Blur Image
Apply a smooth Gaussian blur or a pixelation effect to entire images — to create soft backgrounds, low-detail placeholders or to hide everything in a screenshot before sharing it.

How it works
Blur uses the browser's Gaussian blur filter; pixelation shrinks the image to large blocks and scales it back up without smoothing. Strength scales with image size so results look similar on small and large images.
To hide sensitive information permanently, pixelation or a solid box is safer than a light blur, which can sometimes be partially reversed.
Examples
- Website background
- Blur a photo strongly to use it behind white text.
- Screenshot
- Pixelate a whole chat screenshot to show its layout without its content.
Common uses
- Background images
- Placeholders and previews
- Hiding content in screenshots

Frequently asked questions
Can I blur only part of the image?
Not yet — this tool blurs the whole image. Crop the area first if you only need a part.
Is blurring secure for passwords or faces?
Use strong pixelation; light blurs may be partly reversible.
