Security Architecture
Browser-Based Processing
When you add a file to EasyPDFMerge, we use the File API to read the data into your computer's RAM. We do not use an "Upload" function because there is no server destination for your data.
The PDF-Lib Engine
We utilize pdf-lib, a powerful JavaScript library that manipulates PDF binary structures directly. The merging happens in a sandbox environment provided by your web browser, isolated from other tabs and your file system.
"You can literally disconnect your internet after this page loads, and the PDF merger will still work perfectly. That is our privacy guarantee."
