Extract lossless audio from a video
When you need the cleanest possible audio — for editing in a DAW, feeding a transcription tool, or archiving a master — an uncompressed WAV is the right format. Unlike MP3, WAV throws nothing away, so there are no compression artefacts to work around.
Mynify extracts the audio entirely in your browser — the video is decoded and written to WAV on your device, with nothing uploaded.
WAV vs MP3
- WAV — uncompressed, largest files, best for editing and transcription.
- MP3 — compressed, small, perfect for listening and sharing. Use MP4 to MP3 for that.
Because WAV is uncompressed, expect the output to be substantially larger than the video’s audio would be as an MP3 — that’s the cost of keeping every detail.
How it works
- Drop your video.
- Mynify loads its engine once (~30MB, cached), then extracts the audio.
- Download the WAV.
Free, unlimited, no signup, no watermark — your video never leaves your device.
