Our Mission
Most online tools send your files to a remote server. This creates privacy risks — especially for sensitive documents like contracts, invoices, ID documents, tax files, and personal photos. ThePDFTools was built to solve this: every tool processes files locally on your device using modern browser technology including WebAssembly, the Canvas API, and the Web Crypto API.
We believe productivity tools should be accessible to everyone — students, freelancers, small businesses, and developers in every country — without paywalls, subscriptions, or forced account creation.
How It Works
PDF tools use WebAssembly-compiled PDF libraries that run directly in your browser tab. When you compress a PDF or merge files, the processing happens on your device — the same way a desktop app works, but without installation.
Image tools use the HTML5 Canvas API and, for AI features like background removal and upscaling, ONNX Runtime Web — a machine learning runtime that executes AI models entirely client-side.
Developer tools use JavaScript built-in APIs. JSON formatting, Base64 encoding, URL encoding, regex testing, and timestamp conversion are all pure browser operations with no server involvement.
