About Us

PDF Toolbox is a privacy-focused online PDF processing platform. We firmly believe that users' data rights should be respected, and file processing should not come at the cost of privacy.

Our Philosophy

With the widespread adoption of cloud computing today, most online tools upload user files to remote servers for processing by default. While this is technically simple, it introduces risks such as privacy leaks, data misuse, and cross-border data transfers. We chose a more difficult technical path — running all processing logic in the user's browser to ensure files never leave the device from start to finish.

Technical Features

• Pure frontend processing: all PDF operations are completed locally in the browser
• No registration required: open the page and use it immediately, no personal information collected
• Instant release: files are immediately cleared from memory after processing
• Open-source stack: built on mature open-source libraries such as pdf-lib and pdf.js
