Why convert files in the browser?

Traditional online converters upload your file to a server, queue it, process it, and send it back. That is slow for large files, a privacy risk for personal photos and recordings, and the reason those sites need accounts and size limits. Amba's Tools runs the same open-source engines (libheif, FFmpeg, and our own Rust code) compiled to WebAssembly inside your browser tab. Your files never leave your device, there is nothing to sign up for, and there is no queue.

Everything works on desktop and mobile in current versions of Chrome, Edge, Firefox, and Safari. The first video conversion downloads the FFmpeg engine (about 30 MB) once; after that it is cached.
