Face blur help

Face Blur detects faces in a still image, applies the same privacy mask to every detected face, and exports the result from your browser.

Common Uses

Use Face Blur before sharing event photos, classroom images, screenshots, or listing photos when people in the image should not be easy to identify.

Supported File Types

Use common browser-readable still images such as PNG, JPG, JPEG, WebP, and BMP. Animated images, unusual files, or images your browser cannot decode may fail or export only a still frame.

Local Processing And Model Download

PixTools does not upload your selected image to a PixTools server for face detection or masking. Your browser may download local face detection model and WebAssembly assets before processing the image.

Automatic All-Face Masking

The tool does not include manual face selection. When faces are detected, the selected Smooth blur or Pixelated mask is applied to all detections automatically.

Missed Faces And False Positives

Face detection can miss small, side-profile, hidden, occluded, low-light, or low-resolution faces. It can also mask something that only looks like a face. Always review the preview before sharing the download.

Downloads

PNG, JPEG, and WebP originals are preserved when your browser's Canvas export supports the format. BMP or unsupported same-format exports fall back to PNG, and the tool shows a note when that happens.

Troubleshooting

If detection or export fails, try a smaller image, refresh the page, use PNG or JPEG input, or switch to a current version of Chrome, Edge, Firefox, or Safari.

Limitations

The current Face Blur tool supports still images only. It does not process video, animated GIFs, webcam input, batches, manual face choices, metadata edits, or server-side detection.

FAQ

Can I choose which faces to blur?

No. Face Blur applies the selected mask to every detected face automatically. Review the preview because detection can miss small, side-profile, covered, or low-quality faces.

Will my download keep the original format?

The tool preserves PNG, JPEG, and WebP when Canvas export supports the original format. Unsupported formats or failed same-format exports download as PNG.

Does PixTools upload my image?

No. The current workflow runs detection and masking in your browser. Your browser may download the face detection model and WebAssembly files needed to run the tool.
