Image Blur Tool
Apply a downloadable box blur to local raster pixels.
How Image Blur Tool works
Image Blur Tool is designed to apply a downloadable box blur to local raster pixels. For every pixel and channel, the box blur averages all neighbors inside the selected square radius with edge coordinates clamped. Image Blur Tool adds a focused result for this operation. For Image Blur Tool, because the page shows the computed result directly, the current settings can be evaluated without treating the preview as a black box.
A radius of 1 replaces each channel with the average of its surrounding 3 by 3 neighborhood. Use it to soften a texture, obscure small details, or prepare a low-frequency background from a local image. In Image Blur Tool, use the default as a baseline, then compare another setting against it before applying the output elsewhere.
Limits, output, and privacy
Runtime grows with radius and image area because each output pixel visits the full neighborhood rather than using a separable approximation. For Image Blur Tool, large source images require more memory because the browser holds both source and output pixel buffers while processing. Image Blur Tool keeps the operation client-side. With Image Blur Tool, nothing entered here is sent to a remote service; copying or downloading operates on the browser-held result.
