Images to WebP

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin · 59% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Modeled within the band wp.org reports; tightens as we track daily.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price.

   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.

   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!

   Just came across your profile because i use your smooth scroll plugin on many customers of mine. So i saw that you have some other plugins and now im using beside the smooth scroll plugin also the CPT Plugin and this WebP Plugin.All Plugins are super simple and very easy to use. They also all work as thei should. Perfect! Thanks for your work!Im corious if you could also add avif as supported format 🙂

   You are getting feedback about SEO issues likely because when the “delete” option is selected the plugin needs to remove the http_accept line from the .htaccess rules (also the nowebp line makes no sense if the delete option is used).Since the desktop crawler agents won’t pass the http_accept rule the search crawlers will get 404 errors trying to load deleted originals.After a few years of WebP conversion experience I’ve found the reason some images come out larger is because they were compressed far too lossy (almost always a small JPG), but there is a command line option for CWebP that will match the original file size so you can do a full conversion to WebP.
