Once everything is working fine, I recommend cleaning the database of any trace of jpg, it helped me to remove a lot of jpg garbage.
]]>Hi there @katsushi-kawamori, hope you’re doing well. We’ve been installing your plugin on more of our sites and it’s been a great experience overall.
We did end up finding one bug on one of our WooCommerce sites in which the image thumbnails were appearing broken in the Media Library due to it trying to load them as image-100×100.png rather than image-100×100.webp.
Strangely, the bug was only happening on one of our WooCommerce sites but not the others. After some initial debugging, we first thought that it was due to a three-way plugin conflict with WooCommerce, your plugin, and a WooCommerce extension, but after digging deep into the issue, we found that it wasn’t directly related to WooCommerce or the other plugin but rather due to any two plugins defining the same image size.
Here’s an example of a snippet that will break the thumbnails when your plugin’s “Replace” setting is enabled:
add_action( 'init', 'webpdebug_add_image_sizes');
function webpdebug_add_image_sizes()
{
add_image_size( 'webpdebug_bugtest_size', 100, 100, 1 );
add_image_size( 'woocommerce_gallery_thumbnail', 100, 100, 1 );
}After doing a deep dive into your plugin’s code, we found that this code in /lib/class-pluswebp.php was the source of the issue:
foreach ( (array) $metadata['sizes'] as $key => $value )
{
$file_thumb = $value['file'];
$file_thumb_webp = $this->change_ext( $file_thumb, $ext, $pluswebp_settings['addext'] );
$ret = $this->create_webp( $path . $file_thumb, $mime_type, $path . $file_thumb_webp, $pluswebp_settings['quality'], $pluswebp_settings['output_mime'] );
if ( $ret || file_exists($path . $file_thumb_webp) )
{
$metadata_webp['sizes'][ $key ]['file'] = $file_thumb_webp;
$metadata_webp['sizes'][ $key ]['mime-type'] = $pluswebp_settings['output_mime'];
$webp_size = filesize( $path . wp_basename( $file_thumb_webp ) );
$metadata_webp['sizes'][ $key ]['filesize'] = $webp_size;
if ( $pluswebp_settings['replace'] )
{
wp_delete_file( $path . $file_thumb );
$this->change_db( $url . $file_thumb, $url . $file_thumb_webp );
}
}
}The code above has a bug where, if the WebP or AVIF image already exists, it won’t update the database value due to the create_webp call returning false.
We experimented with several different fixes and found that the most straightforward fix is just a simple fallback condition that checks to see if the image already exists:
if ( $ret || file_exists($path . $file_thumb_webp) ) Technically there are other possible ways to fix it like performing the file_exists check in the create_webp function and returning true instead of false, but either way should be fine.
]]>Hi there, we tried permanently converting all of our media library images to WebP with this plugin. It worked well for most images, but some of our PNG images had their transparent background converted to black pixels, so we had to do a rollback.
Here’s an example of one of the affected images: https://sitebolts.com/temp/icon3.png
And what it looks like after conversion: https://sitebolts.com/temp/icon3.webp
Other than that, the plugin worked great; most of our image sizes were reduced by half or more. Would it be possible to fix the transparency issue?
]]>Hello.
Looks like it doesn`t support your Image to text plugin.
]]>Hi Boss.. I have a solution for support Woo and some othet meta.. The problem lies in the imperfection of the function, which does not take into account some aspects DB replaceing..
This is happening because you are not updating additional meta fields and options. For example:

Report on the Modification of the change_db Function Purpose of the Changes
The primary goal of the changes was to correctly update all necessary entries in the WordPress database after converting images to the WebP format. This includes replacing old image URLs with new ones, especially for WooCommerce products. Issues with the Original Code
- Incomplete URL Updates: The original code did not update all necessary entries in the database. It only updated the
wp_poststable, resulting in some image URLs remaining unchanged, particularly for WooCommerce products. - Lack of Updates in
wp_postmetaandwp_optionsTables: The code did not account for updating image URLs in thewp_postmetaandwp_optionstables, where image references are also stored.
