About Audio to MP3 Converter
How it works
This tool converts various audio formats to MP3 directly in your browser using FFmpeg.wasm:
- The tool downloads the audio file from the URL you provide
- Using FFmpeg (compiled to WebAssembly), it processes the audio in your browser
- The converted MP3 file is created and made available for download
Supported Formats
This tool can convert most audio formats to MP3, including:
- WAV files
- AAC audio
- M4A files
- FLAC files
- OGG audio
- And many more formats supported by FFmpeg
Limitations
- CORS restrictions may prevent downloading from some websites
- Only works with modern browsers that support WebAssembly
- Large audio files may require significant memory and processing power
- Audio quality depends on the source file quality
Troubleshooting
CORS Errors: If you see CORS errors, the website is preventing direct access to their audio files. Try using a browser extension that disables CORS for testing purposes.
Memory Issues: If converting a very large audio file, your browser may run out of memory. Try a shorter or lower quality version of the audio.
