How to Insert a Blank Page in a PDF (Free Methods 2026)

You need to add a blank page to a PDF. Maybe you are preparing a duplex-printed document and need odd-page chapters to start on the right side. Maybe you want space for handwritten notes. Or you need separator pages between sections. Whatever the reason, inserting blank pages into a PDF is easier than you might think.

Common Reasons to Insert Blank Pages

• Duplex printing alignment: Ensure chapters start on a right-hand (odd-numbered) page when printing double-sided.
• Note pages: Add space for handwritten notes alongside printed content.
• Section separators: Visually divide sections in a long document.
• Form continuation: Add extra pages for long-form responses.
• Binding margins: Insert blank pages to balance page counts for booklet printing.

Method 1: Online PDF Page Inserter (Fastest)

1. Go to an online PDF editor like PDF24 Tools, Sejda, or iLovePDF.
2. Upload your PDF file.
3. Use the page management tool to add blank pages.
4. Choose the position where you want to insert the blank page.
5. Download your updated PDF.

Most online tools let you add a blank page at any position and even choose the page size to match your existing document.

Method 2: Using Adobe Acrobat

1. Open your PDF in Adobe Acrobat Pro.
2. Go to Tools > Organize Pages.
3. Click the Insert button in the toolbar.
4. Choose Blank Page from the dropdown.
5. Select the page size, orientation, and how many blank pages to insert.
6. Choose the position (before or after a specific page).
7. Click OK to insert.

Method 3: Using Mac Preview

Preview does not have a direct insert blank page button, but there is a reliable workaround:

1. Create a blank PDF page. Open TextEdit, create a blank document, and print to PDF.
2. Open your main PDF in Preview.
3. Open the blank PDF in a second Preview window.
4. Show thumbnails in both windows (View > Thumbnails).
5. Drag the blank page thumbnail from the second window into the thumbnail sidebar of your main document at the desired position.
6. Save the main document.

Method 4: Using Python (Automated)

For batch operations, use PyMuPDF:

import fitz
doc = fitz.open("document.pdf")
# Insert blank page after page 3 (0-indexed, so after index 2)
blank_page = doc.new_page(pno=3, width=612, height=792)  # US Letter
doc.save("output.pdf")

Dimensions are in points (72 points per inch). Common sizes:

• US Letter: 612 x 792 points (8.5 x 11 inches)
• A4: 595 x 842 points (210 x 297 mm)
• Legal: 612 x 1008 points (8.5 x 14 inches)

Inserting Multiple Blank Pages at Once

Need a blank page after every existing page for note-taking? Here is a Python script:

import fitz
doc = fitz.open("input.pdf")
total = len(doc)
for i in range(total - 1, -1, -1):
    page = doc[i]
    rect = page.rect
    doc.new_page(pno=i + 1, width=rect.width, height=rect.height)
doc.save("output.pdf")

Frequently Asked Questions

Will inserting a blank page change the existing page numbers?

The physical page count will increase, but page numbers embedded in the text will not automatically update. You may need to update them after inserting.

Can I insert a blank page of a different size?

Yes. PDFs can contain pages of different sizes. Most PDF editors let you choose the dimensions of the blank page independently.

Will bookmarks and links still work?

In most tools, bookmarks and internal links that point to specific pages will be automatically adjusted when you insert a new page. But always double-check after structural changes.
