What is background-remover?

This repository is a single-file browser-based image editor focused on background removal, written entirely in Thai in the README. The application runs directly in any modern web browser from a single HTML file, with no installation, no server upload, and no backend required. All processing happens locally on your own device. The tool offers three methods to remove an image background. The first uses an AI model that detects and removes backgrounds automatically with one click, best suited for photos of people, animals, or products with a clear subject. The first time you use the AI method it downloads a model file of about 40 megabytes, which is then cached in your browser so subsequent uses work offline. The second method is a magic wand selector that removes areas of similar color when you click on them, useful for images with a solid or uniform background like white or blue. The third method is a manual brush that lets you paint over areas to erase or restore them at your chosen brush size. Beyond background removal, the editor includes tools to crop the image by drawing a selection area, rotate and flip in 90-degree increments or by a custom angle, resize the image to specific pixel dimensions while optionally locking the aspect ratio, and resize the canvas independently from the image to add or trim blank space around it. The canvas resize tool includes an anchor control to decide which direction the extra space is added. Images can be loaded by clicking a button, drag and drop, or pasting from the clipboard with Ctrl+V. Finished images can be saved as PNG, JPG, WebP, GIF, or BMP, or copied directly to the clipboard. JPG and WebP exports include a quality slider. The editor keeps up to 20 steps of undo and redo history. The README notes that the application was built with Claude Fable 5 on June 11, 2026. No license is stated in the README.
