Can I extract audio from several videos at once?

Yes. Drop multiple files and each one is extracted separately using the same format, bitrate and trim settings. Every result gets its own player and download button, and Download all saves them together.

How does trimming work?

Enter a start and end time in seconds. Every file is clipped to that range before extracting; leave the end blank to keep the audio to the very end.

What do the bitrate, normalize and mono options do?

Bitrate sets the quality of MP3 and M4A output. Normalize loudness evens out the volume using EBU R128 loudness targets, and mono downmix merges stereo channels into one. Normalizing or downmixing re-encodes the audio, so Original copy mode is skipped when either is on.

Is there a file size limit?

Everything runs in your browser's memory, so very large videos can run out of memory. Files over about 500MB show a warning and files over 2GB are blocked. For big clips, a desktop tool may work better.

Are my videos uploaded anywhere?

No. Extraction runs 100% client-side with ffmpeg compiled to WebAssembly. Your videos stay on your device and are never uploaded, sent, or stored on any server.

Extract audio from one or many videos to MP3, M4A, or WAV, trim clips, normalize loudness, or downmix to mono — all privately in your browser.

Loading tool…

Video to Audio Extractor — Pull the soundtrack out of one video or a whole batch and download each as an audio file. Drop in MP4, MOV, WebM, MKV or almost any video, extract to MP3, M4A, or WAV (or copy the original track without re-encoding), and fine-tune the result: clip it to a start and end time, pick an output bitrate, normalize the loudness, or downmix to mono. Everything runs locally with ffmpeg compiled to WebAssembly, so your videos are never uploaded to a server.

What is Video to Audio Extractor?

A free online video-to-audio extractor that rips the audio track out of your videos and saves them as standalone audio files, right in your browser. It processes a single clip or a whole batch of videos at once, so podcasters, editors, students and musicians can grab songs, voice-overs, interviews or lectures without installing desktop software. It reads common containers like MP4, MOV, WebM, MKV and AVI, and lets you re-encode to MP3, M4A (AAC) or WAV, copy the original stream untouched, trim to a start–end time, choose the output bitrate, normalize loudness, and downmix stereo to mono. Because it is powered by ffmpeg compiled to WebAssembly, the whole process happens on your device and your videos never leave your computer.

How to use Video to Audio Extractor

Drop one or more video files onto the dropzone, or click to pick them. The first run downloads the in-browser conversion engine once.
Wait a moment while each clip is read and its duration and source audio (codec, sample rate, channels) are detected.
Choose an output format: MP3, M4A (AAC), WAV, or Original to copy the source audio without re-encoding.
Optionally set a start and end time to trim every clip, and open Options to pick a bitrate, normalize loudness, or downmix to mono.
Let each file extract automatically, preview any result in its player, then download a single file or use Download all.

Examples

Batch-extract MP3s from several clips

Drop a stack of MP4s at once, keep the format on MP3, and each clip is extracted to its own .mp3. Use Download all to save the whole batch in one go.

Trim and normalize a lecture

Set a start and end time to cut the intro, turn on Normalize loudness so a quiet recording plays back at a consistent level, and export a tidy M4A.

Copy original audio, or downmix to mono

Pick Original to stream-copy the source track with no quality loss and the fastest processing, or enable mono downmix to shrink a voice recording.
