Plus WebP


Generate WebP

  • Generate WebP file when adding image file in Media Library.
  • Generate WebP from all the images by async/await.
  • Optionally, Can replace image files with WebP when adding new media, and delete the original image file. Also, when generating all images, the original image file ID will be overwritten as WebP and the original image file will be deleted. All URLs in the content are also replaced.


WP-CLI commands are available. If you have a large number of files, WP-CLI commands is more reliable.

After updating to version 4.09, I had to turn off the plugin, as it began to change the sender name for all letters coming from my site to mail using the following template “[ Site name ] WebP generate for Plus WebP”. After deactivating the plugin, the problem was resolved. Your plugin is very good! I gave it 2 stars just to get your attention.

This is great plugin to save my server space! Dear developer, I prefer to donate by paypal, usdt or stripe instead of inputting my credit card elsewhere.

The plugin works, converts images to webp but also uses the apache PHP LoadFromFile that loads the images from file rather make http request, which means it will change the canonical of the images. Which means your articles and website will disappear from Google search, which will kill the traffic and the website finally. This happened to my website till I traced the solution down to this plugin. You’ll post and it just won’t show on Google search even though all is green on GSC because of this plugin. If you notice your website traffic is dying or your website doesn’t show on Google, try removing this plugin and check your keywords acquisition on ahrefs.

Works great! Just be careful with the “WebP replacement of images and contents” setting. Do you REALLY want to remove all your old JPG files?
