The WASM core contains GPL codecs even though WeDoConvert exposes only
Audio tools: x264 and x265 are included upstream. Disabling Video pages does
not remove these components or their license obligations.

Linked libraries: x264 (GPL-2.0-or-later), x265 (GPL-2.0-or-later),
LAME (LGPL-2.0-or-later), libvpx (BSD), Ogg/Theora/Vorbis (BSD), Opus (BSD),
zlib (zlib), libwebp (BSD), FreeType (FTL/GPL), FriBidi (LGPL),
HarfBuzz (MIT-style), libass (ISC), zimg (WTFPL).
The accompanying original texts govern; these labels are a summary.
The application uses libmp3lame, PCM encoding, MP3/WAV decoding, and audio
decoding from MP4. Other linked codecs are not advertised as public tools.

There are no modifications to the distributed core binary. Rebuilding or
redistributing a changed core requires maintaining its corresponding source,
build instructions, notices and the applicable copyleft obligations.
