Switching from WebP Conversion: common questions
What is the best alternative to WebP Conversion?
Optimus is the closest match: it shares the same WordPress.org tags and has 30,000+ active installs with a 4.2 out of 5 rating.
Which WebP Conversion alternative has the most users?
EWWW Image Optimizer, with 1 million+ active installs reported by WordPress.org.
Which WebP Conversion alternative is rated highest?
Converter for Media, rated 4.9 out of 5 by 1,099 reviewers. Only plugins with at least 50 reviews are counted.
Are these WebP Conversion 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 WebP Conversion 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 WebP Conversion 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
Optimus is the closest match to WebP Conversion by the data we track, and EWWW Image Optimizer has the widest reach with 1 million+ active installs. Perfect Images shipped the most recent release, on September 5, 2026. The list is rebuilt every day from WordPress.org, so a plugin that stops being maintained drops out on its own.
