Biggest opportunity: Add “plus”, “mime types” and “mime” to your wp.org tags. You rank #10, #13 and #16 for them without listing them, close enough for a declared tag to move you up. WordPress.org counts only your first five tags, so with 4 listed these are the slots worth spending.

How it's measured →6.1%
of downloads still active
At least 5K of 81.5K lifetime downloads are still running, above its category: the median Media plugin keeps 0.8%, across 2,317 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Media plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 5 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

wp.org is where the directory puts the plugin for that search. On merit is where it would sit if results were ranked on rating, support and updates, without the install boost. The last column is how far the wp.org position moved, from our first reading in the last 90 days to the latest.

What to do about it
- Add “plus”, “mime types” and “mime” to your wp.org tags. You rank #10, #13 and #16 for them without listing them, close enough for a declared tag to move you up. WordPress.org counts only your first five tags, so with 4 listed these are the slots worth spending.
- One page off on “avif”. #13 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.

It’s a refreshingly easy to handle plugin and it works perfectly well. It does what it needs to!

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?
