What is Compress images for WordPress?
WordPress sites are notoriously image-heavy, and compression plugins add server load. Pre-compressing images to WebP at ~82% quality, capped at 1920px, gives you faster pages without another plugin.
Shrink44 does it locally: pick WebP output, ~82% quality, cap the longest side to what you need, and bulk-process the whole set into a single ZIP — without uploading anything.
