Processing Steps

  1. 1. Drop .JSON Files Locally
    Choose JSON (application/json) files from your device. The browser checks their type before processing.
  2. 2. Sonify Locally
    Create an audio representation of the source content.
  3. 3. Save .OPUS or Swing P2P
    Download the .opus output, export a batch ZIP, or choose "Convert & Swing" to transfer it to another device.

Frequently Asked Questions

What does this JSON to OPUS route produce?

Create an audio representation of the source content. The output is a derived view; it does not preserve the complete source file.

Does the .json file leave my device?

The conversion runs in your browser. Files are not uploaded to a conversion server.

Can I process large .json files or batches?

There is no daily conversion quota. Large files and batch size depend on available browser memory and the format engine.
