Convert audio in three steps

A free converter for any audio file — change the format to whatever you need, all on your device.

  1. Step 1

    Add your audio

    Drop in a WAV, M4A, AAC, OGG, FLAC, WMA or MP3 file — one or a batch.

  2. Step 2

    Choose the output

    Pick MP3, M4A, OGG, or lossless FLAC/WAV, set the quality, and hit Convert.

  3. Step 3

    Download your file

    Save each result or grab them all as a Zip. Your originals stay untouched.

Any format to any format

Different apps want different audio formats. This converter gives you whichever one you need.

Standardise on MP3

Turn a mix of formats into MP3 so everything plays everywhere.

Need lossless?

Export to WAV when you want uncompressed audio.

Match an app

Some tools only accept one format — convert to fit.

Shrink or expand

Compress to MP3 to save space, or convert up to WAV for editing.

Batch convert

Drop many files and convert them all in one run.

Then transcribe it

Convert to MP3, then transcribe the audio with SlayScribe.

Why use an online audio converter

Audio comes in a dozen formats and each plays in some places but not others. An audio converter is the common ground: drop in whatever you have and get out the format you actually need — MP3 for universal playback, WAV for editing, M4A or OGG for efficiency. Because it runs in your browser, your audio stays private and never touches a server.
