Add Blank Pages to PDF
Insert blank pages into any PDF at custom positions or every N pages. Great for note-taking, duplex printing, booklets. Free and private. Free online.
How to use
Upload PDF — Drop in the document where you want blanks inserted.
Choose Where to Insert — After specific pages, before specific pages, or after every N pages.
Download Updated PDF — Blank pages match the source page size automatically.
The PDF Add Blank Pages tool inserts empty pages at chosen positions in any PDF — for duplex print alignment, note-taking handouts, chapter dividers, and booklet preparation.
Insertion modes
After specific pages — e.g. "3, 7" inserts blanks after pages 3 and 7.
Before specific pages — useful for "chapter starts on a right-hand page" booklets.
Every N pages — auto-insert a blank every 2nd, 3rd, or 5th page for note-taking room.
How it works
The tool copies your source pages into a new PDF and inserts blank pages with the source's first-page dimensions, ensuring consistent page sizes. Built on pdf-lib, all processing is local.
Privacy
No upload, no server, no tracking. Your PDF is processed entirely inside your browser.
Frequently asked questions
Why insert blank pages?
Common reasons include duplex (front/back) printing alignment, creating room for handwritten notes, separating chapters with clean breaks, or preparing booklets where odd-page chapters must start on a right-hand page.
Are blank pages the same size as the original?
Yes — the tool reads the size of the first page and creates blanks with identical dimensions, ensuring no awkward mixed page sizes.
What's the difference between 'after' and 'before' modes?
'After 3' inserts a blank between pages 3 and 4. 'Before 3' inserts a blank between pages 2 and 3. Use whichever matches how you mentally describe the position.
Can I add blanks every 2 pages for note-taking?
Yes — choose 'Every N pages' and set N to 2. The tool inserts a blank after every 2nd source page, perfect for lecture slide note-taking handouts.
