WebP Express

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 · 97% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

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. A declining trend compresses what a buyer would pay.

   It works. It’s seamless. It provides clear explanations of all the options. It’s done with the nicest, selfless hacker mindset there is.

   While many other optimization plugins try to reduce the server work and get you to use their cloud solution (and pay), this plugin does the most suitable job. Converts the files on request from the end user, doing it on the server. Creating the required sizes and later serving the other users those images. Practically, if you upload the image and preview your post/page, the converted file is there and no more waiting. No payments, no bloatware. With popular plugins that’s mostly not the case as they do the bulk conversion by sending the files to their servers and of course – if you pay for it – send back the files when they can. It can take quite some time and often having issues as the sync can run into various troubles on your or their side. Meaning that with other plugins you may have to wait to have optimized images served (if ever). With this one, you have it there from the start. Fantastic job!

   Works perfectly well. Just make sure to read the documentation and that your server has the proper rules enabled.