Changes Made
- Added Updates in
wp_postmetaandwp_optionsTables: Updates were added for thewp_postmetaandwp_optionstables to ensure correct image URL references across the database. - Improved the
change_dbFunction: The function was improved to perform URL replacements in three tables (wp_posts,wp_postmeta,wp_options), ensuring a more comprehensive and correct database update.
Original Code
private function change_db($before_url, $after_url) {
global $wpdb;
/* Replace */
$wpdb->query(
$wpdb->prepare(
"
UPDATE {$wpdb->prefix}posts
SET post_content = replace(post_content, %s, %s)
",
$before_url,
$after_url
)
);
}Updated Code
private function change_db(string $before_url, string $after_url): void {
global $wpdb;
try {
// Ensure URLs are valid strings
if (empty($before_url) || empty($after_url)) {
throw new Exception('URLs must not be empty.');
}
// Update wp_posts table
$posts_query = $wpdb->prepare(
"UPDATE {$wpdb->prefix}posts SET post_content = REPLACE(post_content, %s, %s)",
$before_url,
$after_url
);
$posts_result = $wpdb->query($posts_query);
if ($posts_result === false) {
throw new Exception('Failed to update wp_posts table.');
}
// Update wp_postmeta table
$postmeta_query = $wpdb->prepare(
"UPDATE {$wpdb->prefix}postmeta SET meta_value = REPLACE(meta_value, %s, %s)",
$before_url,
$after_url
);
$postmeta_result = $wpdb->query($postmeta_query);
if ($postmeta_result === false) {
throw new Exception('Failed to update wp_postmeta table.');
}
// Update wp_options table
// Use a safe method to update options that may contain serialized data
$options = $wpdb->get_col("SELECT option_name FROM {$wpdb->prefix}options WHERE option_value LIKE '%{$before_url}%'");
foreach ($options as $option_name) {
$option_value = get_option($option_name);
if (is_array($option_value)) {
foreach ($option_value as $key => $value) {
if (is_string($value) && strpos($value, $before_url) !== false) {
$option_value[$key] = str_replace($before_url, $after_url, $value);
}
}
update_option($option_name, $option_value);
} elseif (is_string($option_value) && strpos($option_value, $before_url) !== false) {
$updated_value = str_replace($before_url, $after_url, $option_value);
update_option($option_name, $updated_value);
}
}
// Log success message
error_log("Successfully replaced URLs in wp_posts, wp_postmeta, and wp_options tables: $before_url to $after_url");
} catch (Exception $e) {
// Log the error message
error_log('Error changing database content: ' . $e->getMessage());
}
}Using the Updated Function
The change_db function should be called after converting an image to the WebP format and saving it on the server. The function takes two parameters: the URL of the image before and after the format change. This will ensure that all database records referencing this image are correctly updated.
// Example of calling the change_db function
/* Replace */
$this->change_db( $this->upload_url . '/' . $metadata['file'], $this->upload_url . '/' . $file_webp );This update ensures the correct replacement of all image URLs in the WordPress database, maintaining the stability and accuracy of your site’s functionality.
