Which array syntax should I use?

Short [] syntax is standard on PHP 5.4+ and is easier to read. Use array() only when targeting very old runtimes.

How are JSON nulls handled?

They become PHP null, or you can drop those keys entirely with the toggle.

Are large numbers safe?

Values beyond PHP integer range are emitted as-is; check them manually if precision matters.

Is my data uploaded to a server?

No. This tool runs entirely in your browser using standard web APIs, so your input never leaves your device and nothing is logged or stored on our servers.

Does it work offline and on mobile?

Yes. Once the page has loaded it keeps working without a network connection, and the layout is responsive so it stays usable on phones and tablets.
