Using SVG in WordPress (2 Helpful Plugin Recommendations)

WordPress does not support SVG uploads by default because SVG files have powerful features, including the ability to load other resources and run JavaScript, which can lead to security vulnerabilities such as XSS attacks. However, if you need to use SVG images in WordPress (uploaded via media uploader and used in article content and featured images), you can do the following:

Using SVG directly in theme templates is feasible, whether inlined<svg></svg> No additional settings are required for the code or linking external SVG files through CSS.

Manually configure SVG support

WordPress blocks SVG uploads because the media library uploader rejects the MIME type of the SVG file. To allow SVG uploads, you need to add the following code to your functions.php file or feature plugin:

 function cc_mime_types($mimes) {
  $mimes['svg'] = 'image/svg xml';
  return $mimes;
}
add_filter('upload_mimes', 'cc_mime_types');

However, even with the above code added, the SVG file may still not be displayed correctly in the media library preview, featured image widgets, and editors. While this can be solved by injecting CSS code, this does not always work.

Support SVG with WordPress plugin

Given that WordPress itself does not support SVG, using plugins to manage SVG support is a better option. Plug-ins can be updated continuously as WordPress develops and solves possible compatibility issues.

The following two WordPress SVG plugins are recommended:

SVG Support

This is a powerful plug-in that can be used after installation and activation, without additional configuration. It provides some setting options such as whether to load additional front-end CSS (recommended to choose as needed). The plugin also provides administrator privilege restrictions for enhanced security.

Safe SVG

Although this plugin is slower to update, it provides a higher level of security and cleans and optimizes SVG files when uploading. If you have high requirements for website security or lack technical experience, this plugin is more suitable for you.

Other plug-ins, such as Easy SVG Support, are not recommended here due to insufficient maintenance and updates.
