Tools that fit snugly

Toolsnug is a collection of practical, no-fuss tools that fit snugly into the small calculations, conversions, and text or data jobs most people need at some point but rarely want to do by hand. The math section covers everyday arithmetic — percentages, ratios, fractions, tip splitting — plus unit converters for length, weight, volume, temperature, speed, area, pressure, and energy. The design section has colour pickers, type scales, contrast checkers, and SVG utilities. And the developer category rounds things out with encoders, hashers, JSON and regex playgrounds, password generators, and a growing set of everyday code utilities.

Every tool on Toolsnug runs entirely in your browser. The numbers, text, and files you feed into a tool stay on your device — nothing you enter into a tool is transmitted to any server. There are no accounts, no cookies, no cross-site tracking, no advertising trackers. The only telemetry is a privacy-preserving page-view counter that works without cookies and can't identify individual visitors — full detail in the privacy policy.

The site loads quickly because it is built as static HTML with a small amount of client-side JavaScript, and it works offline once the page has loaded. If you are on a slow connection or a mobile network, you will still get a usable result without waiting. Accessibility is a first-class concern: every tool is keyboard- navigable, screen-reader-tested, and respects your operating system's motion and colour-scheme preferences. The goal is a place you can actually trust to give you the answer you need without making you sit through an ad or hand over your email address.
