Questions

Are the tools really free?

Yes. Every tool is free with no sign-up and no usage limits. The site is supported by advertising.

Is my text uploaded to a server?

No. Every tool runs in your browser with JavaScript, so the text, JSON or data you paste never leaves your device. The tools keep working if you go offline after the page loads.

Do the tools work on my phone?

Yes. Every tool is designed for touch screens as well as desktops, with large controls and one-tap copy.
