Background music, lectures and interviews often only need the soundtrack. Convert MP4 to MP3, MOV to MP3, or extract audio from WebM, MKV and AVI as MP3, M4A or WAV—no account, no watermark on export.
MP3 works almost everywhere; M4A balances size and quality; WAV keeps uncompressed PCM for further editing. Convert the video format first if needed, or compress a huge file before extracting.
MP4 to MP3, MOV to MP3, and audio from WebM, MKV or AVI—export MP3, M4A or WAV for playback, editing or lossless backup.
No desktop software and no paywall to remove a logo. Download as soon as extraction finishes.
Choose MP3, M4A or WAV for listening, editing or lossless backup—from common MP4, MOV, WebM and more.
Drop the video here, choose MP3, then start extraction. Preview the audio and download when it sounds right.
Choose MP3 for everyday playback and sharing, M4A for a solid quality/size balance, and WAV when you need lossless audio for further editing (larger files).
No watermark. We export the video’s existing audio track. Silent videos or damaged tracks cannot produce usable audio.
Make sure the source video actually has an audio track and plays with sound. Silent, damaged or unusual files may fail—try converting to MP4 first or use another clip.
Common MP4, MOV, WebM, MKV and AVI files work. Keep files under about 500MB; trim very long clips if your device runs out of memory.
The tool only separates the track. Music and voice rights depend on your own licenses—confirm before publishing.
Yes on phones. If it fails, try a computer, confirm the video has sound, or convert to MP4 first.
