About ClientPDF

Free, private, and secure PDF tools that work entirely in your browser

ClientPDF is a free, browser-based PDF toolkit that provides 10 essential PDF tools — including merge, split, compress, convert, rotate, delete pages, reorder pages, and watermark. All processing happens 100% client-side using JavaScript and WebAssembly. Your files never leave your device. No uploads. No accounts. No tracking.

ClientPDF is designed for anyone who needs to work with PDFs quickly and privately. Unlike cloud-based PDF tools like iLovePDF, Smallpdf, or Adobe Acrobat Online, ClientPDF processes everything locally in your web browser. This means zero server-side file handling and complete data privacy.
