Get just the audio from a video
Whether it’s a lecture you want as a podcast-style listen, music from a video, an interview to transcribe, or a voice memo captured on camera, extracting the audio as an MP3 is the quickest way to make it portable. MP3 plays on everything and takes a fraction of the space of the video.
Mynify does it entirely in your browser — the video is decoded and the audio encoded to MP3 on your device, so nothing is uploaded. That’s a real difference from typical “MP4 to MP3” sites, which send your whole video to their servers first.
How it works
- Drop your video (MP4, MOV, MKV, WebM…).
- Mynify loads its on-device engine once (~30MB, cached afterwards), then extracts the audio.
- Download the MP3 — 192 kbps, ready to play anywhere.
Good to know
- The first run is slower while the engine downloads; every conversion after that is fast.
- Longer videos take longer — it’s your device doing the work, not a server farm, which is exactly why it’s private.
- Need a different audio format? Try MP4 to WAV for uncompressed audio.
Free, unlimited, no signup, no watermark — and your video never leaves your device.
