- Drop the image.
- Pick the box by eye and drag it over the part.
- Press Blur and download.
What happens to your file
The box you drew is cut out in the picture’s own pixels, a Gaussian blur whose radius is a per cent of the shorter side is applied to that piece alone, and it is put back exactly where it was. Nothing outside the box changes — the report says the pixels used.
A face at the heaviest setting is not recognisable, but a blur can be partly undone by a determined analyst; for a plate or a name, Pixelate part of an image at a coarse block removes more.
Questions
Several faces?
One box per run today; run it again on the result for the next. Several boxes at once is on the list.
Is it enough to hide someone?
For a social post, yes at Heavy or Unrecognisable. For anything that matters, pixelate coarsely — or crop them out.
