Frequently asked questions

How do I blur part of an image?

Upload your image, drag a box on the preview over the area you want to hide, then raise the strength slider until the detail is unreadable. Add as many boxes as you need, then download.

Is my photo uploaded to a server?

No. The image is loaded into a canvas element in your own browser and processed on your device. Nothing is transmitted, stored, or logged anywhere.

Can the blur be reversed?

No. The effect is flattened into the exported pixels, so the original detail underneath is gone from the downloaded file. This is unlike a document where a shape sits on a movable layer.

Which mode should I use — blur, pixelate, or black box?

Blur suits backgrounds and faces. Pixelate is stronger for text like plates and account numbers. A solid black box is the most secure, since it replaces the pixels entirely.
