Convert WebM to WAV online for free and extract audio from video. Use this converter for music tracks, lectures, interviews, podcast source files, and listening without the video stream.
Converting WEBM to WAV extracts the audio track from the video and discards the visual frames. The result is typically 80–95% smaller than the source WEBM file and is suited for music players, podcast apps, or further audio editing.

WAV is uncompressed lossless audio — pristine but large (~10 MB per minute at CD quality). Convert to WAV when your destination is audio production (DAWs like Logic, Ableton, Pro Tools all use WAV natively), voice-over delivery, or when a broadcaster / stock-audio marketplace specifies uncompressed. Never for casual listening — file sizes make no sense.
Pulling the soundtrack out of a video means dropping every video frame and keeping only the audio stream — smaller file, listen-only content.
Files up to 10 MB on the free plan, up to 1 GB on Pro — enough for lecture recordings, music videos, podcast video versions, and screen captures. Long videos (hour-plus) need Pro because the audio track alone can push past the free ceiling.
For voice content (interviews, lectures, podcasts), 128 kbps WAV is more than enough. For music, aim higher — 192 kbps for casual listening, 320 kbps if you want transparency to the source. The source can't go higher than it already is; if the video's audio was already 128 kbps AAC, exporting at 320 kbps just makes a bigger file.
Extraction is fast — a 30-minute video typically produces its WAV in a few seconds. Both the video you uploaded and the extracted audio are permanently deleted from our servers within 30 minutes.
A WEBM container holds separate video and audio streams. Extraction reads the audio stream, re-encodes it (or copies it, if the target codec matches) into your chosen WAV container, and throws away the video entirely. Metadata like title and track info carry over where the format supports it.
Six scenarios where extracting audio to WAV solves a real problem.
A recorded lecture, webinar, or class captured as WEBM carries hours of good audio and a static talking head. Extracting to WAV produces something you can listen to on a commute — much smaller, playable on any audio app.
For music videos of tracks you own, extracting the WAV lets you add the song to your regular listening rotation without needing to keep the video around. (Do keep an eye on rights — extraction from third-party sources isn't a licence.)
Recording a video interview and then distributing the audio-only version to podcast platforms is standard practice. Extracting to WAV gives you the podcast episode without touching the video edit.
Whisper, Otter, and every other transcription service accept audio directly. Uploading video wastes bandwidth and, in some cases, is rejected outright. Extract to WAV first, upload, get the transcript back in a fraction of the time.
Sound effects and short clips extracted from videos become WAV files ready to import into audio editors, DAWs, or ringtone makers. Video is unnecessary baggage for these use cases; extracting saves the round-trip.
A 1 GB WEBM lecture recording carries maybe 60 MB of actual audio. If the video track is disposable — say, a talking head — extracting to WAV cuts storage by 90% while preserving the content that matters.
Technical comparison of the two formats — useful for deciding which to use, or for confirming what changes during conversion.

WebM is an open-source multimedia container format launched by Google in 2010 as a royalty-free alternative to proprietary video formats. Built on the Matroska container, WebM pairs VP8, VP9, or AV1 video codecs with Vorbis or Opus audio codecs. It was designed from the ground up for efficient HTML5 web video delivery, offering smaller file sizes and faster loading times than many traditional video formats while maintaining high visual quality.
WebM is optimized for web streaming and is supported natively by all major modern browsers including Chrome, Firefox, Edge, and Opera. Its open-source, royalty-free licensing makes it particularly attractive for platforms that need to serve video at scale without codec licensing fees. The main limitation is that WebM has less support on native device players and older hardware compared to MP4, making it best suited for web-first video distribution rather than offline or cross-device playback.
