Blur a PNG
Apply a smooth Gaussian blur to an image — pick how strong, drop your files, and download. It runs entirely in your browser, so nothing is uploaded, and transparency is preserved. Good for soft backgrounds, privacy blurring, or a frosted-glass effect behind text.

Picking a radius
- 1–3 px — a gentle softening, still recognisable.
- 5–10 px — a clear blur, good for backgrounds behind text.
- 20 px and up — heavy, abstract; use for a colour-wash effect.
A note on privacy blurring
A blur can make faces or text unreadable at a glance, but a light blur can sometimes be partially reversed. If you're hiding something sensitive for real, use a strong radius — or better, fully cover it with the Pixelate tool or a solid block. For genuinely irreversible redaction, paint over the area completely.
FAQ
How do I blur an image online?
Drop it above, set the blur radius, and click Blur — the softened image appears with a Download link. All processing is in your browser; nothing uploads.
Does it blur the whole image or just part?
The whole image. To blur or hide only a region, use Pixelate, which lets you select an area.
Is transparency preserved?
Yes — the output is a PNG and any transparent areas stay transparent (their edges soften along with everything else).
