The plugin is easy to use but the tiny free file limit feels like a demo.

Reviews
what people actually sayOptimus is a straightforward image optimization plugin with a loyal base of users who appreciate its ease of use and speed improvements, but it is held back by a very restrictive free-tier file size limit, questions about real-world effectiveness, and reports of poor support.
What people like
- +Easy to set up and use with minimal configuration required×5
- +Noticeably reduces image file sizes and improves site load speed×6
- +Works automatically in the background after installation×3
- +Paid/premium upgrade considered worthwhile by users who purchased it×2
Common complaints
- −Free version has a 100 KB per image limit, making it barely functional for real-world use×3
- −Compression does not meaningfully improve Google PageSpeed Insights scores, even on the premium version×2
- −Bulk optimization process interrupts mid-run and requires manual page reloads to continue
- −If a paid licence lapses, the plugin reportedly stops working entirely, including previously free features
- −Customer support described as unresponsive or unhelpful×2
- −Plugin version was reported as outdated (several months behind)
- −Does not optimize images uploaded via the WordPress API, only through the standard media uploader
