Frequently Asked Questions

Are these tools free to use?

Yes, all tools on this page are completely free. No account, sign-up, or payment required. They run entirely in your browser — your data never leaves your computer.

Do you store my data?

No. All processing happens locally in your browser. We never send your JSON, API requests, or QR code data to any server. Your privacy is guaranteed.

Can I use these tools offline?

The QR code generator, JSON tools (to-ts, compare), API code generator, and Markdown to HTML converter work entirely client-side. The Movie Finder requires an internet connection to fetch movie data from TMDB.

What languages/programs can I generate API code in?

The API Code Generator supports cURL (shell), fetch() (JavaScript/browser), axios (Node.js/browser), and jQuery AJAX. More languages coming soon.
