How to use the Audio Format Converter
- Add one or more audio files (or videos to extract audio).
- Choose output format, bitrate, sample rate and channels.
- Press Convert and download each file or a ZIP.
Why creators use it
- Turn phone voice memos (M4A/AMR) into MP3 or WAV for editing.
- Make Opus or OGG versions for web players.
Good to know
- Uses FFmpeg compiled to WebAssembly (about 30 MB, downloaded once from jsDelivr and cached). It runs on one CPU core, so long or high-resolution videos take a while.
- Up to 10 files and 500 MB per batch (less on phones).
- Bitrate does not apply to WAV or FLAC (lossless).
- Only process media you own or have permission to use.
Frequently asked questions
