About utilitech

utilitech brings together the small tools developers reach for every day — generating IDs and passwords, formatting JSON, signing and decoding tokens, hashing, encrypting, converting documents and images, naming database columns and more — in one fast, clean place.

Our principles

• Private by design. Every tool runs locally in your browser. The text, files, keys and tokens you work with are never uploaded to our servers.
• Free to use. No sign-up and no paywalls. The site is supported by unobtrusive ads and by people who choose to buy us a coffee.
• Fast and focused. Each tool does one job well, gives instant results as you type, and stays out of your way.

What's inside

20 tools across 7 categories: security, naming, encoders, generators, converters, web and mock data. Browse all tools.
