Blur or pixelate?

Soft blur makes smooth, out-of-focus pictures. Pixelate makes large squares, which is a clear way to hide text or details.

Hiding a face only?

This tool blurs the whole picture. To hide only faces and keep the rest sharp, use Blur Face.

Is the blur reversible?

Strong blur and pixelation cannot be undone, but a light blur may still leave readable shapes. Use a high strength for private details.
