# Third-party software included in this site

This site bundles the following third-party, open-source components inside the `vendor/` folder so the audio converter can run entirely in the visitor's browser.

## @ffmpeg/core (the FFmpeg WebAssembly engine)
- Location: `vendor/core/`
- License: **GPL-2.0-or-later**
- Full license text: `vendor/core/GPL-2.0-LICENSE.txt` (included in this folder)
- Source code: https://github.com/ffmpegwasm/ffmpeg.wasm-core
- This is an unmodified WebAssembly build of FFmpeg (https://ffmpeg.org), compiled by the ffmpeg.wasm project. It was built with GPL-licensed components enabled, which is why the compiled binary is GPL-2.0-or-later rather than the more permissive LGPL that FFmpeg uses by default.
