Audio Converter

About this tool

This free audio converter changes an audio file from one format to another — MP3, M4A (AAC), WAV, OGG or FLAC. Upload your file, choose the output format and quality, and download the converted audio.

Everything runs in your browser — your file is never uploaded, so it stays private and there are no size limits from a server.

Features

• Convert to MP3, M4A, WAV, OGG or FLAC
• Choose the bitrate (up to 320 kbps) for compressed formats
• Lossless output with WAV and FLAC
• Also extracts audio from a video file if you drop one in
• Preview both the original and the result before downloading
• 100% in-browser — nothing is uploaded

Common uses

• Convert M4A or WAV to MP3 for wider compatibility
• Turn a big WAV into a smaller MP3 or M4A
• Get a lossless FLAC from your source audio
• Make an OGG for the web or games

A note on the engine

Conversion uses an in-browser audio engine that downloads once (about 30 MB) the first time you use it. After that it works offline, and you can switch tabs while it runs — just keep this one open.

How to use it

• Upload an audio file — click the upload area or drag it in
• Choose a format — MP3, M4A, WAV, OGG or FLAC
• Set the quality — pick a bitrate for compressed formats
• Convert & download — play the result, then save it
