About Webtools
Free, instant, browser-based utilities for everyday tasks.
What is Webtools?
Webtools is a collection of free, browser-based utility tools covering text manipulation, number calculations, color conversion, code formatting, date and time handling, unit conversion, word games, and random generation. Every tool runs entirely inside your browser using JavaScript — your data is never sent to a server, and nothing is stored or logged.
The site currently offers 40+ tools across eight categories. Tools are purpose-built for the tasks developers, writers, designers, and everyday users search for most: formatting JSON, converting between letter cases, checking color contrast for accessibility, decoding JWTs, calculating dates, and dozens more.
Who built Webtools?
Webtools was built and is maintained by Bart Klein Reesink, a developer based in the Netherlands. The project started from a simple frustration: too many "free online tools" sites are slow, ad-cluttered, or require an account for tools that should just work. Webtools is the answer to that — clean, fast, no friction.
Why is it free?
These tools are genuinely free with no registration, no paywalls, and no rate limits. The goal is simple: if a tool solves a common problem, it should be available to everyone instantly. Webtools is a passion project — the site covers its own hosting costs and exists because building useful things is worthwhile.
How are the tools built?
The site is built with Laravel and Livewire on the backend, with Alpine.js and Tailwind CSS on the front end. Most tools run entirely client-side via Alpine.js reactive bindings — the server is only involved for rendering the initial HTML. This means the tools are fast, work without JavaScript frameworks, and your input stays local.
