About AlienWeb

What we do

AlienWeb is a free collection of browser-based tools for writers, developers, students, and anyone who needs a quick answer without installing software or creating an account. From word counters and text formatters to JSON validators, password generators, and everyday calculators like BMI, age, and loan EMI — every tool is designed to solve one job well.

Why we built it

Most "free tool" sites bury a simple task behind pop-ups, forced sign-ups, or slow, ad-choked pages. We wanted the opposite: open a tool, get your answer in seconds, move on. AlienWeb runs entirely in your browser using plain JavaScript — there's no server processing your text or your data, and no account required for any tool on the site.

How the tools work

Every calculator, converter, and generator on AlienWeb runs client-side. That means your input — whether it's a paragraph of text, a password you're generating, or numbers for a calculation — is processed on your own device and never transmitted to our servers. We believe a "free tool" shouldn't come at the cost of your privacy.

Support the site

AlienWeb is free to use and supported by ads shown alongside the tools. Ads are non-intrusive and clearly labeled — no fake download buttons, no pop-ups, no interstitials that block the tool you came for.
