How to Enable Webp Image Format for Use with ImageMagick on cPanel WHM Server

This article provides a guide for how to enable WebP image format for use with ImageMagick on cPanel WHM server. This guide is intended for root-level cPanel VPS or cPanel Dedicated Server administrator.

What is WebP?

WebP is an open-source image file format developed by Google that supports both lossy and lossless image compression. A WebP file is an image file in the WebP format. WebP is seen as a "modern image format" and as the eventual successor to JPEG and other earlier image file formats.

What is ImageMagick?

ImageMagick is a free and open-source cross-platform software suite for displaying, creating, converting, modifying, and editing raster images.

Since 1987, ImageMagick has become a signature open-source image-editing software, used as both a stand-alone project as well as an ancillary package, bundled with other popular softwares. As such, the ImageMagick package is considered a dependency of many common website softwares, such as WordPress and WHMCS. Therefore, it may be helpful to install on cPanel WHM servers.

You can enable WebP Image Format for use with ImageMagick on cPanel/WHM servers per PHP version or for all PHP versions.

Install ImageMagick on cPanel/WHM Server for Specific PHP Versions

NOTE: This guide is strictly for use with CentOS 7 cPanel/WHM servers.

To install ImageMagick to a cPanel/WHM server for specific PHP version, perform the following steps:

Remove the existing ImageMagick packages:

yum remove ImageMagick ImageMagick-devel -y

Install the EPEL repository (Remi Repo Requirement):
```
yum install epel-release -y
```
Install the Remi Repository:
https://blog.remirepo.net/pages/Config-en
```
wget https://rpms.remirepo.net/enterprise/remi-release-7.rpm
rpm -Uvh remi-release-7.rpm
```
NOTE: You'll notice that this step (#4) omits the download and install of the EPEL rpm that is shown in the Remi Repo installation instructions at the link above. It has been ommited because the EPEL repository has already been installed via yum in step #3 above.
As mentioned earlier in this article, disable the Remi Repository so that packages can only be explicitly installed from it:
```
yum-config-manager --disable remi-safe -y
```
Install ImageMagick directly from the Remi Repository by enabling it only for this one transaction:
```
yum install --enablerepo=remi -y ImageMagick7 ImageMagick7-devel
```
Find the binaries for PECL for all versions of PHP that you have installed:
```
find /opt/cpanel/ -iname pecl | grep bin
```
For each desired PHP version, uninstall (if needed) and then install the ImageMagick PHP Extension. PHP 74 is used in this example:
```
/opt/cpanel/ea-php74/root/usr/bin/pecl uninstall imagick
/opt/cpanel/ea-php74/root/usr/bin/pecl install imagick
```
NOTE: When prompted for the ImageMagick prefix, just press enter to and allow it to autodetect.

Check the output to confirm PECL binaries of the cPanel installation:

root@cpanel [~]# find /opt/cpanel/ -iname pecl | grep bin
/opt/cpanel/ea-php56/root/usr/bin/pecl
/opt/cpanel/ea-php70/root/usr/bin/pecl
/opt/cpanel/ea-php71/root/usr/bin/pecl
/opt/cpanel/ea-php72/root/usr/bin/pecl
/opt/cpanel/ea-php73/root/usr/bin/pecl
/opt/cpanel/ea-php74/root/usr/bin/pecl
/opt/cpanel/ea-php80/root/usr/bin/pecl
/opt/cpanel/ea-php81/root/usr/bin/pecl
/opt/cpanel/ea-php82/root/usr/bin/pecl
root@cpanel [~]#

where ea-phpXX represents the installed PHP versions.

For each PHP version, run the following command (modify the commands for the PHP versions):
```
/opt/cpanel/ea-phpXX/root/usr/bin/pecl install imagick
```

Example commands:

/opt/cpanel/ea-php56/root/usr/bin/pecl install imagick
/opt/cpanel/ea-php70/root/usr/bin/pecl install imagick
/opt/cpanel/ea-php71/root/usr/bin/pecl install imagick
/opt/cpanel/ea-php72/root/usr/bin/pecl install imagick
/opt/cpanel/ea-php73/root/usr/bin/pecl install imagick
/opt/cpanel/ea-php74/root/usr/bin/pecl install imagick
/opt/cpanel/ea-php80/root/usr/bin/pecl install imagick
/opt/cpanel/ea-php81/root/usr/bin/pecl install imagick
/opt/cpanel/ea-php82/root/usr/bin/pecl install imagick

After each command, confirm the prefix of ImageMagick installation (enter "Return" to use default):
```
Please provide the prefix of ImageMagick installation [autodetect] :
```
Repeat for each PHP version
When finished, run the following command to restart PHP-FPM (if applicable):
```
/scripts/restartsrv_apache_php_fpm
```

Install ImageMagick on cPanel/WHM Server for All PHP Versions

To install ImageMagick to a cPanel/WHM server for all PHP versions (installed and configured in EasyApache), follow the steps below:

SSH the server as root user

Run the following command to install the packages AND configure enable PHP extensions for all possible PHP versions:

yum remove ImageMagick ImageMagick-devel && 
yum install epel-release -y && 
wget https://rpms.remirepo.net/enterprise/remi-release-7.rpm && 
rpm -Uvh remi-release-7.rpm && 
yum-config-manager --disable remi-safe && 
yum install --enablerepo=remi -y ImageMagick7 ImageMagick7-devel && 

for php in $(whmapi1 php_get_installed_versions|grep -oE '\bea-php.*') ; do 
    /opt/cpanel/$php/root/usr/bin/pecl uninstall imagick;
done

for php in $(whmapi1 php_get_installed_versions|grep -oE '\bea-php.*') ; do 
    /opt/cpanel/$php/root/usr/bin/pecl install imagick;
done

After each command, confirm the prefix of ImageMagick installation (enter "Return" to use default):
```
Please provide the prefix of ImageMagick installation [autodetect] :
```
Repeat for each PHP version
When finished, run the following command to restart PHP-FPM (if applicable):
```
/scripts/restartsrv_apache_php_fpm
```

Conclusion

You have now enabled WebP image format for use with ImageMagick on cPanel/WHM server. If you face any difficulties, please open a support ticket for assistance.
