How to combine multiple PDFs into one

Combining files into one PDF is the tidiest way to send a set of related documents: an application pack, a report with appendices, a batch of receipts.

Order matters

Add files in the order you want them to appear; the merge preserves that sequence. Rearrange first if needed.

Mixing in images

Many workflows need a scan or photo between PDFs. Convert images to PDF first, or use a tool that accepts both.

Keep bookmarks in mind

Simple merges may drop source bookmarks. If navigation matters, add fresh bookmarks or a contents page after merging.
