What is WAV?
WAV stores audio as uncompressed PCM, exactly as it was recorded. That makes it the standard for recording, editing and mastering, where no quality can be lost, but a WAV file is about ten times larger than the same audio in MP3.
What is WebM?
WebM is an open, royalty-free video format backed by Google and designed for the web. It uses VP8, VP9 or AV1 video with Opus or Vorbis audio, plays natively in modern browsers and keeps files small, though some editors and Apple devices handle it poorly.
Tips for converting WAV to WebM
- Converting a compressed file such as MP3 to a lossless format does not restore detail already removed; it only makes the file larger.
- For music, a lossless source (WAV or FLAC) gives the best result when you convert to WebM.
- Check that your player, car stereo or editing app supports WebM before converting a whole library.
- Keep the original WAV file as a backup until you are happy with the converted audio.
