Why convert audio
Different apps and devices expect different audio formats — converting to MP3 keeps files small and universally playable, while converting to WAV gives you an uncompressed, editing-friendly file.
Good to know
Conversion runs on a browser-based build of FFmpeg that loads the first time you convert a file and stays cached for the rest of your session — every input format can be converted to every output format, the same way a desktop converter would.
Audio Converter FAQ
Is my audio uploaded anywhere?
No. Your file is converted entirely in your browser — nothing is sent to a server.
Which formats can I convert to?
Any of MP3, WAV, M4A, AAC, OGG, or FLAC, in any direction — for example MP3 to FLAC, WAV to M4A, or OGG to AAC.
Why does the first conversion take longer?
The first time you convert a file, your browser downloads a one-time audio conversion engine (a build of FFmpeg compiled for the browser). It's cached after that, so every conversion afterward in the same session starts instantly.
Does converting reduce quality?
Converting to WAV or FLAC is lossless. Converting to MP3, M4A, AAC, or OGG re-encodes the audio at a high bitrate, which is inherently lossy like any compressed-audio encode.
What does the bitrate shown for my file mean?
It's an estimate calculated from the file's size and duration, not read from the file's internal metadata — a simple, reliable stand-in that works the same way across every supported format.
Is it free?
