## Overview (en)

Blur faces applies a blur to a rectangle you define by its left and top position, width and height in pixels. The blur radius ranges from 2 to 100 pixels, with a default of 18. There is no automatic face detection, so you choose each region yourself and should check the whole image before sharing it.

## Supported tasks (en)

Choose the region to blur manually. Automatic face detection is not offered, so review the entire image for identifying details.

## Steps (en)

1. Choose a source file. If the tool accepts multiple files, arrange them in the order you want.
2. Set left (px), top (px), selection width (px), selection height (px), blur radius.
3. Run blur faces, review the output, then use the available copy or download controls.

## Settings

- Left (px) (en; key: x; type: number); minimum: 0; maximum: 10000
- Top (px) (en; key: y; type: number); minimum: 0; maximum: 10000

## Questions (en)

### Does blur faces detect faces automatically?

No. You enter the region to blur using pixel coordinates. Review the entire image for other identifying details such as name tags, license plates or reflections, because only the selected rectangle is changed.

### How strong should the blur be to hide a face?

The default radius is 18 pixels and the maximum is 100. Larger values remove more detail, but blurring is not guaranteed anonymization, so zoom in on the result and increase the radius if features remain recognizable.

### Can I blur several areas of the same photo?

Each run blurs one rectangle. To cover more areas, download the result, load it again and blur the next region. If you select several files, the same rectangle is blurred in each and the outputs come as a ZIP.
