Insert Pages in PDF

Most documents need changing after they are finished rather than before. A signed page comes back and has to go into the contract. A revised appendix replaces the old one. A cover sheet is required by the portal you are submitting to. An addendum has to sit with the clause it amends rather than at the end.

Without a tool for this the usual workaround is to split the document, merge three pieces back together, and hope the order survived. Inserting does it in one operation: pick the point, pick the pages, save. The rest of the document is untouched.

It also handles the reverse-direction case that trips people up — putting something at the very front. A cover page, a compliance declaration or a transmittal sheet belongs before page one, which merging can do only if you happen to load the files in the right order.

Pages can come from another PDF, either all of it or a specific range. Taking a range matters more than it sounds: the signed page you need is usually page 7 of a scan that also contains six pages you do not want, and being able to say so avoids extracting it into a temporary file first.

Blank pages are the other option, and they have real uses beyond padding. Duplex printing wants an even page count, so a document ending on an odd page needs one blank at the back. Chapters that must open on a right-hand page need a blank verso before them. Printed handouts often want a blank facing page for notes.

Whatever you insert keeps its own page size and rotation. Mixing an A4 document with Letter-sized inserts produces a file containing both, which is correct — scaling one to match the other would alter margins and could crop content near the edge.

The pages themselves are copied without modification, so nothing about their appearance changes. What changes is position, and anything that depended on position now needs attention.

Printed page numbers are ink on the page rather than a live count, so a document numbered 1 to 20 with three pages inserted at page 5 now reads 1, 2, 3, 4, 5, 5, 6, 7, 6, 7, 8 and so on. Add Page Numbers over the finished document renumbers it properly. Bookmarks pointing past the insertion point are off by the number of pages added, and Edit Bookmarks repoints them.

Neither is fixed automatically, because both fixes involve choices — whether the inserted pages should be numbered at all, whether they deserve their own bookmark — that only you can make. Doing the insert first and the tidying second is the reliable order.

Inserting is for adding pages at a chosen point inside a document. Merge PDF is for joining whole files end to end, and is the better tool when you are assembling several documents rather than amending one.

There is no replace operation, because it is two steps that are clearer done separately: delete the pages you are replacing with Delete Pages, then insert the new ones at that position. Doing it in that order means you can check the deletion looked right before adding anything.

If the material you want to insert is an image rather than a PDF — a photographed signature page, a scanned receipt — Merge PDF & Image wraps pictures onto pages of their own, and the result can then be inserted here.
