What This Tool Does
This converter pulls the audio track out of a video file and saves it as MP3 or WAV — get the music from a concert clip, the dialogue from a lecture recording, or a podcast from a downloaded video. Drop the file, and the audio appears as an editable waveform in seconds.
Everything happens on your device: the browser's own decoder reads the video, and a small WebAssembly encoder writes the MP3. No upload, no queue, no account.

Not supported — convert to MP4 first
Support comes from your browser's built-in media engine, which is why it varies slightly. MP4 is the safe choice everywhere.
Cut Before You Convert
Most video-to-mp3 sites convert the entire track. Here the full audio editor opens first: drag the trim handles around the part you want, add a fade in or out, even adjust volume or EQ — then save. One pass, exactly the clip you need.
Tip:Need just a quote or a chorus? Trim it here before exporting instead of cutting the MP3 afterwards in another tool — you save a re-encode, and quality stays higher.
MP3 or WAV?
MP3 (high-quality VBR) is right for almost everything: small files, plays everywhere. Choose WAV when you plan to edit the audio further in a DAW — it's lossless, at the cost of much larger files.
Your Video Never Leaves Your Device
The decoder is the browser's own; the MP3 encoder is a small WebAssembly build that runs locally. Nothing is sent anywhere — close the tab and nothing remains.
Frequently asked questions
Is this video to MP3 converter free?
Yes. No sign-up, no watermark, no limits. Everything runs inside your browser, so there is nothing to pay for.
Does my video get uploaded?
No. The video is decoded locally by your browser, and the MP3 is encoded on your device too. The file never leaves your computer.
Which video formats are supported?
MP4, M4V, and MOV work in every major browser. WebM and OGV work in Chrome, Edge, and Firefox. MKV depends on the browser. AVI, WMV, and FLV are not supported — convert those to MP4 first.
What if my video has no sound?
A video without an audio track can't produce an MP3 — the tool shows a clear error instead of an empty file. Check that the video actually plays sound before converting.
Can I extract just part of the video's audio?
Yes — that's the big advantage here. The waveform editor opens first, so you can drag the handles around the section you want and export only that part.
What quality is the MP3?
High-quality variable bitrate (LAME VBR, roughly 190 kbps) — ideal for music and speech alike. Pick WAV instead if you need lossless audio.
Is there a size or length limit?
No hard limit, but the whole video is decoded in your browser's memory. Very large files (roughly over 500 MB) show a warning and may be slow on low-memory devices.
Does it work on my phone?
Yes — any modern mobile browser works. Keep in mind that big videos need a lot of memory, so short clips convert most reliably on phones.
