Blur Image

Drop in an image and download a blurred version. The radius controls how soft the result is — 1 is barely blurred, 5 (default) is a gentle smoothing, and 20 is a strong glassy effect. Implementation is a two-pass separable box blur with a running window sum, so even multi-megapixel images stay responsive. For visually-Gaussian results, chain multiple smaller blurs (or just raise the radius). Output format matches the input where possible, defaulting to PNG. Everything runs locally in your browser.
