Quick answer
To add a blank page to a PDF online for free, upload your PDF into the KaviForge Insert Blank Page tool, click the page thumbnail where you want the blank page, choose "Before current page", "After current page", "At start", or "At end", set the number of blank pages, click "Add blank", and download your PDF.
Whether you need extra space for handwritten lecture notes, a clean cover sheet, or a spacer page so chapters start on the right-hand side when printing double-sided, inserting a blank page into an existing PDF shouldn’t require paid desktop software.
This tool automatically matches the exact page dimensions (A4, US Letter, Legal, or custom slide size) of your PDF and inserts clean white pages at the exact position you choose—locally in your browser.

How Blank Page Insertion Works
When you click "Add blank", the tool reads the media box dimensions (`width` and `height` in PDF points) of your currently selected page and inserts new empty page objects into the PDF structure using `pdf-lib`.
Because no server upload takes place, even large 200-page PDF textbooks or confidential business documents process in seconds.
