Drop an MP4, MOV, WEBM or MKV and rip its audio track to MP3, WAV, AAC, M4A or OGG. A real FFmpeg engine runs entirely in your browser (with a live progress bar and an in-page audio preview) so your video never leaves your device.
Extract Audio from Video rips the sound track out of an MP4, MOV, WEBM, MKV, AVI or M4V file and saves it as MP3, WAV, AAC, M4A or OGG. Built on FFmpeg in the browser, it shows a live progress bar and lets you preview before download. Free and fully private.
Extract Audio from Video is a browser-native audio ripper built on FFmpeg compiled to WebAssembly. Point it at a video and it demuxes the audio stream and re-encodes it to the format you choose, MP3 for universal compatibility, WAV for lossless editing, AAC or M4A for Apple-friendly quality-per-byte, or OGG Vorbis for open-format smallness. Because the whole pipeline runs on your own machine, a lecture recording, an unreleased track, a client's interview or a private voice memo is never uploaded to a server. The FFmpeg core is fetched from this site the moment you press Extract and everything after that happens locally. Drop your file (MP4, MOV, WEBM, MKV, AVaudio-bearing formats and more), choose an output format, and watch a real progress bar as FFmpeg transcodes. When it finishes you get an inline player to check the result before you download, plus the exact output size. The tool is honest about its limits: WebAssembly transcoding is slower than a native desktop app and holds the file in memory, so it shines on typical clips and gets sluggish on multi-gigabyte movies, for those, trim first or expect a wait. No account, no watermark, no upload, no size games: just your video in, an audio file out, on your device.

Drag an MP4, MOV, WEBM or MKV onto the workspace, or click to browse. The tool probes it locally and shows the name, size and duration. Nothing is uploaded.
Choose MP3, WAV, AAC, M4A or OGG. If you're not sure, MP3 plays everywhere. Pick WAV when you'll edit the audio afterward and want it lossless.
Press Extract Audio. On the first run the FFmpeg engine loads once (a brief wait), then a live progress bar tracks the transcode as it works on your device.
Play the result in the built-in audio player to confirm it sounds right, check the output size, then download the file. Start over anytime to rip a different clip.
Save the extracted track as MP3 (universal), WAV (lossless, edit-ready), AAC or M4A (great quality-per-byte for Apple), or OGG Vorbis (small, open): pick per job, not per tool.
Uses the same FFmpeg engine desktop apps rely on, compiled to WebAssembly and run client-side. No install, no command line, no upload: the core loads only when you press Extract.
When extraction finishes, an inline audio player lets you confirm the track sounds right (start, end and quality) before you download a single byte.
A real progress bar reflects FFmpeg's actual work, with a one-time note while the engine loads on first run, so you always know it's moving and never wonder if the tab froze.
MP3 rips at a high-quality VBR setting, AAC/M4A at 192 kbps, WAV as 16-bit PCM and OGG at a balanced quality target, good defaults so the output sounds like the source, not a compressed copy.
Your video is processed entirely on your device and never uploaded. Rip audio from confidential interviews, unreleased music or personal recordings, close the tab and every trace is gone.
Skip the desktop install and the sketchy 'converter' sites. Drop a video, pick a format, download the audio. The whole loop is a few clicks and it happens on your machine.
Because nothing is uploaded, you can pull audio from a client interview, a medical recording or an unreleased mix without it ever touching a third-party server.
Choose WAV when you're editing in a DAW, MP3 when you just need something that plays everywhere, or AAC/M4A for Apple devices. No lossy round-trips you didn't ask for.
There's no sign-up, no length cap traded for an email, and no audio watermark stamped on the result. The tool is free because it runs on your hardware, not ours.
From quick one-off fixes to daily workflows, see how people put this tool to use.
Recorded on Zoom or a camera and only need the sound? Extract the audio to MP3 or WAV and drop it straight into your editing timeline. No re-recording, no upload.
Rip audio from a live-performance or rehearsal video to WAV so you can study, sample-check or master it in your DAW without transcoding losses.
Extract a recorded class or talk to MP3 so it plays on any phone offline for the commute, smaller than the video and private, since the file never leaves your laptop.
Grab the audio track from a rough cut to clean, mix or transcribe it elsewhere, then bring it back, a quick demux without opening the whole project.
Accepts MP4, MOV, WEBM, MKV and AVI, and produces MP3, WAV, AAC, M4A and OGG, all processed locally in your browser.

Transcribe video and audio in your browser, then edit, search, label speakers and export. Speech recognition runs on your device. Nothing is uploaded.
Turn a video into a high-quality animated GIF right in your browser. Pick a start, duration, frame rate and width, get a two-pass palette for clean color, then preview and download. Nothing is uploaded.
Trim audio in your browser with a real waveform: drop an MP3, WAV, M4A or OGG, drag a selection to keep exactly the part you want, preview it, then download a lossless WAV or a compact MP3. Sample-accurate and 100% private. Nothing is uploaded.
Convert any audio to MP3 in your browser, WAV, M4A, AAC, OGG, FLAC and more to a clean, universally-playable MP3 with a bitrate you choose. Preview the waveform, encode locally with lamejs, then download. Nothing is uploaded.
Normalize audio volume in your browser: lift a too-quiet recording to a clean target level with peak or RMS normalisation, compare the before/after waveform, then download WAV or MP3. Nothing is uploaded.
Turn client Looms, screen recordings and voice notes into developer-ready tasks, bugs, design changes, screenshots and acceptance criteria: each traceable to the moment it was asked for.
Go deeper on the concepts behind the extract audio from video.
Hit a snag? Here are quick fixes for the issues people run into most.
WebAssembly transcoding is CPU- and memory-bound. Try a smaller or trimmed file, close other heavy tabs, and use a desktop browser rather than a phone. The progress bar confirms it's still working even when it's slow.
The source likely has no audio stream (common with silent screen recordings). Confirm the original video actually plays sound in a media player. If it doesn't, there's nothing to extract.
The file is probably too large for in-browser processing. Trim it to just the part you need first, or extract on a machine with more RAM. Very large MKV/MOV files are the usual culprit.
That's the one-time FFmpeg WebAssembly core download (~30 MB), it's expected and only happens once per session. After it loads, further extractions start immediately.
Pick WAV if the audio is headed into a DAW or editor: it's lossless. Use MP3 when you just need something that plays anywhere and stays small.
For a multi-gigabyte movie, trim the section you need first (in the Trim tool) so the extractor has far less to chew through.
Close other memory-heavy tabs before extracting a large file: WebAssembly holds the video in memory and a crowded tab set can push it over the edge.
Use the built-in player to spot-check the start and end of the track before downloading, especially for long recordings.
AAC or M4A gives noticeably better quality than MP3 at the same size if your target devices are Apple.
Recent updates and improvements to the extract audio from video.
Initial release, in-browser audio extraction to MP3, WAV, AAC, M4A and OGG via FFmpeg WebAssembly, with drag-and-drop, a live progress bar, an inline audio preview and one-click download.
Added an inline player to audition the result before download, honest engine-loading and size warnings for large files, and higher-quality default encode settings per format.
Improved the no-audio-track message, refined progress reporting on long clips, and tightened memory handling so bigger videos are less likely to fail mid-extract.
Your video is read and processed entirely in your browser using FFmpeg compiled to WebAssembly. It is never uploaded to any server. The only network request is fetching the FFmpeg engine from this site on first use. Your file's data stays on your device. Nothing is stored, logged or transmitted, so you can safely rip audio from confidential interviews, unreleased music and personal recordings. Close the tab and every trace is gone.
