave or cloud recovery. Loading a new image resets edits. The inventory is a text coordinate report, not an editable project backup. Saving a masked PNG does not delete or overwrite the original. Review and manage the exported file separately.

Availability

The service is free and provided as available without a promise of uninterrupted operation or fitness for a particular disclosure. Nothing limits rights that cannot lawfully be limited. Do not upload malicious files or use the tool to misrepresent evidence or permissions.
