Sometimes you only need the audio from a video: a lecture recording you want to listen to on a commute, a music video whose soundtrack you want to keep, or a screen recording whose narration you need as a standalone clip. Re-encoding the whole video just to get the audio track is wasteful, and most video editors make this a surprisingly multi-step process.

This tool extracts the audio track from any uploaded video file — MP4, MOV, AVI, MKV, and more — and delivers it as a clean audio file ready to use. No video editing knowledge required, no desktop software to install. Upload the video, and the audio comes right back out.

How Audio Extraction Works

Audio extraction uses FFmpeg's stream demuxing capability running in WebAssembly inside your browser. Rather than decoding and re-encoding the video, the tool identifies the audio stream in the container and remuxes it into a standalone audio container. When the source audio codec matches the target format, this is a lossless, near-instant operation — no quality is lost because no re-encoding occurs.

When the source codec differs from the chosen output format, the audio is decoded to raw PCM and re-encoded using the appropriate codec. The video stream is discarded entirely and never processed, which keeps memory usage low and extraction fast regardless of video resolution or length.

Frequently Asked Questions

Which video formats are supported?

MP4, MOV, WebM, AVI, MKV, FLV, WMV, and OGV. Files up to 100 MB are accepted.

Which bitrate should I choose?

128 kbps is fine for speech and podcasts. 192 kbps suits music. 320 kbps is for audiophiles — the file will be larger.

What if my video has no audio?

If the video contains no audio track, the extraction will fail with an error message. Use a video that has an audio stream.

Dedicated Extractor vs General Video Editor

General-purpose video editors like Premiere or DaVinci Resolve can export audio tracks, but the workflow involves importing the video, navigating export settings, and waiting for a full render pipeline to initialise. This tool skips all of that — it does one thing and does it instantly in your browser, making it the right choice whenever extraction is the only goal.

FileCrank Video to Audio extracts audio from MP4, MOV, WebM, AVI, MKV, and other video files. Output to MP3, WAV, FLAC, OGG, or AAC. Free, no signup, files deleted within 1 hour.
