Kid3 needs Qt™. KDE is recommended but not necessary, as Kid3 can also be compiled as a Qt™ application. Kid3 can be compiled for systems where these libraries are available, e.g. for GNU/Linux®, Windows® and macOS®. To tag Ogg/Vorbis files, libogg, libvorbis and libvorbisfile are required, for FLAC files libFLAC++ and libFLAC. id3lib is used for MP3 files. These four formats are also supported by TagLib, which can also handle Opus, MPC, APE, MP2, Speex, TrueAudio, WavPack, WMA, WAV, AIFF files and tracker modules. To import from acoustic fingerprints, Chromaprint and libav are used.

Kid3 is available for most Linux® distributions, Windows® and macOS®. Links can be found on https://kid3.kde.org.
