About PDF Tools Pro

PDF Tools Pro was built with one principle: your files should never leave your browser.

Unlike other PDF tools that upload your documents to their servers, we process everything locally using WebAssembly and modern browser APIs. This means your sensitive contracts, personal documents, and business files stay private.

Why We Built This

We were tired of uploading sensitive documents to random servers just to merge two PDFs or add a signature. We built PDF Tools Pro to solve this — a complete PDF toolkit that respects your privacy.

Our Principles

• Privacy First: Client-side processing means zero data collection.
• No Account Required: Start using tools immediately. Sign up only if you want history.
• No Subscriptions: Essential tools are free forever. Power features are a one-time purchase.
• Open Source Friendly: We use and contribute to open-source PDF libraries.
