WebP Joomla Image Optimization and Conversion is a game-changer for website owners who want to improve page load times and reduce image file sizes.
Joomla has a built-in feature that allows you to convert images to WebP format, which can be up to 30% smaller in size than traditional image formats.
This feature is available in Joomla 4 and later versions, making it easier for users to optimize their images without installing additional extensions.
By converting images to WebP, you can significantly reduce the file size and improve the overall performance of your website, which is especially important for mobile users who often have slower internet connections.

Advanced Directory Management
Advanced directory management is a crucial aspect of Joomla image optimization. With the ability to store optimized images in dedicated folders, you can keep your site organized and efficient.
Custom WebP output directories allow you to store optimized images in folders like "webp_thumbs" or "thumbnails". This keeps your site's image files separate from the original files.
A flat structure for large archives is perfect for news sites, where you can store all WebP files in a single directory regardless of their original location. This simplifies your site's directory structure.
A hashed filename system uses MD5-based unique filenames to prevent conflicts in multi-author environments. This ensures that each file has a distinct name.
Automatic directory creation creates required directories with proper permissions automatically, saving you time and effort.

File size filtering is another useful feature, which skips tiny icons or huge files that may cause timeouts. This helps to prevent unnecessary processing and ensures a smooth experience.

WebP Format in Joomla
You can use WebP images on your Joomla website, but there's a catch. Joomla's WebP support could be better, but you can use WebP images already.
To load them into the media manager, allow the .webp format in the Legal Extensions, Legal Image Extensions, and Legal MIME Types options. Unfortunately, Joomla! cannot generate a preview image for WebP images in the media manager.
To ensure visitors see the image, it's recommended to give an alternative using the HTML picture element. This means preparing images in two formats, which is a bit of a hassle. However, there are WebP plugins for Joomla that can make your life easier.
Here are some key settings to consider when using WebP images on your Joomla website:
- Select directories/folders to be processed and exclude particular directories or files from processing.
- Select image formats to be processed (choose .png, .jpg, or both formats).
- Set the quality of processed images (lower quality - smaller file size).

How to Enable File Format in Joomla
Enabling the WebP file format in Joomla is a bit of a process, but it's doable. You'll need to add the mime type to the Media global options.

To do this, go to the media global configuration (System -> Global Configuration -> Media). There, you'll need to add webp,WEBP to the list of global extensions (file types), add webp as a legal image extension, and add image/webp as a legal MIME types.
You can now upload and see WebP files in the media manager, but you won't have any preview for the file. It's a good idea to add a corresponding fallback image (either a JPG or a PNG image) into the media manager.
Here's a quick rundown of the steps:
Keep in mind that you won't be able to select an image with the WebP extension when using Joomla 3. You'll need to select the JPG or PNG version of the file and then edit the extension manually in the 'Image URL' field.

Joomla Image Support
Joomla's WebP support could be better, but you can use WebP images already. To load them into the media manager, allow this format in the options: Legal Extensions, Legal Image Extensions and Legal MIME Types.
Unfortunately, Joomla! cannot generate a preview image for WebP images in the media manager. This means that a visitor will not see the image if the browser has no WebP support. Therefore, it is recommended to give an alternative.
You can use the HTML picture element to provide a fallback image, which is usually a PNG image when transparency is required. The picture element tells browsers that do not support the WebP format that they can use the PNG provided as fallback.

Here's a quick rundown of the steps to enable WebP file format in Joomla:
- Add webp,WEBP to the list of global extensions (file types)

This will allow you to upload and see WebP files in the media manager, but you won’t have any preview for the file.
Flexible File Management
You can customize the filename suffix for WebP files, giving you more control over how they're named. By default, it's _iwebp, but you can change it to suit your needs.
The plugin also preserves the original file dates, which is useful if you need to maintain backup compatibility.
You can set minimum and maximum file sizes for processing, so you can control the output size of your WebP files.
The plugin allows you to choose between maintaining the original directory structure or organizing the files in a flat structure. This is especially useful for large archives or news sites.
Here's a breakdown of the flexible file management options:
Joomla Images
Joomla does not natively support the WebP image file format, but you can enable uploads through the Media manager by adding the mime type to the Media global options.
To allow WebP uploads, go to the media global configuration and add "webp,WEBP" to the list of global extensions, "webp" as a legal image extension, and "image/webp" as a legal MIME type.
When introducing a WebP image into the content, always add a corresponding fallback image, either a JPG or a PNG image, into the media manager.
You can use online tools like Zamzar to convert your images to WebP, or use local applications like GIMP, IrfanView, or Photoshop that support the WebP format.
