About UseToolz

UseToolz started with a simple frustration: formatting a bit of JSON, testing a regex or generating a strong password shouldn't mean wading through pop-ups, cookie walls and pages heavier than the task itself. So we built the utility site we wanted to use ourselves.

What Makes UseToolz Different

• Everything runs in your browser. None of the tools sends your input to a server — your code snippets, passwords and text are nobody's business but yours.
• Explanations, not just output. Every tool page documents how the format or algorithm works, walks through a worked example, and answers the questions people actually ask.
• Fast and free. Static pages, minimal JavaScript, no sign-up, no paywall. The site is funded by unobtrusive advertising.

How the Tools Work

Each tool is a small, focused utility that does one thing well — from JSON formatting and Base64 encoding to cryptographic hashing and password generation. Where security matters, we use the browser's native Web Crypto API rather than rolling our own — the password generator, for example, draws from crypto.getRandomValues, not Math.random.

Who Is Behind This?

UseToolz is an independent project, built and maintained by a solo developer. Full legal details are on the imprint page.
