supereasy.toolsAbout supereasy.tools
supereasy.tools is a collection of free, browser-based utilities built by a small team of web developers and UI designers. Every tool runs entirely in your browser — no file uploads, no accounts, no server processing of any kind.
Why we built this
Working on design systems, CSS theming, and frontend development, we kept reaching for heavyweight desktop apps or server-side tools for tasks that a modern browser can handle natively and instantly. A color palette extractor, a JSON formatter, a Base64 encoder — none of these need a server. We built supereasy.tools so that these tasks are fast, private, and always available in a browser tab.
Our background
- CSS color systems — HEX, RGB, HSL, and modern color spaces including OKLCH and Display P3
- Browser APIs used for in-browser processing: the HTML5 Canvas API, Clipboard API, and File API
- UI design workflows in Figma, including design token systems and component libraries
- Web performance, Core Web Vitals, and static-site architecture
Why we include OKLCH
OKLCH is the most perceptually uniform color space available in modern CSS. Unlike HSL, where two colors at the same lightness value can look visually very different, OKLCH maps lightness to how human vision actually works — making it far more predictable for building accessible, consistent color scales. It is supported natively in all modern browsers as a first-class CSS color function (CSS Color Level 4) and is increasingly used in design systems and Tailwind CSS. We include OKLCH output in our color tools because it is the format designers and developers will increasingly reach for.
