Pull the audio out of any video — MP4, MKV, MOV or WEBM — and save it as MP3 or WAV. Free, private and entirely in your browser; your video is never uploaded.
Open the Audio Studio
Go to the DefyAudio Studio — it extracts audio from video right in your browser.
Add your video
Drag and drop or browse for an MP4, MKV, MOV or WEBM file. DefyAudio reads the video and pulls out its audio track automatically.
Choose the output format
Pick MP3 for a small, universally playable file, or WAV to keep full uncompressed quality for editing.
Extract and download
Click Convert. The audio is extracted locally and downloads instantly — the video never leaves your device.
Any common video
MP4, MKV, MOV and WEBM — the audio track is extracted from all of them.
MP3 or WAV out
Compact MP3 for playback, or lossless WAV for further editing.
Edit after extracting
Trim, split into tracks, join or clean up the extracted audio in the same Studio.
A video-to-audio extractor takes the soundtrack out of a video file and saves it as an audio file you can play, edit or share. It's the fastest way to keep the audio from an interview, a lecture, a music video, a screen recording or a phone clip without the picture.
DefyAudio reads the video and decodes its audio entirely in your browser via WebAssembly — nothing is uploaded, so even private recordings stay on your device. Once extracted, the audio drops straight into the Studio, where you can trim it, split it into tracks or clean it up.
Open DefyAudio's Studio, drop in your MP4, MKV, MOV or WEBM video, choose MP3 or WAV as the output, and click Convert. The audio downloads instantly — free, with no upload.
