Frequently asked questions
- Are my files uploaded to a server?
- No. JadePDF runs entirely in your browser. Your PDF files are read locally from your device and merged with JavaScript, so they never leave your computer.
- How many PDFs can I merge at once?
- There is no hard limit. You can merge as many files as your browser and device memory allow — most users merge dozens of documents without any problem.
- Can I control the order of the merged document?
- Yes. Drag the files in the list to rearrange them before merging. The final PDF follows exactly the order shown in the list.
- Will merging reduce the quality of my PDFs?
