Imagick is enabled in the PHP environment that runs your WordPress site—not with a WordPress dashboard switch. If you use managed hosting, enable the Imagick PHP extension for the site’s assigned PHP version in your hosting panel or ask the provider to do it. If you administer the server, install a compatible Imagick extension and its ImageMagick dependency for the web-serving PHP runtime, then confirm the result in Site Health.
Check whether Imagick is already active
- In WordPress administration, open Tools → Site Health → Info → Media Handling.
- Check the Active editor entry and the Imagick and ImageMagick version fields.
If the active editor is WP_Image_Editor_Imagick and version details are present, WordPress is using Imagick. The active editor may instead be GD, which WordPress documents as the default in relevant environments. Site Health reports server information; it does not enable extensions. WordPress explains the screen in its Site Health screen documentation.
Enable Imagick on managed hosting
Use the host’s PHP extension controls
Look in your hosting control panel for a PHP selector or PHP extensions section. Select the PHP version assigned to your WordPress site and enable Imagick if the provider offers it. Panel names and available extensions vary by host.
Ask your provider if there is no Imagick option
Extension availability and server configuration are often managed by the hosting company. Send support a request such as:
Free tools Windows power users keep installed
One-click scans. No signup required.
#1 Best Overall
Please confirm whether Imagick is available for the PHP version assigned to my WordPress site. If it is, please enable the Imagick PHP extension for that runtime and confirm the ImageMagick version. I will verify the active editor in WordPress Site Health.
WordPress notes that Imagick availability depends on the hosting company. Its Hosting Handbook lists ImageMagick as the extension’s dependency.
Enable Imagick on a server you administer
Install the Imagick PHP extension using the package source and instructions maintained for your operating system and PHP distribution. The extension must match the PHP runtime serving the website; installing it only for command-line PHP may leave WordPress unable to load it. Package names and service reload steps differ across server stacks, so there is no safe universal command.
The WordPress Hosting Handbook lists ImageMagick 6.2.4 or later as the dependency floor and recommends ImageMagick 7.1 or later. The lower figure is not a recommendation to install an outdated release. Use the handbook alongside your distribution’s package instructions and the PHP Imagick installation documentation. The Ubuntu guide to installing and configuring WordPress covers a server setup, but does not provide a universal Imagick-specific package command.

After the host or administrator enables the extension, return to Tools → Site Health → Info → Media Handling. Confirm that the active editor is WP_Image_Editor_Imagick and that Imagick and ImageMagick version details appear. These fields help identify PHP-side image-generation problems.
If Imagick is still missing
- Confirm that the extension was enabled for the PHP version assigned to the site, not a different version.
- Check that the web-serving PHP runtime loads it; a command-line PHP installation can use a separate configuration.
- If the host manages PHP, ask support to confirm that the extension is loaded for your account’s assigned runtime.
Check format support, PDF thumbnails, and security policy
Imagick’s underlying ImageMagick installation and configuration affect which image operations and formats are available. If your site needs PDF thumbnails, the WordPress Hosting Handbook says Ghostscript 10.0 or later enables that capability through Imagick/ImageMagick; Ghostscript is not a general requirement for ordinary image uploads.
For a public website, review the ImageMagick policy configured by the host or server administrator. ImageMagick recommends environment-appropriate resource limits and restrictions on unnecessary formats or coders. Strict policies can also block legitimate operations, so check the formats your site actually needs before tightening restrictions. See ImageMagick’s security policy guidance.

| What to compare | Managed hosting | Self-managed server |
|---|---|---|
| Who enables PHP extensions | The provider, through its control panel or support team; controls vary. | The server administrator, using the server’s operating-system and PHP package instructions. |
| PHP version compatibility | Confirm Imagick is available for the PHP version assigned to the site. | Install an extension compatible with the PHP runtime serving the site. |
| ImageMagick version and formats | Ask the provider which version and formats are available. | Check the installed version and configuration against the site’s format needs. |
| PDF thumbnails | Ask whether Ghostscript 10.0 or later is available if PDF thumbnails matter. | Install and configure Ghostscript if PDF thumbnail generation is needed. |
| Security and resource limits | Ask which ImageMagick policy and limits apply. | Set and maintain an appropriate ImageMagick policy and resource limits. |
| Updates and troubleshooting | Typically handled by the provider within its hosting environment. | Handled by the server administrator. |
These are differences in responsibility and capability, not a blanket ranking of hosting types. The right route depends on who controls the PHP runtime your site uses.
Check PHP compatibility separately from host availability
cPanel states that Imagick PECL module version 3.5 and higher supports PHP 8.x, but this compatibility statement does not mean every hosting provider offers the extension. WordPress’s current requirements page recommends PHP 8.3 or later, MariaDB 10.11 or later or MySQL 8.0 or later, and HTTPS. Those platform recommendations do not replace checking whether Imagick is installed for your site’s active PHP runtime. The cPanel statement was updated December 18, 2024; provider availability remains a separate question.
