Universal audio converter

ANY → ANY

Converts between MP3, WAV, OGG, FLAC, M4A, AAC, WMA, and MPEG-family formats, in any direction. Because supporting every format genuinely requires real decoding that browsers can't do on their own, this tool uses a secure server step rather than running fully in your browser tab.

Drag audio files here, or click to browse

Accepts MP3, WAV, OGG, FLAC, M4A, AAC, WMA, MPEG/MPG/MP2, AIFF, Opus, AMR, AC3 · up to 20 files, 300MB total, 100MB per file

Files are uploaded over an encrypted connection, processed, and deleted from the server immediately afterward. Nothing is kept or shared.

How this tool works

Supporting real any-format-to-any-format conversion needs actual audio decoding that browsers can't do reliably for every codec, so this tool uses a secure server step: your file is uploaded over an encrypted connection, converted, sent back for download, and deleted immediately — it's never stored, logged, or used for anything else.

The Universal Audio Converter

Converts between MP3, WAV, OGG, FLAC, M4A, AAC, WMA, and MPEG-family audio formats, in any direction — unlike Quikbench's other audio tools, which each handle one specific pair.

Single files or batches

Convert one file at a time with its own format dropdown, or queue multiple files and send them all to the same target format in a single batch, with a zip download when you're done.

Why this uses a server

Every other approach that runs fully in-browser is limited to the handful of codecs a browser can natively decode. Genuinely supporting any format — including WMA and legacy formats browsers have never supported — needs a real decoding engine, so this tool briefly touches a server, and only for as long as it takes to convert your file.

Frequently asked questions

What audio formats can I convert between?

Input accepts MP3, WAV, OGG, FLAC, M4A, AAC, WMA, MPEG/MPG/MP2, AIFF, Opus, AMR, AC3, and WEBA. Output can be MP3, WAV, OGG, FLAC, AAC, M4A, or WMA.

Is this free to use?

Yes, completely free with no account required and no watermarks.

Why does this tool use a server instead of running fully in my browser?

Browsers can only decode a handful of audio codecs natively. To genuinely support any format to any format, this tool uses a secure server step: your file is uploaded over an encrypted connection, converted, and deleted immediately afterward.

Can I convert multiple files in one session?

Yes — queue up to 20 files (300MB combined, 100MB per file) and convert them all to the same target format in a single batch, then download everything as one zip file.

Is there a file size limit?

Each file can be up to 100MB. Batches are capped at 20 files and 300MB combined.

Does this work on mobile?

Yes, it works on any device with a modern browser, including phones and tablets.
