All processing happens locally on your device — no images are uploaded to any server.

Perfect for privacy-conscious users who need to hide identities in screenshots, group photos, event images, or social media posts before publishing.
What is Blur & Unblur AI?
Blur & Unblur AI is a free online face blur tool that runs entirely in your browser. It uses face detection technology to automatically find faces in uploaded photos, then lets you blur selected faces, unblur them, or blur the entire image. The tool also includes a lasso tool for manually selecting faces the detector might have missed. All image processing happens locally on your device via HTML5 Canvas — no files are uploaded to any server, making it fully private and secure for sensitive content.
