About the Blur Image
Add a Gaussian blur to a whole image or soften it for backgrounds, with an adjustable radius and live preview. No uploads.
Blur Image is part of a free, privacy-first toolkit. Everything is processed locally on a Canvas with high-quality pica resampling — there are no uploads, no quality loss from a server round-trip, and no limits.
Because blur image works without any sign-up or installation, you can use it as often as you like and it's always available — on desktop or mobile, and even offline.
