What's In It
Seventeen tools, grouped by the kind of job they do. Every one of them works the same way: open it, use it, close it. No sign-up, no setup, no upsell.
Text and Writing
Text Case Converter moves text between uppercase, lowercase, title case, camel case and snake case. Text Statistics counts characters, words and paragraphs, and estimates reading time. Sorter orders lines alphabetically, numerically or by length. Markdown Previewer renders GitHub Flavoured Markdown live as you type.
Time and Dates
World Clock is an interactive globe — spin the earth, flip to a Mercator map, and read live times and timezone regions off it. Timezone Converter lays a full day across several zones on one aligned timeline. Date Difference Calculator measures the gap between two dates, and Unix Timestamp Converter goes between epoch seconds and human-readable dates.
Converting and Calculating
Unit Converter handles length, weight, temperature and volume. BMI Calculator takes metric or imperial input. Percentage Calculator covers plain percentages, changes, and increases or decreases. Foot Size Converter maps shoe sizes across US, UK, EU and centimetres.
Images, Colour, and the Rest
Colour Picker returns HEX, RGB, HSL, CMYK and HSV. Image Converter changes format between PNG, JPG and WebP and resizes on the way through. QR Code Generator turns text or a URL into a code. Morse Code Generator converts in both directions and plays the result back as audio, light or vibration. Spin the Wheel picks something at random when you would rather not decide.
Nothing Leaves Your Device
Every tool runs client-side. There are no accounts, no ads, and no analytics on the tools themselves — the file you convert and the text you paste never reach a server, because there is no server to reach. That is also why it stays fast: the only network request is the one that loads the page.
How It's Built
React 19 and TypeScript on Vite, styled with Tailwind CSS, with Radix UI for the accessible primitives and React Router for client-side routing. Theme switching runs through next-themes, animation through Framer Motion.
The individual tools lean on focused libraries rather than reinventing things: dayjs and date-fns for time, marked with remark-gfm for Markdown, qrcode.react for codes, react-colorful for colour, browser-image-compression for resizing, Leaflet for the map behind the world clock, and DOMPurify to sanitise anything rendered as HTML.
Where To Find It
