How to Convert Any Audio File to MP3

Convert FLAC, WAV, OGG, AAC, and more to MP3 instantly in your browser. Free, private, no signup.

MP3 remains the most universally compatible audio format, supported by virtually every device, app, and platform. Converting to MP3 ensures your audio files play anywhere.

ConvertCraft's Audio Converter handles the conversion entirely in your browser using WebAssembly-powered processing. Your audio files stay on your device throughout.

Simply open the Audio Converter, drop your audio file (FLAC, WAV, OGG, AAC, M4A, WMA, or more), select MP3 output, choose your desired bitrate, and convert.

For music, 256 kbps or 320 kbps is recommended. For podcasts and spoken word, 128 kbps provides excellent quality at a smaller file size.

Batch conversion is supported — convert multiple files at once with the same settings applied to each.
