About this tool

This tool applies a Gaussian blur to your image using the HTML5 Canvas API with CSS filter: blur(). Everything runs in the browser — your image is never sent to any server. It supports JPEG, PNG, WebP, and GIF files. Common uses include blurring backgrounds, censoring sensitive information, creating depth-of-field effects, or softening textures.
