Resolve the Issue of Blank Pages When Using html2pdf Library

Have you ever tried to generate a PDF only to see a frustrating blank page? If you’re using the html2pdf library for your JavaScript project and encountering blank pages in your generated PDF, you’re not alone. This common issue can stem from various reasons, but fortunately, there are straightforward solutions to get your PDFs looking just the way you want.

Understanding the Problem

When utilizing the html2pdf library, many developers report generating files that appear blank. This can happen for several reasons, including:

Mistakes in the HTML structure or content.

Incorrect parameters set in the code.

Timing issues with rendering the content.

Let’s dive into how to resolve this problem effectively.

Solutions to Generate a Non-Blank PDF

1. Using the outputPdf('blob') Method

One effective solution is to use the outputPdf('blob') method. This method handles the PDF output in a way that can help eliminate issues with blank pages.
