Update activity

How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.

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

Estimated value

What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.

Est. annual revenue

N/A

Est. acquisition value

N/A

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 small install base leaves thin data to model from. The recent download trend is too spiky to read.

    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?
