No software to install, no accounts to create — just drop the file and get your MP3.

How Video to MP3 Extraction Works
Video containers like MP4, MKV, and MOV store multiple streams together — video frames, one or more audio tracks, and optional subtitle data. Extraction demuxes (separates) the audio stream from the container without re-encoding the video, which means the process is fast and lossless up to the point of the final encode.
The audio stream is then transcoded to MP3 using LAME, the reference open-source MP3 encoder. A typical 128 kbps stereo encode preserves everything the human ear can detect from a standard video soundtrack. Higher bitrates (192 or 320 kbps) are available when source quality warrants it. The whole operation runs in your browser via WebAssembly-compiled FFmpeg, so your video never leaves your device.

Funktionen & Spezifikationen
Häufig gestellte Fragen
What video formats are supported?
MP4, MOV, WebM, AVI, MKV, FLV, WMV, and OGV. Files up to 50 MB are accepted.
Which bitrate should I choose?
128 kbps is fine for speech and podcasts. 192 kbps suits music and general audio. 320 kbps is for audiophiles or archiving — the file will be larger but indistinguishable from the original.
What if my video has no audio?
If the video file contains no audio track, the conversion will fail with an error message. Use a video that has an audio stream.
Can I extract audio from a GIF?
No — GIF files do not contain audio. Use a video file (MP4, MOV, WebM, etc.) as the input.
Video to MP3 vs. Desktop Software
Desktop tools like Audacity or HandBrake can extract audio, but both require installation, configuration, and familiarity with multi-step export dialogs. Online converters often throttle file size or queue you behind other users. FileCrank processes your file locally in the browser — no upload bandwidth wasted, no file-size cap imposed by a server, and no waiting in line.
