Overview
WordPress Image Optimizer
Optimus reduces the file size of uploaded media files automatically. Depending on the image and format, reductions in size of up to 70% are possible. Several kilobytes can be saved per image—these savings contribute positively to the performance of the blog website. What’s most impressive about the compression technology: the quality of the images is maintained.
There are three different versions of Optimus:
- Optimus (Free) as base version with limitations (e.g. max of 100kb)
- Optimus HQ (Premium) with expanded functionality for personal projects
- Optimus HQ PRO (Premium) as professional solution for customer websites

Not very effective
by alexio·6 years ago
The 100kb limit of the free version is very limiting and mostly serves like a demo. My disappointment was that even though i had the premium version and i optimized the images, google pagespeed still had the message that my images could be smaller.

Pourquoi perdre du temps quand un outil peut vous en faire gagner…
Si vous avez des images trop lourdes qui peuvent ralentir votre site, c’est l’outil idéal.

You should purchase this plugin!
by Panos Sakalakis·7 years ago
A simple, fast and easy to use plugin that has great features to offer. I’ve purchased a key for the Pro version a few days ago and converted all my pictures to webP. My blog is faster than ever. If you care about your site’s speed, stop what you’re doing and purchase a key!
Es war einmal…

ein gutes Tool, erfunden von einem der Besten -> Sergej Müller… doch nun macht das absolut keinen Sinn mehr. Warum? Hatte man mal eine HQ Lizenz und möchte diese nicht verlängern, so versagt das Plugin anschließend seinen Dienst komplett und bedient nicht mal mehr die “freien Features”.
