Yeah, that doesn’t sound right.
When you say that Imagick / Gmagick are operational, I take it that you see the green checkmark on these rows in the options page, right?
As for Imagick:
The Imagick extension should be able to detect quality PECL >= 2.2.0.
The problem *could* be that you are on an older version.
Can you check your PECL version for me?
version-check.php:
<?php
echo 'Imagick PECL version:' . phpversion("imagick");
echo 'Imagick version:' . print_r(\Imagick::getVersion(), true);
?>
As for Gmagick:
Gmagick extension actually doesn’t support detecting image quality: https://bugs.php.net/bug.php?id=63939
However, WebP Express does try to use gmagick for detecting quality, by executing gmagick with exec(). Exec calls are probably not allowed on your server.
I shall update the help texts…

The “auto” option is available, when WebP Express detects that it can detect the quality of a test-image.
But actually, it is possible to have “auto” quality with imagick extension, without being able to detect the quality: If no quality is set, imagick will detect quality of source and use that.
So – I could do something to allow auto quality with imagick, even when quality detection is unavailable. I shall make it possible to override the quality option for imagick, allowing it to be set to “auto”. I already have such functionality for the Remote WebP Express conversion method.
Sorry for the delayed reply.
>Yes , I see the green marks.
>Sorry I have no knowledge with PHP whatsoever, some instructions on how to check for PECL version? My web host is Hostinger, if that helps.
To check pecl version do this:
1: Create a file “versioncheck.php” in the root folder with the following content:
<?php
echo 'Imagick PECL version:' . phpversion("imagick");
echo 'Imagick version:' . print_r(\Imagick::getVersion(), true);
?>
2: Point your browser to the php. Ie: http://example.com/versioncheck.php
Here you go:
Imagick PECL version:3.4.3RC4Imagick version:Array ( [versionNumber] => 1684 [versionString] => ImageMagick 6.9.4-10 Q16 x86_64 2017-05-23 http://www.imagemagick.org )
Thanks!
This probably means I have a bug to fix.
However, in the upcoming version of WebP Express, I have implemented that you can override the general quality option and set it to “auto” for imagick. So you don’t have to wait for the bug to be resolved. I’m releasing v 0.8 today or tomorrow.
0.8.0 is out, and you should now see the auto option, when you click “configure” on the imagick conversion method!
