Biggest opportunity: Swap “performance” for “compress images”. “performance” isn't earning its slot: you're not in the first 24 results for its own search. “compress images” sits at #4 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

of downloads still active
At least 1M of 16.4M lifetime downloads are still running, above its category: the median Performance plugin keeps 1.4%, across 1,105 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 9 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.

What to do about it
- Swap “performance” for “compress images”. “performance” isn't earning its slot: you're not in the first 24 results for its own search. “compress images” sits at #4 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

After using this plugin for over a year, I can only say it leaves much to be desired. The compressed image quality is overall poor, even if you spend lots of credits testing trying to get it right. It can take a long time to process even a single image, sometimes taking more than a minute. Batches seem to offer a better overall performance gain, although the poor image quality remains an issue. I was led to believe all image processing was offloaded to the cloud, which may be true, although the CPU utilization increases quite a bit when this plugin is processing images. Finally, there are frequent failures where the images simply do not get optimized. There is no auto-retry, so you must manually intervene when this happens. There are other issues as well, such as not being able to determine how many credits each site has used if several small sites share a plan. Elementor suggested logging into each site, count how many items need to be optimized and how many were optimized. What?!? This plugin was poorly designed and poorly implemented. I expected much better from a company like Elementor.

This is another bait and switch plugin where they offer a service for free for a limited time, then stop providing the service because they want you to go pro. No thank you. I can resize my own photos on my laptop myself, it really isn’t that hard to do. If I had to pay for every single plugin on here I would be broke.

A couple days ago, I Paid $60 to purchase an upgrade for Elementor as part of my WordPress. It had a feature called Image Optimizer in side it. I worked one time then now it says I got to upgrade and buy it again after two days. It won’t let me optimize any more images. This is apparently a scam. There does not seem to be any way to contact anyone for help. I will contact my credit card to dispute the charge. But I am not sure I will ever get anything back. DO NOT TAKE A CHANC E WITH THIS COMPANY – THEY ARE A SCAM.

Blocking all the images in a WordPress site’s media library without prior notice and demanding money to unblock them constitutes extortion (Article 312.1 of the French Penal Code), punishable by 7 years in prison and a €100,000 fine. Can anyone provide me with the contact information for the person responsible for the Image Optimizer plugin? Le fait de bloquer l’ensemble des illustration de la médiathèque d’un site wordpress sans information préalable et d’exiger une somme d’argent pour en permettre le déblocage est une extorsion de fonds (article 312.1 du Code Pénal français) passible de 7 ans de prison et de 100 000 € d’amende. Quelqu’un peut-il me donner les coordonnées du responsable du Plugin Image Optimizer ?

Extremely poor experience. This plugin ruined my homepage layout immediately after activation. To make matters worse, I encountered an error when trying to deactivate it. I deeply regret installing this.

Tried it for image compression on my site. It does reduce size and helps a bit with loading. Setup was easy, too. But sometimes optimization feels a bit slow. Still ok for basic use.
