Free online tools that work instantly in your browser. No account required.

40 tools across 8 categories

Webtools is a collection of free browser-based utilities covering text, numbers, colors, code, time, conversions, word games, and random tools. Every tool runs entirely in your browser — your data never leaves your device, and there is nothing to install or configure.

Whether you need to convert a Roman numeral, decode a JWT, check color contrast for accessibility, calculate a percentage, or generate a secure password, you'll find a purpose-built tool here. New tools are added regularly across all categories.

Browser-based tools that just work

All tools on Webtools run directly in your browser using JavaScript. There's no server processing your input, no account to manage, and no data stored anywhere. This makes the tools fast to load and safe to use with sensitive data like passwords or private text.

A tool for every common task

From developers formatting JSON or decoding JWTs, to designers checking color contrast, to writers counting characters or generating placeholder text — Webtools has a dedicated tool for the tasks people search for every day. All free, all instant, all in one place.
