Frequently asked questions
- How many PDFs can I merge?

- Can I reorder the files before merging?
- Yes. After adding files you can drag them into any order before clicking Merge.
- Are my PDFs uploaded to a server?
- No. Merging happens entirely in your browser, so your documents stay private.
- Will the merged PDF have a watermark?
- Never. The output is a clean, standard PDF with no added branding.
