We're the team behind PDFUp, ResumeUp, and ImageUp. We build the most honest tools on the internet - free, private, and lightning fast.
For years, managing PDF files online meant making a dangerous compromise. You either had to download expensive, bloated desktop software, or you had to upload your highly sensitive documents to random cloud servers just to merge or compress them.
Tax forms, medical records, and legal contracts were being freely transmitted across the internet and stored in third-party databases, often without the user realizing the immense privacy risks involved.
We built PDFUp with a strict Offline-First Architecture. By leveraging modern web technologies (like WebAssembly and advanced JavaScript), we moved the entire processing engine from our servers directly into your web browser.
When you use PDFUp, your files never leave your computer. The merge, split, compress, and edit functions happen entirely inside your device's memory. This guarantees absolute data privacy and results in lightning-fast processing speeds, unconstrained by your internet connection.
