Webp Transformer

Convert images from library to webp and resize them during upload

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>
