ImageMagick Sharpen Resized Images

2025-08-06 WP免费插件库 5

Tired of having blurry lifeless WordPress images? This plugin sharpens resized JPG image uploads and it works with ImageMagick so it keeps quality, EXIF information and color profiles. It also maintains the crops and other image proportions.

Bonus: It enables you to have automatic contrast leveling too.

Installation Instructions

Upload imagick-sharpen-resized-images.php to the /wp-content/plugins/ directory.
通过WordPress的“插件”菜单激活插件。
In your WordPress Settings you’ll have a new admin entry: IM Sharpen Images.

Check https://codex.wordpress.org/Managing_Plugins#Installing_Plugins for more detailed installation instructions.

Are there any system requirements?

Your host needs to have the imagick PHP module installed (and, of course, the ImageMagick program itself).
The imagick PHP module is NOT a WordPress plugin, but a module for PHP. The plugin has a built-in check for this imagick PHP module.

If you don’t have the imagick PHP module installed you can still sharpen your images by using the Sharpen Resized Images plugin. It sharpens the images by using lower quality GD, so it strips EXIF data and it strips color profiles.

I don’t see any sharpening, why?

After you enable the plugin it will only sharpen new uploads. If you want to sharpen your already uploaded images you will also need the Regenerate Thumbnails plugin.
Make sure to have not only the PHP module but also the ImageMagick software installed on the server (most servers have it though).
Still no differences? Clear your browser cache.
If you’re using Varnish cache or other server caches, empty them.
Sharpening only works with JPG files.

How can I adjust the amount of sharpening?

I defined the for me optimal amount of sharpening. You can change it though by going in your WordPress Admin Settings to the IM Sharpen Images entry. The default settings are fine though (Radius 0, Sigma 0.5, Amount 1, Threshold 0). I defaulted the threshold to 0 because personally I want to retain fine skin details in my photos. You can change it to 0.05 for noisy images if it sharpens noise too much.

How can I reset the plugin to the default values?

Just deactivate the plugin and (re)activate it. This will restore the default values.
