About PDFKit

PDFKit provides a complete suite of 8 free online PDF tools that work entirely in your browser. Unlike traditional PDF services, your files are never uploaded to any server — all processing happens locally on your device using modern web technologies.

Complete Privacy

Privacy is at the core of everything we do. When you use PDFKit, your files never leave your computer. There are no uploads, no server-side processing, and no temporary storage of your documents. Your PDFs, images, and other files remain entirely under your control at all times.

This is possible because all of our tools are built using client-side JavaScript libraries, primarily pdf-lib for PDF manipulation and pdfjs-dist for PDF rendering. These libraries run directly in your web browser, meaning no data ever needs to be sent to a remote server.
