Video to MP3 Converter
Free online video to MP3 converter. Drop an MP4, MOV, WebM, MKV or AVI, choose a bitrate and download just the audio as an MP3 — no upload, no software to install.
Turn any video into an MP3
A video to MP3 converter pulls the soundtrack out of a video file and saves it as a plain MP3 you can play anywhere — no picture, just the audio. It's how you keep the music from a concert clip, grab a lecture or podcast recording to listen to on the move, save a voice memo you filmed, or lift a backing track from a rehearsal video. Drop your file above — MP4, MOV, WebM, MKV, AVI and most other formats all work — pick an MP3 bitrate and press Extract MP3. Everything runs on your device with ffmpeg compiled to WebAssembly, so the video never leaves your computer, unlike the many "online" converters that upload your file to a server first. Extracting audio is far lighter than re-encoding the video, so even long recordings usually finish quickly. Want to keep the video but make it a different format? Use the Video Tools. Need to cut the audio down afterwards? Send the MP3 to the MP3 Trimmer.
How to convert a video to MP3 in three steps
All three happen in your browser — nothing is uploaded.
- Load your video. Drag a file onto the box above, or click it to choose one. MP4, MOV, WebM, MKV, AVI and most phone and screen-recording formats all work.
- Pick a bitrate and extract. Choose an MP3 bitrate between 96 and 320 kbps — higher for music, lower for speech — then press Extract MP3. The first run in a session downloads the ffmpeg engine (about 10 MB); after that it starts instantly.
- Preview and download. Play the result in the page, then download the .mp3. No watermark, no sign-up.
Which bitrate for which video?
| Source | Suggested MP3 bitrate | Why |
|---|---|---|
| Music video / concert clip | 256–320 kbps | Keeps instruments and cymbals clean |
| Podcast / interview | 128–192 kbps | Clear speech at a small file size |
| Lecture / meeting recording | 96–128 kbps | Voice only — smallest sensible file |
| Voice memo you filmed | 128 kbps | Plenty for a single speaker |
The audio inside a video is already compressed once, so choosing a bitrate far above the original won't recover detail — it just makes a bigger file. When in doubt, 192 kbps is a safe all-round choice.
Frequently Asked Questions
How do I convert a video to MP3?
Drop your video onto the box above (or click to choose it), pick an MP3 bitrate, and press Extract MP3. The tool discards the picture, re-encodes the soundtrack to MP3 on your device and shows a download button — no upload, no sign-up. The engine downloads once (about 10 MB) on the first conversion, and later runs start instantly.
Which video formats can I extract audio from?
MP4, MOV, WebM, MKV, AVI, M4V and most other common containers work, because the tool uses ffmpeg — the same engine desktop converters are built on. It reads the audio track from the file and encodes it to MP3, whatever the video codec inside. The file picker accepts any video file your browser will hand it.
Is this video to MP3 converter free and private?
Yes — this video to MP3 converter is free, with no sign-up and no watermark. The extraction runs entirely in your browser with ffmpeg compiled to WebAssembly — your video is never uploaded, logged or stored. That makes it safe for private recordings, lectures and music you own, and closing the tab clears everything.
What MP3 bitrate should I choose?
For music from a video, 256 or 320 kbps keeps it clean. For a lecture, podcast or voice recording, 128 kbps is plenty and produces a much smaller file. The audio inside a video is already compressed, so going far above its original quality does not add detail.
How big a video can I convert?
A video has no server-side size cap, because the extraction happens in your browser tab — the ceiling is your device's memory. Extracting audio is much lighter than converting the video itself, so long files are usually fine, but a multi-gigabyte 4K recording can run out of memory. If a very long file stalls, trim it first with the Video Trimmer. You need a current Chrome, Edge, Safari or Firefox — the engine uses WebAssembly and DecompressionStream.
