About PDFKit
What is PDFKit?
PDFKit is a free, open collection of online PDF tools designed to handle everyday document tasks. Whether you need to merge files, compress a large PDF, add a signature, or convert between formats, PDFKit has you covered — no account required.
Privacy First
Unlike most online PDF services, PDFKit processes every file entirely inside your browser. Your documents are never uploaded to a server. There is no cloud storage, no third-party processing, and no data collection. Once you close the tab, your files are gone.
How It Works
PDFKit uses modern web technologies — including WebAssembly and the browser's built-in APIs — to perform all PDF operations on the client side. This means your files stay on your device from start to finish. No internet connection is even required after the page loads.
Always Free
Every tool on PDFKit is completely free to use with no hidden limits. There are no watermarks, no file-size caps, and no daily usage restrictions. We believe essential document tools should be accessible to everyone.
Our Mission
We built PDFKit because working with PDFs should not require expensive software or trusting a stranger with your sensitive documents. Our goal is to provide the most comprehensive, privacy-respecting PDF toolkit on the web.
