What it does
- Brush a blur over one region, freehand
- Or blur the whole image with a slider
- Set radius and strength independently
- Runs on the graphics card where the browser allows it
Blur is not redaction
A light blur over text can sometimes be reversed, because the information is still in the picture, just smeared. For hiding a background or softening a distraction it is the right tool. For a password, a plate or an address, use pixelation with large blocks or a solid box instead.
On the graphics card
Where the browser exposes WebGPU, the whole-image blur runs there, which makes a large radius on a large photo effectively instant. Where it does not, the same code runs on the CPU with SIMD. You do not choose; it picks whichever is present and the result is identical either way.
No account needed
Every tool that runs on your own machine works logged out, with nothing to sign up for. Signing in adds sync across your devices and share links; Pro adds the passes that need a server. The no-upload page draws the line between the two, and Architecture shows it table by table.
