  • It works flawlessly.

    For Nginx, I had to make a change to the .conf file, and then everything worked perfectly. The only caveat is that the instructions state you need to make changes to the http{} section, but that section isn’t present in all configuration files. For example, in Docker, configurations are included via http {include /etc/nginx/conf.d/*.conf;}, meaning that the entire configuration file is already contained within the http section in the main configuration file, and you won’t see it as a separate section.

  • A Brilliant Piece of Work

    I am highly impressed by this well thought out and elegant module. It works perfectly for me

  • Working great!

    Working great! It was challenging for me to optimize the existing images, but it makes it simple.

  • Fantastic plugin and easy to get working with cropping plugins

    This plugin is a bit of a game changer for me!Having extensively used custom images sizes and the Crop-Thumbnails plugin for many clients to allow them much better control of their images, i ran into a big problem when it came to serving images as WebP.Images were cropped automatically upon upload (and of course converted to WebP) but when adjusting the crop position later on, the WebP converted images were never updated, effectively breaking the cropping function.But this plugin is not only fast, efficient and free (amazing work guys!) but has a completely life saving function: $images_to_webp->convert_image()Using this i was easily able to connect Crop-Thumbnails up and have it so whenever a user adjusts a crop, that image is re-converted to WebP.Thank you for such a fantastic plugin!
