What size are the blank pages?

The inserted blank pages match the page size of the document they're being inserted into. If your document uses A4, the blank pages are A4. If it's Letter, they're Letter. This ensures consistent printing and avoids any alignment issues. The blank pages have the same dimensions and orientation (portrait or landscape) as the surrounding pages.

Can I insert a blank page at the very beginning of the document?

Absolutely — just specify 'insert a blank page before page 1' or 'add a blank page at the front.' This is commonly used to create a title page or cover sheet that you can fill in later, or to add a blank page for note-taking before the document content begins.

Do blank pages have any margins, headers, or hidden content?

No — the blank pages are completely empty. No default margins, no hidden text, no watermarks, no page numbers. They're truly blank canvases. If you want to add page numbers or headers to the blank pages later, you can use the add_page_numbers or add_header_footer tools separately.

Can I insert blank pages in a PDF that already has form fields or annotations?

Yes — inserting blank pages doesn't affect the existing content or fields on other pages. The blank pages are new pages with no fields, annotations, or content. If you need to add fields to the blank pages later, you'd use a separate form creation tool.

What's the use case for inserting blank pages in a PDF?

The most common use cases are: adding divider pages between sections of a long report (often with a section title printed later), creating space for signatures or stamps after the content, ensuring that content starts on a right-hand page for double-sided booklets, adding pages for handwritten notes in a printed document, or simply creating room for future edits or additions. It's a simple but essential operation for document preparation.

Insert Blank Pages into a PDF Online — Free, No Sign-Up, No Watermarks

Sometimes you just need empty space. A blank divider page between sections of a report, a blank page at the end for handwritten notes, or a blank page inserted for double-sided printing where you need content to start on the right-hand page. FlowPDF lets you insert one or more blank pages anywhere in your document — before page 1, between pages, or at the end. Each blank page is a clean, white canvas with no headers, footers, or watermarks — truly empty. This is the simplest PDF operation you'll ever do, but it's surprisingly hard to find in free online tools. Most PDF editors force you to create a blank document separately and then merge it, or they insert a blank page but with default margins that mess up your layout. FlowPDF inserts exactly what you need: a completely empty page in the exact position you specify, with the correct page dimensions matching the rest of your document.

Frequently asked questions
