Insert Pages into PDF
Insert blank pages or pages from another PDF anywhere: at the start or end, before or after a page, after every page or every N pages. No upload.
Sometimes a PDF needs room: a blank page before a new chapter, a separator after every invoice, blank backs so a double-sided print does not run two documents together, or the pages of a second PDF slotted into the middle. This tool inserts blank pages or pages from another PDF at the start, at the end, before or after any page, after every page or after every N pages. The original pages are untouched and the work happens in your browser.
How to use this tool
- Choose the PDF to add pages to.
- Pick blank pages (and how many each time) or pages from another PDF (all or a range).
- Choose where: start, end, before or after a page, after every page, or after every N pages.
- Download the new PDF and check the new order shown.
Formula
Insertion points are listed by the page they follow: "after every page" gives 1, 2, …, n; "after every N pages" gives N, 2N, … up to n. New pages are inserted from the last point to the first, so the earlier positions do not shift while inserting.
Blank pages take the size and orientation of the page they follow (or the first page when inserting at the start), unless you choose A4 or Letter.
Example
A 3-page PDF with "After every page" and one blank page each time becomes 6 pages: 1 + 2 + 3 +, so every page lands on the front of a sheet in double-sided printing. Inserting pages 1–3 of another PDF after page 1 gives 1 + + + 2 3.
Frequently asked questions
Does inserting a PDF many times make the file huge?
No. Each inserted page is its own page, but fonts and images are shared between the copies, so the file grows only a little per copy.
Can I insert a blank page in landscape?
With "Same as the page next to it", a blank page after a landscape page is landscape. Choose A4 or Letter for a fixed portrait size.
Are bookmarks and links kept?
Yes, the original pages are not changed. The inserted pages from another PDF keep their content, but that PDF's bookmarks are not added, and its form fields keep their look but are no longer fillable.
Is my PDF uploaded?
No. Pages are inserted by your browser and the result is saved on your device.
