Small utilities that save a trip to the terminal: generate strong random passwords, encode or decode Base64 text, convert colors between HEX, RGB and HSL with a live preview, switch number bases from binary to hexadecimal, calculate aspect ratios for images and video, generate SHA hashes, create UUIDs, convert Unix timestamps to readable dates, format or validate JSON, and encode or decode URLs.
Every tool runs client-side in JavaScript, so pasted code, keys, tokens and data never leave your browser or touch a server. Results update instantly as you type, with the same reliability you'd expect from a command-line tool but without opening a terminal or installing a package.
