Are my JSON files uploaded anywhere?

No. This conversion runs entirely inside your browser, so the file never leaves your device. You can confirm it yourself: open the network tab of your browser's developer tools and watch that nothing is sent while the file converts.

Is converting JSON to INI free?

Yes, without a limit on how many files you convert and with no watermark on the result. Files up to 100 MB are covered by the free plan.

Does converting JSON to INI lose quality?

JSON and INI describe content in fundamentally different ways, so the conversion is a reconstruction rather than a copy. The result is faithful, but not byte-for-byte equivalent. INI has no nesting. Structures deeper than one level are flattened into dotted keys.

Do I need to install anything to open INI files?

No installation is needed for the conversion itself — it runs in the browser you already have. Opening the INI afterwards needs whatever software normally handles INI Configuration on your device.

What JSON and INI are for

The data format of the web. Nested structures, read by every programming language.

Sections and key-value pairs. The oldest configuration format still in daily use.
