PDFLince. Privacy first, client side PDF tool
Zero-server processing inside the browser is the clever bit — Web Workers + pdf-lib/PDF.js lets you compress, merge, split and convert large PDFs without uploading sensitive files. The app also supports offline use and multiple languages, but the repo is early-stage with minimal community traction, so it’s useful now for cautious users or integrators rather than a drop-in replacement for mature SaaS players.
