Private PDF tools that stay on your device

Incognito PDF is a free browser workspace for everyday PDF tasks. Processing happens locally with MuPDF WebAssembly, so contracts, IDs, and work files do not need to leave your computer.

Built for privacy

Documents, passwords, extracted text, queries, embeddings, and chats are processed in browser memory. Incognito PDF does not use a document-processing server. The production site may record anonymous page-view analytics from the host; document content is never sent.
