Audio Converter
About this tool
What you provide
- One or more audio or video files (MP3, M4A, WAV, MP4)
- An output format: MP3 or M4A
- A bitrate: 192, 128 or 96 kbps
What you get
- A converted MP3 or M4A file for each input, saved one at a time
Limits
- The conversion runs on your device, so your files are never uploaded.
- The audio is re-encoded, so converting an already-compressed file can lose a little quality.
- Large files depend on your device's memory.
How to use it

Add your files
Drop one or more audio or video files on the dropzone, and use Add more files to extend the list.
-
Choose the format
Pick MP3 or M4A as the output for every file in the list.
-
Choose a quality
Pick High, Medium or Small — the setting is the bitrate the audio is re-encoded at.
