The short answer
Why use Blur Face?
A manual selection is predictable: drag over the private detail, inspect the preview, and blur exactly that area.
Blur Face focuses on selecting a face area and applying adjustable blur. The selected rectangle is stored as image-relative coordinates, so the preview and original-resolution export cover the same pixels.
The selected file stays in this browser tab and is released when you leave the page. Check every edge of the selected area before downloading. Increase the blur amount until text or facial detail is no longer readable.
What Blur Face does
Open the source photo
Drop, choose, or paste a supported file into Blur Face. Selecting a face area and applying adjustable blur. The source stays on your device; we work on a copy.
Review the detected boxes

Useful controls