]]>Unable to convert webp when connecting to third-party image repositories (such as Cloudflare R2 and Amazon S3)
]]>Hello,
try convert: jpg, png only
I attempted to convert all the images in my blog and shop, which is about 500 images. I started the process, and it stopped at 20% without any error. When I tried to run it again, I received the following error: PHP Fatal error: Palette image not supported by webp in X:\xampp\htdocs\wp-includes\class-wp-image-editor.php on line 592. I attempted to fix it myself by adding the following rules to handle the imagecreatetruecolor function in public function get_allimages() and enhancing the create_webp function:
private function create_webp( $filename, $mime_type, $filename_webp ) {
if ( ! file_exists( $filename ) ) {
return false;
}
if ( file_exists( $filename_webp ) ) {
return false;
}
$pluswebp_settings = get_option( 'pluswebp' );
@set_time_limit( 60 );
wp_raise_memory_limit( 'pluswebp' );
$ret = false;
switch ( $mime_type ) {
case 'image/jpeg':
$src = imagecreatefromjpeg( $filename );
$img = imagecreatetruecolor( imagesx( $src ), imagesy( $src ) );
imagealphablending( $img, true );
break;
case 'image/png':
$src = imagecreatefrompng( $filename );
$img = imagecreatetruecolor( imagesx( $src ), imagesy( $src ) );
imagealphablending( $img, false );
imagesavealpha( $img, true );
break;
case 'image/gif':
// Check if GIF has a palette
$image_data = getimagesize( $filename );
if ( isset( $image_data['channels'] ) && $image_data['channels'] > 3 ) {
// Log the file that couldn't be converted due to palette
$this->log_unsupported_webp_file( $filename );
return false;
}
$src = imagecreatefromgif( $filename );
$img = imagecreatetruecolor( imagesx( $src ), imagesy( $src ) );
imagealphablending( $img, true );
break;
default:
// Log unsupported mime types
$this->log_unsupported_webp_file( $filename );
return false;
}
imagecopy( $img, $src, 0, 0, 0, 0, imagesx( $src ), imagesy( $src ) );
imagedestroy( $src );
$ret = imagewebp( $img, $filename_webp, $pluswebp_settings['quality'] );
imagedestroy( $img );
return $ret;
}
// Function to log unsupported WebP files using WooCommerce Logger
private function log_unsupported_webp_file( $filename ) {
if ( class_exists( 'WC_Logger' ) ) {
WC_Logger::instance()->debug( 'Unsupported WebP file: ' . $filename );
}
}Additionally, I added various logs to understand the root cause of the conversion issue. The “Palette” error has disappeared, but the process reaches 100% and reports as completed. However, after refreshing the page, it shows “Found 284 media that can be generated.” This might be caused by various reasons. It also seems that the library does not delete the original files, although I have enabled the option.
Could you provide some advice? Perhaps you have a debug version to determine why it stops converting images even though it reports 100% progress. I’ve tried making various adjustments to find the root cause of the issue, but since I’m not the developer, it’s difficult for me to figure out how it works.
Thank you.

Version 3.0.0
quality: 85
plus-webp has a feature that automatically converts images to webp format after users upload them.
WordPress has a function that can use ctrl+v to automatically upload the picture in the clipboard when editing an article, and add the picture URL in the article. Normally, the file name of the uploaded image is image. If there is already an image named image, the image name is image-1, image-2, and so on.
If these two functions work independently, they can do a good job. But when using both functions at the same time, the bug appears.
First I uploaded an image using ctrl+v, it was named image.jpg in the media library, plus-webp converted it to webp format, named it image.webp, and automatically deleted image.jpg, which was fine.
Then when I upload a second file using ctrl+v, WordPress still names it image.jpg since image.jpg has been deleted, and that’s the problem.
Now both image.jpg and image.webp exist, so plus-webp can’t do the conversion work because the file name image.webp is already taken.
But it seems that the function of automatic URL replacement is still in effect, so in the editor, the two pictures will be displayed as the first picture.
When I uploaded the third image, because image.jpg already existed, WordPress named it image-1.jpg, and now plus-webp can convert it to image-1.webp normally, so the first The three pictures can be displayed normally in the article.
In short, this bug causes users to use ctrl+v to upload pictures, and every second picture will have a bug because it cannot be converted.
I suggest that plus-webp check if the target file name exists before converting the file, for example, before converting image.jpg, check if image.webp already exists, and if it exists, try to convert it to image-1.webp, If image-1.webp also exists, it tries to convert it to image-2.webp, and so on. This approach should solve the above problems.
Since I don’t know PHP programming language, this is just my suggestion, please forgive me if I offend you.
Finally, thank you for the plugin, it’s really nice.
