Image to Blur

Yes. 100% free, no signup, no watermark, no daily limit. Blur as many images as you want.

Four: Gaussian (the native Canvas filter — smooth, fast, the classic photo blur), Box (a manual separable box-blur that averages a 2*radius+1 neighborhood in two passes — a clean uniform blur), Motion (a horizontal-only blur that averages pixels along a left-right line, producing a speed streak), and Radial (a zoom/explode effect that samples along the line from image center through each pixel at increasing zoom factors).

For every output pixel, the tool samples `radius` points along the line from the image center through that pixel, at zoom factors interpolated from 1.0 (the pixel itself) up to 1.0 + radius/50. Averaging those samples produces the zoom/explode trail effect. Higher radius = stronger zoom.

No. All processing happens in your browser using the HTML5 Canvas API. Your image is never uploaded to any server.

To keep the tool fast and crash-free on phones and tablets. Images larger than 4096px on the longest side are scaled down proportionally before blur processing — the blur result is fully preserved. Canvas processing is wrapped in try/catch so any error is silently ignored.
