Blur Background (blurbackground.vip) is a free, browser-based tool that blurs the background of a single photo using local, in-browser AI processing, without requiring an account or uploading the image to a server. Users pick a JPEG, PNG, WebP, or several other supported formats, let the tool separate the subject from the background, adjust blur strength, compare before and after, and download the result.
An "Advanced Bokeh" option is available alongside the free basic local-processing path for more refined depth-of-field-style results, aimed at quick portrait, product, and social-media photo edits rather than batch or professional retouching workflows.
