What is Utility Stones?
The main constraint I set: nothing leaves the browser. No file uploads, no server, no account. PDF merge, image processing, OCR, video-to-GIF — all done via WebAssembly or native browser APIs client-side. Tech behind some of the tools: * PDF operations → pdf-lib + custom worker * Image/video processing → Canvas API + ffmpeg.wasm * OCR → Tesseract.js * QR generation → client-side JS library * Remove background → runs locally in-browser * etc
