What Is the Face Blur Tool?

The Face Blur tool automatically detects every face in a photo and applies a smooth Gaussian blur to each one. It is ideal for anonymizing photos before publishing them online or sharing them publicly.

The detection model and all processing run locally in your browser using WebAssembly, so your images stay completely private.

How to Blur Faces

Follow these steps:

  • Drop or upload a photo containing faces.
  • Adjust the blur strength slider if needed.
  • Click Blur Faces and wait for the AI model to process the image.
  • Download the result as a PNG file.

Tips

  • The model detects front, side, and profile faces well.
  • Use well-lit photos for the most reliable detection.
  • A blur strength around 25% looks natural in most cases.
