Speed up your website using our ease image optimizer by serving WebP and AVIF images. By replacing files in standard JPEG, PNG and GIF formats with WebP and AVIF formats, you can save over a half of the page weight without losing quality.
After installing the plugin you do not have to do anything more. Your current images will be converted into a new format. When image optimization by our image optimizer is finished, users will automatically receive new, much lighter images than the original ones.
As of today, over 90% of users use browsers that support the WebP format. The loading time of your website depends to a large extent on its weight and the level of image optimization. Using our WebP Converter, now you can and speed up it in a few seconds without much effort!
This will be a profit both for your users who will not have to download so much data, but also for a server that will be less loaded. Remember that a better optimized website also affects your Google ranking. Image optimization is very important.
AVIF support
Now in the PRO version you can use AVIF as the output format for your images. The AVIF format is a new extension – is the successor to WebP. AVIF allows you to achieve even higher levels of image compression, and the quality of the converted images after image optimization is better than in WebP.
How does this work?
- If you have just installed the plugin, you can optimize images with one click. Image size will be smaller after generate webp!
- New images that will be added to the Media Library will be converted automatically.
- Our image optimizer does not modify your original images in any way. This means security for you and your files.
- When the browser loads an image, our plugin checks if it supports the WebP format. If so, the image in WebP format is loaded.
- The plugin does not make redirects in default mode, so the URL is always the same. Only the MIME type of the image changes to
image/webp
. - No redirects means no cache issues, faster and trouble-free operation of your website. If you want to know more about how it works, check out the plugin FAQ below.
- It does not matter if the image display as an
img
HTML tag or you usebackground-image
. It works always! - In case rewriting by rules from .htaccess file is blocked, a mode is available which loads images via PHP file. Then image URLs are changed, but the logic of operation is the same as in the case of the default mode.
- The final result after image optimization is that your users download less than half of the data, and the website itself loads faster!
- You lose nothing – if you had to remove the plugin, it will remove everything after itself. It does not leave any trace, so you can check it with ease.
Convert WebP – it is the future of image optimization!
Optimize images and raise your website to a new level now! Install the plugin and enjoy the website that loads faster by image optimization. Surely you and your users will appreciate it.
Support for additional directories

directory but also from /plugins
and /themes
directories. This allows full integration with the WebP format!

-
Error while converting?
-
You can get several types of errors when converting. First of all, carefully read their content. For the most part, you can solve this problem yourself. Try to do this or contact the server administrator.
If you get an error:
File "%s" does not exist. Please check file path.
means that the file_exists() function in PHP returnedfalse
using the file path given in the error message. Check this path and make sure it is correct.If you get an error:
File "%s" is unreadable. Please check file permissions.
means that the is_readable() function in PHP returnedfalse
using the file path given in the error message. Check the permissions for the file and the directory in which the file is located.If you get an error:
"%s" is not a valid image file.
means that the file is damaged in some way. Download the file to disk, save it again using any graphics program and add it again to the page. If the error applies to individual images then you can ignore it – just the original images will load, not WebP.If you get an error:
Image "%s" converted to .webp is larger than original and converted .webp file has been deleted.
means the original image weighed less than WebP. This happens when images have been compressed before. Disable the “Automatic removal of files in output formats larger than original” option in plugin settings to force always using WebP. -
What are requirements of plugin?
-
Practically every hosting meets these requirements. You must use PHP at least 7.0 and have the
GD
orImagick
extension installed. The extension must supportWebP format
. If you have an error saying that the GD or Imagick library is not installed, but you have it installed then they are probably incorrectly configured and do not have WebP support.They are required native PHP extensions, used among others by WordPress to generate thumbnails. Your server must also have the modules
mod_mime
,mod_rewrite
andmod_expires
enabled.An example of the correct server configuration can be found here. The link to your current configuration can be found in the Help Center tab on plugin settings screen.
Note the items marked in red. If the values marked in red do not appear in your case, it means that your server does not meet the technical requirements. Pay attention to the WebP Support value for the GD library and WEBP in the list of supported extensions for the Imagick library.
In a situation where your server does not meet the technical requirements, please contact your server Administrator. We are not able to help you. Please do not contact us about this matter, because this is a server configuration problem, not a plugin.
Also, REST API must be enabled and work without additional restrictions. If you have a problem with it, please contact the Developer who created your website. He should easily find the issue with the REST API not working.

