Video to MP3
Extract audio from any video file as MP3, WAV, or M4A.
About Video to MP3
Sometimes you only need the sound: a lecture recording to listen to on your commute, an interview to feed into transcription software, or the audio track from your own footage. This free tool extracts audio from video online — convert video to MP3, WAV, or M4A from any common format including MP4, MOV, AVI, WebM, and MKV, with files up to 500 MB supported. There is no sign-up and no watermark: drop a file, pick a format, and download the audio in seconds.
Extraction is handled by ffmpeg on the server, the same engine professional studios rely on, so the audio track is pulled from your video cleanly and re-encoded exactly how you ask. Choose MP3 with a bitrate from 128 to 320 kbps for maximum compatibility, WAV for lossless audio you plan to edit in a DAW, or M4A for efficient AAC compression that sounds great at small sizes. When the extraction finishes you can compare the original and output file sizes before downloading.
How to extract MP3 audio from a video
- 1Drag and drop your video into the upload zone, or click it to browse — any common format up to 500 MB works.
- 2Choose an Output Format: MP3 (the default) for universal playback, WAV for lossless editing, or M4A for compact AAC audio.
- 3If you picked MP3, select a Bitrate from 128 to 320 kbps — 192 kbps is the default and a good balance of quality and size.
- 4Click Extract Audio and wait while ffmpeg strips the video track and encodes the audio.
- 5Review the result — format, duration, and original versus output size — then click Download to save the file.
Frequently asked questions
Which output format should I choose?
MP3 plays everywhere and is the safe default for podcasts, lectures, and general listening. WAV is uncompressed and lossless, making it the right choice if you plan to edit the audio afterwards. M4A uses AAC compression, which delivers better quality than MP3 at the same bitrate and suits Apple devices especially well.
What bitrate should I pick for MP3?
192 kbps is transparent enough for speech and casual listening — it’s the default for a reason. Choose 256 or 320 kbps for music, where the extra detail is audible, or 128 kbps when the smallest possible file matters more than fidelity.
Which video formats are supported?
Anything ffmpeg can read, which covers virtually every format: MP4, MOV, AVI, WebM, MKV, and footage straight from phones, cameras, and screen recorders.
Will extracting audio improve its quality?
No — extraction can never sound better than the audio embedded in your video. Picking a high bitrate simply avoids losing quality during re-encoding. If the source audio is 128 kbps, exporting at 320 kbps makes a bigger file, not a better-sounding one.
Are my videos stored on your servers?
No. Your upload is written to a short-lived temporary file so ffmpeg can process it, and both the video and the extracted audio are deleted from the server as soon as your download has been delivered. Nothing is kept, logged, or shared.
Is this video to MP3 converter free?
Yes — completely free, with no sign-up, no watermarks, and no daily limits beyond fair-use rate limiting.
