How to Merge PDF Files
Combine several PDF documents into one file while controlling their order.
Choose files and order
Start by selecting the PDF files you want in the final document. Review their order before processing because the combined PDF follows that sequence.
Check the result
After merging, confirm the expected page count and sample the transition between source documents. Large files may require more browser memory.

If you need to reorder individual pages after merging, use Organize PDF. If you only need particular pages, Extract Pages may be more direct.