How to check if the plugin works?
-
You can find more information on how the plugin works in our manual.
-
How to change the path to uploads?
-
This is possible using the following types of filters to change default paths. It is a solution for advanced users. If you are not, please skip this question.
Path to the root installation directory of WordPress (
ABSPATH
by default):add_filter( 'webpc_site_root', function( $path ) { return ABSPATH; } );
Paths to directories (relative to the root directory):
add_filter( 'webpc_dir_name', function( $path, $directory ) { switch ( $directory ) { case 'uploads': return 'wp-content/uploads'; case 'webp': return 'wp-content/uploads-webpc'; case 'plugins': return 'wp-content/plugins'; case 'themes': return 'wp-content/themes'; } return $path; }, 10, 2 );
Note that the
/uploads-webpc
directory must be at the same nesting level as the/uploads
,/plugins
and/themes
directories.Prefix in URL of
/wp-content/
directory or equivalent (used in .htaccess):add_filter( 'webpc_htaccess_rewrite_path', function( $prefix ) { return '/'; } );
For the following sample custom WordPress structure:
... ├── web ... ├── app │ ├── mu-plugins │ ├── plugins │ ├── themes │ └── uploads ├── wp-config.php ...
Use the following filters:
add_filter( 'webpc_site_root', function( $path ) { return 'C:/WAMP/www/project/web'; // your valid path to root } ); add_filter( 'webpc_htaccess_rewrite_path', function( $prefix ) { return '/'; } ); add_filter( 'webpc_dir_name', function( $path, $directory ) { switch ( $directory ) { case 'uploads': return 'app/uploads'; case 'webp': return 'app/uploads-webpc'; case 'plugins': return 'app/plugins'; case 'themes': return 'app/themes'; } return $path; }, 10, 2 );
After setting the filters go to
Settings -> Converter for Media
in the admin panel and click theSave Changes
button..htaccess
files with appropriate rules should be created in the directories/uploads
and/uploads-webpc
. -
How to exclude paths from converting?
-
To exclude selected directories, provide them in the
Excluded directories
field in the Advanced Settings tab in the plugin settings.In this field, you can enter a directory name or path. Here are examples:
–2023
–2024/01
–2023,2024/01
To exclude selected files, use the following filter (in this case with the suffix “-skipped” in a filename, e.g. image-skipped.png):
add_filter( 'webpc_supported_source_file', function( bool $status, string $file_name, string $server_path ): bool { $excluded_suffix = '-skipped'; if ( strpos( $file_name, $excluded_suffix . '.' ) !== false ) { return false; } return $status; }, 10, 3 );
Argument
$server_path
is the absolute server path to a directory or file. Inside the filters, you can apply more complicated rules as needed.Changes to excluded directories and files take effect before images are converted – they do not affect already converted images. These images must be manually removed from the directory:
/wp-content/uploads-webpc/
. -
Support for custom directories
-
The plugin supports the following directories by default:
–/gallery
–/plugins
–/themes
–/uploads
If you want to add support for a custom directory, add the following code to the functions.php file in your theme directory (use a correct directory name instead of
custom-directory
):add_filter( 'webpc_source_directories', function ( $directories ) { $directories[] = 'custom-directory'; return $directories; } );
Remember that this directory must be located in the
/wp-content
directory. -
How to run manually conversion?
-
By default, all images are converted when you click on the
Start Bulk Optimization
button. In addition, conversion is automatic when you add new files to your Media Library.Remember that our plugin takes into account images generated by WordPress. There are many plugins that generate, for example, images of a different size or in a different version.
If you would like to integrate with your plugin, which generates images by yourself, you can do it. Our plugin provides the possibility of this type of integration. This works for all images in the
/wp-content
directory.It is a solution for advanced users. If you would like to integrate with another plugin, it’s best to contact the author of that plugin and give him information about the actions available in our plugin. This will help you find a solution faster.
You can manually run converting selected files, you can use the action to which you will pass an array with a list of paths (they must be absolute server paths):
do_action( 'webpc_convert_paths', $paths, true );
An alternative method is to manually start converting the selected attachment by passing the post ID from the Media Library. Remember to run this action after registering all image sizes (i.e. after running the
add_image_size
function):do_action( 'webpc_convert_attachment', $post_id, true );
To delete manually converted files, use the following action, providing as an argument an array of absolute server paths to the files (this will delete manually converted files):
do_action( 'webpc_delete_paths', $paths );
-
Support for WP-CLI
-
The plugin supports WP-CLI, which enables faster image conversion from the server level. More information on how to get started with WP-CLI can be found in the Handbook. The supported commands are described below.
Checking how many maximum images for conversion are on website:
wp converter-for-media calculate
Converting all images:
wp converter-for-media regenerate
Converting all images (with “Force convert all images again” option):
wp converter-for-media regenerate --force
-
Does plugin support CDN?
-
The website files (WordPress files) and the images from the Media Library must be on the same server. If they are, everything should work fine.
If only your images are on another CDN server, unfortunately correct operation is impossible, because such images are managed by another server.
Current list of supported CDN servers:
– BunnyCDN (refer to the instructions before use)
