FAQ
Can I merge PDF files without uploading them?

Can I change the order before merging PDFs?
Yes. Add your PDFs, move them into the right order, and the merged file will follow that same sequence.
Does this PDF merger preserve the original pages?
Yes. The tool combines existing PDF pages into a single document while preserving the page content from the source files. It is designed for merging, not compressing or editing.
Does this online PDF merger work on phone and desktop?
