JavaScript in HTML To PDF

IronPDF allows users to directly embed images into PDFs by allowing them to embed images directly into HTML strings rather than loaded as external assets.

Some of these assets could include

Image Files
System.Drawing.Image
System.Drawing.Bitmap

This is useful because it helps avoid loading external assets during HTML to PDF rendering. It can improve speed and cut down on loading times. It also allows the entire render file to be stored in non-file-system locations such as strings or databases

In this example, we will show you how you can directly embed images into your PDFs.

Some of the best practices when working with HTML strings and documents is not to depend on a directory of assets. We can use DataURIs to directly inject images, files, and even typefaces into an HTML document as a string. It is a very useful method for working with files and images in your PDF.
