What is javascript-image-background-remover?

This project is a free web tool for removing the background from an image so you get a transparent PNG file, and it does all the processing right inside your browser. Your photos are never uploaded to a server, since the AI model that detects the background runs locally on your own device using a technology called ONNX Runtime Web. Because nothing leaves your device, the project advertises strong privacy: there are no logs, no server storage of your files, and no login is required to use it. If the automatic background removal misses a detail around the edges of a subject, a built in mask editor lets you zoom in with high precision and manually clean up the result, with an undo function available if you make a mistake. Once you are happy with the result, you can download it as a PNG file with proper transparency. The tool is described as completely free with no watermarks on the output, no hidden paid tiers, and no advertisements. There is a hosted online demo linked in the README if someone wants to try the tool before downloading the code themselves. On the technical side, the project is built with plain JavaScript, HTML, and CSS, without relying on a heavy backend framework. It uses WebAssembly and WebGL through ONNX Runtime Web to run the AI model efficiently in the browser, and it uses the Canvas API to handle pixel level editing for the mask tool. The project welcomes outside contributions through the usual fork, branch, and pull request process, and it is released under the MIT license.
