Blur Image

Blur Image applies a smooth Gaussian blur across a photo. Use a light blur to create soft backdrops for text overlays, hero banners and presentation slides, or a heavy blur to anonymize faces, license plates, addresses and screenshots containing personal data before you share them.

The blur radius is adjustable from a barely-there 1 pixel up to a completely abstract 50 pixels, and the effect renders at full resolution on export rather than being scaled up from the preview — so there are no soft-edge artifacts in the downloaded file.

Nothing you open here is uploaded. The entire operation runs inside your browser tab using the Canvas API and WebAssembly, which means there is no upload queue, no server-side file-size cap, no watermark and no account. You can even go offline after the page has loaded and the tool will keep working. When you close the tab, every trace of your file disappears from memory — which is exactly what you want when you are handling ID documents, contracts, private photos or unreleased product shots.

Because the work happens on your own hardware, processing is effectively instant for typical photos and still comfortable for 50-megapixel files on a modern laptop or phone. There are no daily limits, no paywalls after five files, and no queue behind other users. Everything is free, unlimited and ad-supported, and the layout reserves fixed space for ads so the page never jumps while you work.
