About
Free, privacy-first browser tools for everyone.
isrange.com is a collection of free online tools built for students, writers, developers, and anyone who needs quick answers without signing up or downloading software. Our tools run entirely in your browser — your data never leaves your device unless absolutely necessary (like looking up an IP address, which requires a network call by nature).
We started with a simple question: "What is my IP address?" — and grew from there into a full suite of text processing, file conversion, and developer utilities.
We currently offer 15+ free tools across three categories:
Every tool is free to use, works on desktop and mobile, requires no account or sign-up, and respects your privacy by processing data locally whenever possible.
isrange.com is built with Next.js and deployed globally on Cloudflare's edge network, which means the site loads fast regardless of where you are in the world. We use Tailwind CSS for styling and keep our JavaScript bundle as small as possible by lazy-loading heavy libraries only when you actually use a tool that needs them.
