    JW Tool Box▲5

    I got tired of "free" online tools that may steal data or force you to create an account. So I built a suite of 40+ utilities that run entirely in your browser (client-side only). - No server uploads (Privacy first) - No login required - No paywalls It includes PDF tools, image converters (HEIC/WebP), and developer utilities. Built with React, Vite, and WASM. Feedback welcome!
