Click the Home tab at the top of Word. Right-click the paragraph marker ¶ that has the corresponding black bullet point. Select Paragraph… on the menu. Click the Lines and Page Breaks tab. Remove the check next to “Page break before” (if there is one) and click OK.
Also check the page right before your blank one for extra page breaks and delete those as well. Don’t select paragraph markers that appear on lines that contain actual content.
If the blank page is still there, double-check the pages before for page breaks.
The undeletable hidden paragraph usually occurs when the content of your last real page (not the blank page) goes all the way to the bottom of that page.
If there’s only one paragraph marker at the top of the page, deleting it won’t help—continue with this method, if so.
Click the Home tab if you’re not already there. Highlight the paragraph marker. Click the font size next to the font’s name. Replace it with 01 and press Enter or Return.
If you still have a blank page after this, you can reduce the size of the bottom margin instead. To do this, click the Layout tab, select Margins, click Custom Margins, and change the bottom margin to 0. 3 inches.
This only works on the desktop version of Word—the web version doesn’t let you choose which pages to include in a PDF. If your file is synced to One Drive, you won’t see Save as. Click Save as copy instead. If the document must be in the Word format, you can convert the PDF back to the Word format after you save it as a PDF.
