# ClientPDF

> Free, browser-based PDF tools. Every operation — merge, split, compress, rotate, watermark, and more — runs entirely client-side using pdf-lib in JavaScript. No file is ever uploaded to a server; nothing to sign up for.

ClientPDF is a static site (GitHub Pages) offering 25 single-purpose PDF tools plus troubleshooting guides and comparison pages against upload-based competitors (Smallpdf, iLovePDF, PDF2Go). All processing happens in the user's browser; files never leave the device.
