Privacy by default

MaskBeforeShare processes images on-device, exports a new PNG without original EXIF metadata, and works without accounts, uploads or server storage.

Ad-ready without layout jumps

Ad containers reserve space before any network script is added, so revenue integrations can be enabled later without hurting the editor flow or Core Web Vitals.

Built for quick review

Automatic detection is best-effort in-browser. The final call stays human: toggle, add and remove masks before saving the anonymized image.

Privacy-respecting ads. The app works without cookies. Optional ad or analytics services should load only after consent and configuration.
