Your privacy matters

FAQ
Is blur processing private?
Yes. Patches are generated locally in your browser.
Can I blur circles?
Ellipse and freeform options are on our roadmap; rectangles cover most cases today.
Does blur work on HDR images?
Yes, as long as the browser can decode the format.
Will recipients reverse the blur?
Heavy pixelation is safer for high-sensitivity content.
