On iPhone, Markup can draw on a page but cannot change a single existing word. That is why people end up searching for a way to merge a PDF properly.

Merging keeps fonts, links and form fields intact instead of flattening everything into images, provided the tool combines rather than re-renders.

Open Safari and choose the file from Files, iCloud Drive or a saved mail attachment. Then work through the same steps as anywhere else:

Open the first document, then insert the others in the order you want them.

Drag pages in the page view to fine-tune the order and rotate anything scanned sideways.

Delete blank pages the scanner added and duplicate any page you need twice.

Export the combined file, compressing images if the result is large.

When you export, the iOS share sheet opens so you can save to Files, AirDrop it or send it straight to Mail. PDF, PNG and JPG are all available.

Doing the tidying before export means writing the file once rather than three times.
