WordPress WebP plugin

The first audit I run on any underperforming WordPress site is the image inventory, because image weight is almost always the biggest unfixed problem. WebP usually shaves 25–35% off a JPEG or PNG at the same visible quality. This plugin does the conversion server-side on every new upload: your hosting account, your CPU, no third-party API key to renew. Originals stay on disk, so nothing is destroyed if you ever need to roll back. What you get Automatic WebP generation for every new .jpg, .jpeg, and .png uploaded to the Media Library Original file kept on disk: non-destructive, fully reversible <picture> output added to the front end so browsers that support WebP get the smaller file and older browsers fall back to the original Quality setting baked in (default 82), picked because it's the sweet spot between size and visible artefacts on real content No external API, no monthly subs
