Biggest opportunity: Swap “image” and “svg” for “postmeta” and “convert webp”. “image” isn't earning its slot: you're not in the first 24 results for its own search. “postmeta” sits at #13 untagged, close enough for a declared tag to move it up. “svg” isn't earning its slot: you're not in the first 24 results for its own search. “convert webp” sits at #18 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

How it's measured →37%
of downloads still active
At least 4K of 10.8K lifetime downloads are still running, above its category: the median Performance plugin keeps 1.4%, across 1,104 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Performance 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 1 release 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.

How it's tracked →Directory searches this plugin turns up in, and which way each one is moving. WordPress.org publishes no history of search positions, so this starts the day we first tracked a keyword and never backfills.
Not enough tracked days yet to call a direction. Momentum needs at least three keywords measured a week or more apart.
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.
| Keyword | wp.org | On merit | wp.org move, 90 days |
|---|---|---|---|
| conversion your tag | #5 | #15 | down 1 |
| ico your tag | #11 | #12 | down 1 |
| webp your tag | #20 | #22 | 0 |
| postmeta | #13 | #15 | 0 |
| convert webp | #18 | #21 | 0 |
| image your tag | Not in the top 24 | ||
| svg your tag | Not in the top 24 | ||
7 searches this plugin appeared in over the last 90 days, 5 listed. 2 left out as unrelated or noise (years, numbers, stray words). 2 of its tags aren't in the top 24 for their own search.
What to do about it
- Swap “image” and “svg” for “postmeta” and “convert webp”. “image” isn't earning its slot: you're not in the first 24 results for its own search. “postmeta” sits at #13 untagged, close enough for a declared tag to move it up. “svg” isn't earning its slot: you're not in the first 24 results for its own search. “convert webp” sits at #18 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.
- One page off on “ico”. #11 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.

What its installed base runs
via wordpress.orgShare of active installs on each version of this plugin · 92% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.
Estimated active installs
The public count shows “4K+”. Our estimate pins where the real number sits.
Crossed into this band 43 days ago and a band this size takes about a year or more to cross, so the real count is still just over 4K.
At the current install trend, crossing 5K+ in roughly 78 days.

Super Plugin – macht was es soll. Ich hoffe es wird weiterhin aktualisiert und weiterentwickelt!
Read on wp.org ↗ - ★★★★★ bokibe11mo ago
Some users including myself, have Fatal errors with this plugin. We can’t delete media files without disabling the plugin first. The support log show no answer for more than a month and the last update was 3 months ago. I can be wrong but I presume this plugin is dead. Shame, I liked this plugin. And I suspect that one 5 star rating was not a real rating. This topic was modified 7 months ago by bokibe.

If you’re aiming to speed up your site and reduce image load times, this plugin is definitely a solid choice. Avaliação em Português Este plugin cumpre tudo o que promete e ainda vai além. Ele converte as imagens diretamente na Biblioteca de Mídia, incluindo as thumbnails, o que é um grande diferencial para otimização de desempenho. As imagens WebP geradas e usadas no site não apresentam quebras nem problemas de exibição, garantindo uma experiência de usuário tranquila. O processo de conversão é eficiente e se integra perfeitamente ao WordPress, facilitando o gerenciamento das imagens sem complicações.

I have tried dozens of image compressor plugins and most of them had fallen to the subscription model. That’s strange given that compression is not a resource-intensive task. This plugin brings back the true spirit of WordPress. It’s simple, intuitive, and free for everyone. It’s so good, I even made a video for this plugin.
