Frequently Asked Questions (FAQ)

PHP-Imagick to compress JPEG/PNG files (required). PHP-GD for WebP files (optional, but usually installed). In order to modify/resize/crop photos or images in WordPress, at least PHP-GD to extension is required. WordPress supports image editing and resizing only with two above listed extensions. When both extensions are installed, WordPress prefers PHP-Imagick over PHP-GD.
WordPress 5.2 and above: Administrator: Menu -> Tools -> Site Health -> Info -> Expand “Media Handling” and check if “ImageMagick version string” and “GD version” have values. WordPress 5.1 and below: Install Health Check & Troubleshooting plugin. Open “Health Check” plugin page and click on “PHP Information” tab. You will find there all PHP extensions installed and enabled. Search (Ctrl-F) on page for “Imagick” and “GD”. WordPress Editor class must be WP_Image_Editor_Imagick (or Warp_Image_Editor_Imagick) but NOT WP_Image_Editor_GD. PHP-Imagick extension must be linked with ImageMagick library version 6.3.2 or newer. PHP-GD extension version must be at least 2.0.0 to be accepted by WordPress Image Editor.
WPEngine: Both by default. EasyWP: Both by default. DreamHost: By configuration. SiteGround: Must enable. Ask your host-service provider.
PHP-Imagick setup CPanel based host Debian/Ubuntu: “apt-get install php-imagick”. Fedora/CentOs: “yum install php-imagick”. Ask your host-service provider.
See plugin HELP for instructions how to configure server to redirect .jpg/.png to .jpg.webp/.png.webp, if such file exists and browser suports webp image format.
To prevent overwriting duplicate “WebP” files. With single extension, when you upload “image.png” and “image.jpg”, second “image.webp” would overwrite previous one.
Because your server has no PHP-GD graphic editing extension or PHP-GD extension has no WebP support.
If WebP was never enabled, existing images remain optimized. New media thumbnails won’t be optimized. If you run “Regenerate Thumbnails” batch process, it will restore original file-size and quality of WordPress thumbnails. If you have WebP images, they won’t be deleted. You should delete all WebP images before deactivate/delete this plugin. To delete WebP images, disable Webp and batch-run “Regenerate Thumbnails” for all media images.
Because your server has not PHP-Imagick installed or has too old version of PHP-Imagick. Maybe some other plugin creates conflict.
