FreeToolWise

Most online utility websites are cluttered with aggressive paywalls, slow servers, and forced signups just to convert a PDF or format JSON. FreeToolWise is a free, privacy-first hub of 100+ browser-based tools including image optimization, PDF converters, JSON validators, text formatters, and calculators. How it was built: - Tech Stack: Next.js (App Router), TypeScript, and Tailwind CSS. - Privacy & Speed: Heavy operations (image and file processing) run client-side in the browser using WebAssembly and Web Workers so user data never leaves their machine. - Zero forced signups, zero paywalls.
