About WebM
WebM is an open, royalty-free video format developed by Google and based on the Matroska container. It holds VP8, VP9 or AV1 video with Vorbis or Opus audio.
It is made for the web: all major browsers play it in the HTML video element, and it is common for screen recordings and short clips.
WebM allows only its own small set of codecs, so H.264 video or AAC audio has to be re-encoded to fit.
Convert WebM to FLAC online free, no account required — FLAC is a lossless compressed audio format.
Change WebM to FLAC without losing quality — convert WebM to FLAC free in your browser.
Why can't I upload my WebM video to Instagram or TikTok? Social apps almost always demand MP4, so a WebM made for the web needs converting before it will upload.
About FLAC
FLAC (Free Lossless Audio Codec) compresses audio without losing anything: the files are typically half to two thirds the size of WAV and decode back to the exact original samples.
Music archives, CD rips and high-resolution downloads.
FLAC files are several times larger than MP3, and some older players and car stereos do not play them.
Why convert CDs to FLAC instead of MP3? The copy is bit-for-bit identical to the original, so the archive never loses quality however often it is converted later.
What changes when you convert WebM to FLAC
- The soundtrack of the WebM is re-encoded as FLAC at the default settings, so it is close to the original but not bit-identical.
- Only the sound is kept: the FLAC file contains the audio track of your WebM, and the picture is dropped.
Settings you can change
