Image Blur and Pixelate Tool
100% PrivateImage ToolsBlur or pixelate a whole image or just a selected region before you share it.
Runs entirely in your browser. Your input is not uploaded to Ovatly or anywhere else.
- 1Choose the image you need to make safe.
- 2Leave the scope on region, then drag a box over the face, plate or text to hide; or switch to the whole image.
- 3Choose pixelate for a hard, irreversible mosaic, or blur for a softer cover, and set the strength.
- 4Apply the effect, check that nothing readable survives, and download.
On a 1600 x 900 car photo, drag a box around the plate, say 280 x 140 px, choose pixelate at 14 px blocks and apply: the plate area becomes a mosaic of roughly 20 x 10 chunky blocks, far too coarse to read characters from, while the rest of the photo is untouched.
- Pixelation at a strong setting is effectively irreversible. Light blur is not: faces and text under a weak blur can sometimes be guessed or enhanced, so for real privacy use strong pixelation and check the result zoomed in.
- The region editor covers one rectangle per pass. Apply, then run the result through again for a second area, or choose the whole-image scope.
- Blur uses the browser's canvas filter; a few older browsers lack it and the tool then tells you to use pixelate, which works everywhere.
Pixelate, at a block size of 14 px or more. Blur smears detail but keeps shapes and colors that can leak information; a coarse mosaic destroys the detail outright.
About this tool
The Image Blur and Pixelate Tool hides sensitive parts of an image before you share it: faces, number plates, names, addresses and screens. Draw a box over exactly what must not be seen and pixelate or blur just that region, or apply the effect to the whole picture; everything outside the box stays pixel-perfect.
