Frequently asked questions
- How many PDF files can I merge at once?
- You can merge as many files as your device’s memory can comfortably handle, since everything is processed locally rather than on a shared server.
- Will merging change the formatting of my pages?
- No. Each page keeps its original size, orientation, and content — merging simply combines the page sequences into one document.
- Are my files uploaded to combine them?
- No. The merge happens entirely in your browser using pdf-lib; nothing is sent to a server.
