Does Blur & Unblur AI send my photo to a server for processing?

No—face detection and editing run locally in the browser using Canvas and client-side JavaScript.

Can the tool blur only faces instead of the entire photo?

Yes. It supports face-only blur so blur is applied to selected face masks rather than the whole image.

What if face detection draws the wrong box or misses a person?

Users can remove wrong detections and use a lasso to draw a manual mask around faces that were missed or need tighter control.

Product Overview

Blur & Unblur AI is a free online face blur and unblur tool that performs private image editing locally in the browser. It detects faces automatically, lets users correct face masks (including removing false detections or using a lasso to cover missed faces), and applies blur with adjustable strength.

The editor supports face-only blur or full-image blur, and can unblur selected face regions. When the result looks right, it exports a clean PNG without guide boxes or editor overlays, using browser Canvas and client-side JavaScript so the source photo isn’t sent to an upload or processing server.

Key features

Automatic face detection to blur only selected face masks rather than the whole image
Face mask correction tools to remove wrong detections and refine boundaries
Lasso masking to cover missed faces or tighten control around a specific person
Adjustable blur strength with live blur preview during editing
Face-only blur or full photo blur modes, plus an unblur option for selected regions
Local browser processing with clean PNG export (no server upload, no editor overlays)

How Blur & Unblur AI works

1
Upload image for detection
The user loads a JPG, PNG, or WebP photo into the editor so faces can be detected in-browser.
2
Adjust masks and blur strength
The user removes false detections or draws lasso masks for missed faces, then adjusts blur strength with a live preview.
3
Export clean PNG result
The user selects the desired blur/unblur mode and downloads a clean PNG without guide boxes or editor overlays.

Use cases

A user preparing screenshots for sharing can blur faces while keeping the rest of the image clear, then export a clean PNG for posting.
After automatic detection misses someone in a group photo, a user can draw a lasso mask around the missed face and adjust blur strength until it matches expectations.
A user wants to reverse blur on a specific region (e.g., a face that was blurred too broadly) by unblurring selected areas and re-exporting the corrected PNG.

Who is it for?

Blur & Unblur AI benefits people who need quick face privacy edits for screenshots, group photos, and social posts—especially when they prefer local, in-browser processing. It’s also useful for designers or developers handling redaction workflows that require controllable masks and export-ready images.
