Switching from Cimo: common questions
What is the best alternative to Cimo?
EWWW Image Optimizer is the closest match: it shares the same WordPress.org tags and has 1 million+ active installs with a 4.8 out of 5 rating.
Which Cimo alternative has the most users?
EWWW Image Optimizer, with 1 million+ active installs reported by WordPress.org.
Which Cimo alternative is rated highest?
CompressX, rated 5.0 out of 5 by 197 reviewers. Only plugins with at least 50 reviews are counted.
Are these Cimo alternatives free?
Every plugin listed here is free to install from WordPress.org. Where WordPress.org marks a plugin as commercial, the developer also sells a paid version or add-ons, and that is shown on each plugin.
How are alternatives chosen?
Automatically, from WordPress.org data: plugins that share a category top 10 with Cimo score highest, then plugins that appear in the same WordPress.org rankings, then plugins with the same tags, weighted so rare tags count more than common ones. Plugins by the same author and plugins rated under 4.0 are left out.
How we choose these alternatives
Nothing on this page is picked by hand. Every day we walk the whole WordPress.org directory, then score every plugin against Cimo on three signals: sharing a category top 10 counts most, then appearing in the same WordPress.org rankings, then carrying the same tags, with rare tags counting for more than common ones like "wordpress". Plugins by the same author are excluded, so an author's own add-ons cannot fill the list, and so is anything rated below 4.0 or with fewer than 100 active installs. The ten highest scores are what you see, in that order. Full methodology.
The bottom line
EWWW Image Optimizer is the closest match to Cimo by the data we track, and EWWW Image Optimizer has the widest reach with 1 million+ active installs. Converter for Media shipped the most recent release, on October 14, 2026. The list is rebuilt every day from WordPress.org, so a plugin that stops being maintained drops out on its own.
