  3. Put them in order

    Drag the files by their handles. Top to bottom is the final page order. Tap Edit to remove one.

    Step 3: Put them in order

Check page order and save a separate copy

Files combine top to bottom. Every page keeps its place within its own file.
Page countThe combined PDF should have exactly the pages of all files added together.
First and last pagesCheck where one file ends and the next begins.
OriginalsKeep the original files until you’ve checked the combined one.

What to do with locked or unsupported files

Reduce the combined PDF before sharing

Combining files adds their sizes together. If the result is too large to email, compress it once, after merging. See how to compress a PDF on iPhone.
