Frequently asked questions
How do I blur an image online?
Drop your image in, drag the blur strength slider until it looks right in the live preview, then click Blur and download the result. You can blur several images at once with the same strength.
Can I blur just the background?
This tool blurs the whole image uniformly. To obscure only part of a photo — such as a face or a licence plate — use the Pixelate Image tool, or crop the region first.
Are my photos uploaded?
No. The blur is applied on a canvas in your browser, so your images never leave your device.
