Blur Image details
First, Blur Image reads PNG, JPG, JPEG, WEBP, GIF, BMP, and AVIF source files and prepares PNG output for the image workflow. Next, The visible controls are Blur radius. Additionally, Files and text stay in the browser session.
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. Blur Image runs locally in your browser.
