Enabling SVG Support in WordPress

By default, WordPress restricts the use of SVG files for security reasons. However, several methods are available to enable SVG support, allowing you to harness the power of SVG images on your site.

What is SVG, and What are the Benefits?

Scalable Vector Graphics (SVG): SVG is an XML-based file format used to describe two-dimensional vector graphics. Unlike raster images like JPEG or PNG, which use a grid of pixels, SVG uses mathematical equations to define lines, shapes, and colors, ensuring that images remain crisp and clear at any resolution. This vector-based approach makes SVG ideal for responsive web design and high-resolution displays.

Benefits of Using SVG:

  1. Resolution Independence: SVG graphics are resolution-independent, meaning they can be scaled to any size without losing clarity. This adaptability ensures your graphics look sharp on any device, from small mobile screens to large desktop monitors.

  2. Small File Size: SVG files are generally smaller than raster image formats. This smaller file size improves website loading times and provides a faster and more enjoyable user experience.

  3. Retina Display Support: SVG images look exceptional on Retina displays and other high-density screens, maintaining their sharpness and quality even on devices with high pixel densities.

  4. Accessibility: SVG images are accessible to screen readers and assistive technologies, making them an inclusive choice for visually impaired users.

  5. Animations and Interactivity: SVG supports animations and interactivity through CSS and JavaScript, allowing you to create engaging and dynamic visual elements on your website.

  6. Scalability in Design: With SVG, you can design logos, icons, and illustrations that can be resized and reused across your website without needing multiple versions.

Method 1: Manual Code Modification

  • Create a Child Theme (Recommended): Creating a child theme is vital to safeguard your changes from being overwritten during theme updates. To do this, create a new folder in the "wp-content/themes/" directory, naming it something like "your-child-theme." Within the child theme folder, create a new file named "functions.php."

  • Add Code to Enable SVG Support: Open the "functions.php" file with a text editor and add the following code snippet:
function allow_svg_upload( $mimes ) {
    $mimes['svg'] = 'image/svg+xml';
    return $mimes;
add_filter( 'upload_mimes', 'allow_svg_upload' );

Save the changes to the "functions.php" file.

Method 2: Use the "SVG Support" Plugin

  1. Install and Activate the "SVG Support" Plugin: In your WordPress admin dashboard, go to "Plugins" > "Add New" in the sidebar menu. Search for the "SVG Support" plugin developed by "Benbodhi." Click "Install Now," followed by "Activate."

  2. Configure the "SVG Support" Plugin: After activating the plugin, head to 'Settings' --> 'SVG Support' in the sidebar menu. Review the plugin settings and make any necessary adjustments. By default, the plugin enables SVG support for uploads and media library display.

  3. Upload and Use SVG Files: To use SVG files, create or edit a post or page or you can directly upload the SVG files in the Media Library. Click the 'Add New' button to open the media uploader. You can drag your files or upload them one by one, and the files will be uploaded to your site. Once uploaded, insert the SVG file into your post or page like any other media file.

Whether you opt for manual code modifications or utilize the "SVG Support" plugin, you'll gain the ability to safely upload and display SVG files, elevating your site's visual elements and providing an exceptional user experience.
