Need just the sound from a video? This free tool lets you extract audio from a video and save it as an MP3 or WAV in seconds — great for grabbing a song, a voiceover, a podcast recording or an interview from an MP4. Optionally trim it to the exact part you want. Everything runs in your browser, so your video never leaves your device.
No signup, no watermark, no software to install — just drop in a video and download the audio.
Extract Audio from Video
Pull the audio out of a video and save it as an MP3 or WAV — free, in seconds. Drop in an MP4, MOV or WebM, optionally trim to just the part you want, and download. Everything runs in your browser, so your video never leaves your device.
How it works: the audio track is decoded and re-encoded entirely in your browser — nothing is uploaded, and there’s no watermark. Works with common formats (MP4, MOV, WebM, M4A); some containers like MKV/AVI aren’t supported by browsers — convert to MP4 first. Got the audio? Clean it with the AI Audio Enhancer, transcribe it, or remove the vocals.
How to extract audio from a video
- Upload your video (MP4, MOV, WebM or M4A). It’s processed locally — nothing is uploaded.
- Trim if you want — drag the start and end handles to keep just a section, or leave it to export the whole audio.
- Pick a format. MP3 (choose a bitrate) for a small, shareable file, or WAV for lossless quality.
- Download your audio.
MP3 or WAV — which should you choose?
MP3 is compressed and small, perfect for sharing, uploading or listening — 320 kbps is near-transparent, 128 kbps keeps the file tiny. WAV is lossless and larger, best if you’ll edit the audio further (transcribe, clean, remix) and want maximum quality to work from.
What you can do with the extracted audio
- Transcribe it — turn a video’s speech into text or subtitles with the AI Transcription tool.
- Clean it up — remove background noise and echo with the AI Audio Enhancer.
- Remove the vocals — pull an instrumental from a music video with the AI Vocal Remover.
- Make a ringtone — cut a hook into a phone-ready clip with the Ringtone Maker.
Supported formats
This tool reads the audio track directly in your browser, so it works with the formats browsers can decode: MP4, MOV, WebM and M4A. Some containers like MKV and AVI aren’t supported by browsers — convert them to MP4 first, then extract the audio here.
Free and completely private
The audio is decoded and re-encoded entirely on your device, so your video is never uploaded and there’s no watermark or file-size paywall. It’s free to use as much as you like.
Frequently asked questions
How do I extract audio from a video for free?
Upload the video here, optionally trim it, choose MP3 or WAV, and download. It runs in your browser with no signup, no watermark and nothing uploaded.
What video formats are supported?
MP4, MOV, WebM and M4A — the formats browsers can decode. Convert MKV or AVI files to MP4 first.
Can I convert MP4 to MP3?
Yes — upload the MP4, choose MP3 and a bitrate, and download. You can also export lossless WAV.
Does it upload my video?
No. Everything is processed locally in your browser, so your video and audio never leave your device.
Can I extract just part of the video’s audio?
Yes — use the trim handles to set a start and end point, and only that section is exported.
Is there a file size limit or watermark?
No watermark, and it handles large videos (up to about 250 MB) right in the browser. Very long videos use more memory, so trimming first helps.
