About pdftheory
Who are we?
pdftheory is a forward-thinking software collective dedicated to building the web's most powerful privacy-first document tools. We are a team of engineers passionate about open web technologies.
What do we do?
We engineer high-performance, client-side PDF utilities that run entirely in your browser using advanced WebAssembly. We simplify complex document tasks without expensive software.
Helping People Globally
pdftheory is designed to be fast, reliable, and secure, handling everything from everyday document tasks to large-scale workflows.
Privacy at the Core
We believe utility shouldn't cost privacy. Our Zero-Upload architecture means we never see, store, or touch your documents—they stay on your device, always.
