Do you want to add SVG files to your WordPress site? By default, WordPress allows you to upload all popular image, audio, and video file formats, but SVG is not among them. In this article, we will show you how to easily add SVG in WordPress.
What is SVG?
SVG or Scalable Vector Graphics is a file format that defines vector-graphics using the XML markup language. The main benefit of SVG is that it allows you to enlarge images without losing quality or having any pixelation.
How does SVG work?
Scalable Vector Graphics (SVG) is a technology that displays two-dimensional drawings using XML. They are different than the commonly used image formats like PNG, GIF, or JPEGs.
If you take a png / jpeg image file and zoom in, then you will notice that the image will start to blur and become pixelated.
Vector graphics don’t use pixels. Instead, they use a two-dimensional map that defines the graphic you are viewing. As you zoom in, the image doesn’t pixelate.
This enables you to enlarge vector graphics without losing quality. Most importanly, SVG images can be way smaller in filesize than JPEGs or PNG.
Vector graphics are commonly used for icons, icon fonts, website logos, and branding images. You may want to add SVG files in WordPress for your company logo, icons, or other graphics.
As cool as they sound, SVG files are still a bit unsafe. That’s why WordPress doesn’t support SVG file uploads by default.
If you upload an SVG image in WordPress, then you will see the following error message:
Sorry, this file type is not permitted for security reasons.
Security Issues Concerning SVG in WordPress
SVG files contain code in the XML markup language which is similar to HTML. Your browser or SVG editing software parses the XML markup language to display the output on the screen.
However, this opens up your website to possible XML vulnerabilities. It can be used to gain unauthorized access to user data, trigger brute force attacks, or cross-site scripting attacks.
The methods we will share in this article will try to sanitize SVG files to improve their security. However, these plugins cannot totally prevent malicious code from being uploaded or injected.
The best solution is to only use SVG files that are created by reliable sources and to restrict SVG uploads to trusted users only.
