To implement WebP image format support in WordPress, follow these steps:
- Update your WordPress version: Ensure that you are using the latest version of WordPress.
- Check WebP support: Confirm if your hosting server supports WebP image format. You can do this by creating a simple PHP file with the following code and running it on your server:
1 2 3 4 5 6 7 |
<?php if (imagewebp(1, 'test.webp')) { echo 'WebP is supported.'; } else { echo 'WebP is not supported.'; } ?> |
If the output displays "WebP is supported," move on to the next step. Otherwise, contact your hosting provider to enable WebP support.
- Install a WebP plugin: Install and activate a plugin that adds WebP support to your WordPress site. Some popular options include "WebP Express" and "Cache Enabler." You can find and install these plugins from the WordPress Plugin Directory.
- Configure the plugin: Once the plugin is activated, you may need to adjust some settings. Typically, you can find the plugin settings by going to "Settings" -> "WebP" in your WordPress dashboard. Configure the options according to your preferences. Some settings might include enabling WebP conversion, selecting the quality of converted images, and excluding certain images or directories from conversion.
- Test WebP support: After configuration, you should test if WebP support is working correctly on your site. Open an image attachment page or any page that contains images. Right-click on an image and select "Inspect" or "Inspect element" (this may vary depending on your browser). In the HTML code, look for the image source. If the image source URL ends with ".webp," it means WebP format is being used.
With these steps, you should now have WebP image format support implemented in your WordPress website.

What happens if a user uploads a non-WebP image in WordPress with WebP support enabled?
If a user uploads a non-WebP image in WordPress with WebP support enabled, the image will undergo conversion through WordPress plugins or server-side configuration, depending on how WebP support is implemented.
In such cases, the system will typically detect the uploaded image as a non-WebP format (e.g., JPEG, PNG, GIF) and automatically convert it to WebP format. The converted WebP image will then replace the original image, ensuring that it is served in WebP format to browsers that support it.
The process of conversion to WebP format may vary based on the WebP support implementation. Some WordPress plugins or server configurations may convert the image immediately upon upload, while others may generate the WebP version on-the-fly when a user requests it. Nonetheless, the end result will be that the image is available in WebP format to improve website performance without affecting image quality.
How to optimize WebP images for retina displays in WordPress?
To optimize WebP images for retina displays in WordPress, you can follow these steps:
- Install a WebP plugin: First, you need to install and activate a WebP conversion plugin on your WordPress site. Some popular options include "Optimus" and "EWWW Image Optimizer."
- Enable WebP conversion: The plugin will have settings to enable WebP conversion. Enable this feature so that the plugin converts your images to the WebP format for supported browsers.
- Generate WebP images: Once WebP conversion is enabled, the plugin will automatically generate WebP versions of your images in addition to the original format (e.g., JPEG or PNG). This will ensure that both WebP and non-WebP supporting browsers can view the image properly.
- Retina optimization: To optimize the WebP images for retina displays, you can modify your website's CSS to include the high-resolution image URLs for retina displays. You can use the following CSS code:
1 2 3 4 5 6 |
@media only screen and (-webkit-min-device-pixel-ratio: 2), only screen and (min-resolution: 192dpi) { .your-image-class { background-image: url('path-to-your-retina-image.webp'); } } |
Replace .your-image-class with the class or ID of the image element you want to optimize, and path-to-your-retina-image.webp with the URL of the high-resolution WebP image.
- Test and verify: After implementing the above steps, make sure to test your website on different devices and browsers, including retina displays, to ensure the WebP images are loading properly and optimized for retina screens.
Remember to always backup your WordPress site and images before making any changes, and regularly monitor your website's performance to ensure everything is running smoothly.
How to test if WebP images are properly loading in my WordPress website?
To test if WebP images are properly loading on your WordPress website, you can follow these steps:
- Install and activate the "WebP Express" plugin on your WordPress website. This plugin enables your site to serve WebP images to browsers that support the format.
- Once installed, go to the plugin's settings page. You can find this under "Settings" > "WebP Express" in your WordPress dashboard.
- In the "Basic" tab, make sure the "Do not use WebP express to serve WebP images" checkbox is unchecked. This ensures that the plugin is active and will generate the WebP versions of your images.

How to display a fallback image for unsupported browsers in WordPress?
To display a fallback image for unsupported browsers in WordPress, you can use the following steps:
- First, locate the theme folder in your WordPress installation. It is usually located in the wp-content/themes directory.
- Within the theme folder, locate the header.php file. This file controls the header section of your theme.
- Open the header.php file in a code editor, and find the tag that displays the main header image.
- Add an onerror attribute to the tag with a JavaScript function that replaces the image source with a fallback image. For example, you can use the following code:
1
|
<img src="main-header-image.jpg" onerror="this.src='fallback-image.jpg';" alt="Main Header Image">
|
In this code, if the main header image fails to load (due to an unsupported browser), the onerror attribute triggers and replaces the src attribute with the fallback image fallback-image.jpg.
- Save the header.php file and check your website in an unsupported browser or by disabling certain features to see if the fallback image is displayed when the main header image fails to load.
By following these steps, you can ensure that a fallback image is displayed for unsupported browsers in WordPress.
What is the impact of WebP image format on SEO in WordPress?
The WebP image format can have a positive impact on SEO in WordPress due to the following reasons:
