Why Choose This Face Blur Tool?
face<br>Blur Faces Automatically<br>Detect faces in a photo and apply blur only to selected face masks, not the whole image.
gesture<br>Fix Faces with Lasso<br>Draw a manual face mask when detection misses someone or when you need tighter control around a face.
lock<br>Private Face Redaction<br>Face detection, mask editing, blur preview, and PNG export run locally in your browser.
Face blur workflow<br>Detect faces, blur selected faces, and export safely
Blur & Unblur AI is built for quick face privacy edits before publishing screenshots, group photos, event images, profile shots, school photos, or social posts. Start by loading a JPG, PNG, or WebP file. The editor draws the photo to an HTML5 Canvas, runs face detection in the browser, and creates editable masks for each detected face.<br>In Face Blur mode, the blur effect is clipped to selected face regions instead of softening the entire image. If automatic detection adds a wrong box, remove that selection. If it misses a face, switch to Lasso and draw a custom face mask by hand. The result is a targeted face blur workflow for hiding identities while keeping the rest of the image useful.<br>Face Unblur and Full Blur remain available as extra modes, but the primary job is simple: blur faces online with enough control to handle real photos. The strength slider updates the Canvas preview immediately, and the download action exports the final face-blurred PNG without guide boxes, dashed frames, handles, or editor-only overlays.<br>Blur faces nowRead the privacy noticeContact on GitHub
Local Face Processing<br>Your face photo is decoded, edited, and exported with browser APIs on your device. The face blur editor does not send the source image to an upload or processing server.<br>Face detection creates editable blur masks, while Select and Lasso let you correct the affected face regions before downloading a clean PNG.

Use cases<br>Practical face blur tasks
Public sharing<br>Blur faces before publishing street photos, school events, meetups, screenshots, testimonials, or community galleries. Face blur keeps the background readable while reducing the visibility of people who should not be identifiable.
Selective edits<br>Use Select mode when only one face in a group should be blurred. Remove false detections, toggle face masks, and combine automatic face detection with a manual lasso region for tighter control.
Fast local workflow<br>The tool is useful when you need a quick face blur workflow without uploading a private source image to a cloud editor. Review the canvas result, adjust blur strength, then download a clean PNG for sharing.
Frequently Asked Questions<br>Is this mainly for blurring faces?<br>expand_moreYes. Blur & Unblur AI is focused on face blur first: detect faces, select the faces you want to hide, adjust blur strength, and export a clean PNG.<br>What if face detection misses a face?<br>expand_moreSwitch to Lasso mode and draw around the missed face. That hand-drawn region becomes a face mask and can be blurred like an automatically detected face.<br>Can I remove a wrong face detection?<br>expand_moreYes. In Select mode, remove false detections or turn individual face masks on and off before downloading the final blurred image.<br>Can I blur the whole photo too?<br>expand_moreYes, but full photo blur is secondary. The main workflow is face blur, while Full Blur is available when the entire image or background also needs to be obscured.<br>Are my face photos kept private?<br>expand_moreYes for this implementation. The image is decoded, face masks are created, and the blurred result is rendered with browser APIs locally; no upload endpoint is used.<br>Which browsers and image sizes are supported?<br>expand_moreBlur & Unblur AI works best in current Chrome, Edge, Safari, and Firefox releases with JavaScript and...
