How to use

  1. Add your DTS file

    Drag the DTS file onto the drop area above, or click it to pick a file from your device. You can add several files at once.

  2. Confirm M4A as the output

    M4A is already selected as the output format on this page. You can pick the bitrate — higher keeps more of the sound, lower makes a smaller file.

  3. Run the conversion

    Press the convert button. Audio decodes and re-encodes in your browser — a normal song finishes in a few seconds.

  4. Download the M4A file

    When it finishes, download the M4A file. Converting multiple files gives you the option to download them together as a ZIP.

Frequently asked questions

Is converting DTS to M4A really free?

Yes. DTS to M4A conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.

Are my DTS files uploaded to a server?

No. The conversion runs entirely inside your browser using WebAssembly, so the DTS file never leaves your device. That is also why it works without an internet connection once the page has loaded.

Is there a file size limit for DTS to M4A conversion?

The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
