# Video to MP3 Converter — Documentation & FAQ

Documentation for [Video to MP3 Converter](https://www.razi.pro/tools/video-to-mp3) — Extract audio from any video file. Convert MP4, MOV, AVI, WebM to MP3, WAV, AAC, or OGG with custom bitrate settings.

## Frequently asked questions

### How do I extract audio from a video file?

Upload your video file (MP4, MOV, AVI, WebM), select your preferred audio format (MP3, WAV, AAC, OGG) and bitrate, then click 'Extract Audio'. The server will process the video and provide a download link.

### What audio formats are supported?

You can extract audio in MP3 (most compatible), WAV (highest quality, lossless), AAC (great for Apple devices), or OGG (open-source format). Each format has different trade-offs between quality and file size.

### What bitrate should I choose?

128kbps is standard quality, 192kbps offers a good balance of quality and file size, and 320kbps is the maximum quality for MP3. For casual listening, 192kbps is recommended. For professional use, choose WAV format instead.

### What is the maximum video file size?

You can upload video files up to 4MB. Processing is done server-side with FFmpeg, and uploads go through the request body, which is capped at that size. Use the Video Compressor first for anything larger.

### Is the video to MP3 converter free?

Yes — free, no watermarks, no signup and no ads. Fair-use limits apply (currently 10 conversions per hour).
