# Insert Blank Pages into a PDF

> Add blank pages at chosen positions — for double-sided printing, notes or separators.

To insert blank pages into a PDF, choose where they go — after specific pages, before them, at the end, or after every page for double-sided printing. Blank pages match the size of their neighbour by default, so a mixed-size document stays consistent.

## How to add a blank page to a PDF

1. Drop the PDF in. It is read and rewritten in a worker thread on your own machine, so the file never leaves the browser.
2. Choose where the blanks go: after the pages you list, before them, at the end, or after every page.
3. Type the positions. `4` inserts at one place, `1, 4, 9` at three, and a range such as `2-5` inserts after each page in the run.
4. Set how many blank pages each position gets, if one is not enough.
5. Leave the size on **match the neighbouring page** unless you specifically need A4 or Letter.
6. Download the rebuilt file. The meta line tells you the old and new page counts so you can check the arithmetic.

## Which option you want

| Option | What it is for |
| --- | --- |
| After the listed pages | A separator before a new section, or space left for an appendix. |
| Before the listed pages | Slipping a cover or divider in ahead of an existing page. |
| At the end | Padding a document out to a whole number of sheets before a print run. |
| After every page | Duplex printing where each sheet is used on one side only, and workbooks meant to be written on. |

The last one is also how you force every chapter to open on a right-hand page in a bound document. Add a blank after each odd-length section and the recto/verso alignment holds for the rest of the book.

## Why the blank page matches its neighbour

A PDF can mix page sizes freely, and plenty do: a Letter report with one A3 foldout, or a scanned bundle where every page came off a different device. Inserting a fixed A4 blank into that means the printer either switches tray or scales the sheet, and you find out at the printer rather than on screen. Matching the neighbour keeps the inserted page invisible in the page setup. If the document really should be uniform, [resize the pages](https://convertto.tech/t/resize-pdf-pages) first and then insert.

> **What a rewrite does not carry** — Inserting pages rebuilds the document from its pages. Page content, sizes and rotation come across intact, but document-level structure such as the bookmark outline and interactive form wiring may not survive a rewrite in any tool that works this way. Keep the original if you depend on those, and check the result before you discard it.

For the opposite jobs, [delete pages](https://convertto.tech/t/delete-pdf-pages) removes them, [the page organiser](https://convertto.tech/t/pdf-page-organiser) reorders and rotates, and [merge PDF](https://convertto.tech/t/merge-pdf) joins whole files.

## How to use

1. Select your pdf file — the file stays on your device and is never uploaded.
2. Choose the insert.
3. Enter or paste your pages.
4. Set the blank pages each time.
5. Choose the blank page size.
6. Press Run, then download the result when it is ready.

## FAQ

### Why would I add a blank page after every page?

For double-sided printing where you want each sheet printed on one side only — a workbook where readers write on the back, or a document that will be annotated. It is also how you force a chapter to start on a right-hand page in a bound document.
