HideFaces is a browser tool that instantly detects and hides faces in photos while keeping your images private. Everything runs client-side in your browser so photos never leave your device. You can pixelate, blur, or cover faces with emoji stickers, clean EXIF metadata like GPS and camera info, process image batches, and add custom watermarks. It works on iPhone, iPad, and Android without installing an app, and offers upgraded exports and API access for power users.
