Ultimate Image Optimization Helpers

Optimize your images the right way—maintain the quality of your resized images.

JS Morisset

Have you noticed that WordPress creates small images that are a bit “fuzzy” – nothing like the nice sharp original you uploaded?
After resizing an image, the image must be sharpened but WordPress doesn’t do any sharpening, so the resized image remains a bit “fuzzy” – not what you want for a featured image or shared image on social sites! The WPSSO Tune WP Image Editors (WPSSO TIE) add-on provides this missing WordPress image sharpened feature – it automatically applies sharpening to all JPEG images resized by the WordPress ImageMagick library.
Compatible with all image compression / optimization plugins:
Image sharpening is applied during the WordPress resize operation so the resulting images can still be optimized with any compression / optimization plugin.

<h3>WPSSO TIE Add-on Features</h3>
Extends the features of the <a href="https://wordpress.org/plugins/wpsso/" rel="ugc">WPSSO Core plugin</a> (required plugin).
Applies adjustments to resized images (aka thumbnails) using ImageMagick:
<ul>
<li>Enable or disable image adjustments / sharpening for resized images.</li>
<li>Uses a better compression quality of 92% (WordPress default is 82%).</li>
<li>Applies a default amount of sharpening values to all resized images.</li>
</ul>
Optionally select different primary / secondary image editor(s) for WordPress:
<ul>
<li>GD Only</li>
<li>GD and ImageMagick</li>
<li>ImageMagick Only</li>
<li>ImageMagick and GD (WordPress default)</li>
</ul>
Optionally fine-tune the image filter priority and image adjustment options:
<ul>
<li>Modify the default ‘image_make_intermediate_size’ filter hook priority.</li>
<li>Enable / disable contrast leveling.</li>
<li>Increase / decrease the compression quality percentage.</li>
<li>Adjust sharpening values individually (sigma, radius, amount, threshold).</li>
</ul>
