I built 185 free browser tools that never upload your files

Why browser-based? Every other "online tool" site uploads your PDFs and images to their server for processing. That means: Your sensitive documents sit on someone else's machine Processing speed depends on their server load File size limits, watermarks, or forced signups I built everything using client-side processing — Canvas API, pdf-lib, Tesseract.js (WebAssembly), and more. Your files literally never leave your device.
