Online Audio Converter
Convert audio files in the browser using only the formats and encoders that are actually implemented.

What this tool actually does
Convert audio files in the browser using only the formats and encoders that are actually implemented.
Writes only WAV, AIFF and MP3, the three formats with a real encoder in this build.
Handles several files at once: the view keeps a file list and shows how many are loaded.
Everything runs in the browser - the file is read locally, decoded and downloaded again, with nothing uploaded.
Real-world use cases
What people actually solve with this converter before they play live.
Prepare tracks before a DJ set.
Fix or process files without opening a full DAW.
Keep the workflow focused on the specific task instead of a general-purpose editor.
