Essential tools for developers and power users — generate IDs, inspect tokens, build QR codes, test regex, convert timestamps, and more. All processing is client-side.
These tools cover the day-to-day utilities that developers reach for outside the core encode/decode and JSON workflows. Need a fresh UUID for a database migration? Decoding a JWT to inspect its claims? Converting an epoch timestamp to a readable date? Building a QR code for a URL? They're all here — no sign-up, no data sent to a server.
