Why “private” actually means something here
Every popular PDF site works by uploading your document to their server. Their privacy is a policy — a promise that could change or be breached. Ours is an architecture: this site is static files plus your browser. There is no endpoint that can receive a document, and our security policy blocks the site from talking to any other server. If you handle contracts, medical records, HR files or client data, that difference is the whole point.
