This project is written around the ffmpeg.wasm library (https://github.com/ffmpegwasm/ffmpeg.wasm) which allows to use ffmpeg within browsers. This project is meant to be a static Web-App, so no data except the default github.io statistics are being send to servers. Video, audio and image editing happens completely on the browser side.
The project was developed with Svelte with JavaScript.
The static Web-App is available under https://schmiederdaniel.github.io/FFmpegWebUI/
