Not a hack. Not a breach. He just needed to read an API response — the kind of thing you do fifteen times a day without thinking twice. He pasted it into the first result that came up on Google, clicked format, read what he needed, and closed the tab.

Three weeks later, HR called him in.

That JSON payload contained internal customer records. The tool he used logged everything server-side. Their terms of service said so — buried in paragraph eleven of a privacy policy nobody reads. His company's IT audit found it. He was let go that afternoon.

He wasn't careless. He wasn't incompetent. He was a good developer doing a routine task on a Monday morning.

I thought about that for a long time.

Because here's the thing — I do the same thing. Every single day. I paste JSON, CSV, XML, tokens, logs. I need to format it, decode it, transform it. And every tool I found online was either behind a paywall, running on someone else's server, or both.

You hit "Format" and you have absolutely no idea what happens next. Does it get logged? Stored for thirty days? Indexed? Sold to a data broker? The little spinner just spins and you trust it.

I stopped trusting it.

So I built this.

Every single tool on this site runs entirely inside your browser. When you hit "Transform", your CPU does the work. Your RAM holds the data. Nothing leaves your machine — not to my server, not to a cloud function, not anywhere. There is no server to log your data because there is no server involved at all.

You can verify this yourself right now. Open DevTools, go to the Network tab, paste something sensitive, and click Transform. Watch the network requests counter stay at zero. That is the only guarantee worth trusting.

No account required. No sign up. No "delete after 24 hours" promise that you're just supposed to believe. You can use it on an air-gapped machine. You can use it without an internet connection after the page has loaded. That is how local it is.
