About FoundryPDF
FoundryPDF is a workshop of small, sharp PDF tools. Every one of them runs entirely in your browser — your files are never uploaded, queued, or stored on a server.
Why it exists
Most online PDF tools quietly upload your documents to a server before touching them. That is fine for a blank form — and unacceptable for a contract, a medical record, or a tax return. We built FoundryPDF so the default is safe: the work happens on your device, and a live “Network · 0 uploads” counter on every tool page proves it.
How it works
The tools are built on mature, audited browser libraries that read and write PDF structure locally. Nothing about your document ever crosses the network — you can even load a tool page, go offline, and keep working.
What's free and what's Pro
The core tools are free with no account. NanoPDF, the AI editor, uses paid model credits — that is the only feature that talks to a server, and only after you choose to send a file.
