About these tools

These developer utilities — JSON Forge, Base64 encoder/decoder, Regex Tester, UUID Generator, Hash Generator, and Text Case Converter — are built for speed. Open a tool, paste your input, get your output. No accounts, no rate limits, and no waiting for a round-trip to a remote server.

Every computation runs inside your browser tab using JavaScript, which makes them safe for sensitive work: API tokens, JWT payloads, database snippets, and config fragments never leave your machine. Hash a string, encode a payload, or debug a regex pattern without worrying about where your data ends up.

Common questions

• Is it safe to paste API keys or sensitive code snippets?
  Yes. All processing happens locally in your browser — nothing is uploaded to any server. Your input is never transmitted anywhere.
• Do these tools work offline?
  Once the page has loaded, the computation is entirely local, so the tools continue to work even if your internet connection drops mid-session.
