When to blur an image
Common uses
Blurring softens detail across the whole image. It's used to create gentle backgrounds for text overlays, to set a mood, to de-emphasize a busy background, or to lightly obscure a screenshot before sharing.
For hiding sensitive details specifically (faces, names, plates), a strong blur helps, but pixelation is usually a more deliberate-looking censor — see our pixelate tool for that.
Three strengths
Light blur keeps the subject recognizable with a soft, dreamy feel. Medium is good for backgrounds behind text. Strong heavily diffuses the image for abstract backgrounds or light censoring.
Private and instant
The blur is rendered on a canvas in your browser using the native CSS filter, so it's fast and your photo is never uploaded.
Frequently asked questions
Can I blur just part of the image?
This tool blurs the whole image. To blur a region only, crop that part, blur it, and place it back over the original in an editor.
Is blur good for censoring sensitive info?
A strong blur helps, but pixelation is harder to reverse and looks more clearly censored. For truly sensitive data, crop it out entirely.
Will the resolution change?
No — the output keeps your original image dimensions.
Is my image uploaded?
No. Everything is processed locally in your browser.
