Technical Specs

Quick Verdict

Choose ezCache. With an 80% five-star rating and 0% one-star reviews, it delivers a complete performance stack, page caching, Redis, Critical CSS, and WebP, in one plugin. Image Optimizer focuses only on image tasks, but its 77% one-star rate signals serious reliability issues. For most WordPress sites, ezCache is the smarter, safer investment.

Feature Comparison: Image Optimizer vs ezCache

Who Should Use Image Optimizer

• Teams focused exclusively on image optimization, such as converting images to WebP in WordPress, Image Optimizer handles bulk conversion and on-upload processing, which is ideal for media-heavy sites with 100,000+ image files.
• Anyone who needs AVIF output. Image Optimizer is one of the few plugins that can convert images to AVIF, a format that saves 30-50% more bandwidth than WebP on supported browsers.
• Sites running WooCommerce with thousands of product photos. The auto-resize feature, which scales images on upload, helps keep product galleries fast without manual work, critical when you need image compression for WooCommerce product images at scale.

Who Should Use ezCache

• Site owners who want a single plugin for full performance optimization. ezCache bundles page caching, Redis Object Cache, and CSS/JS minification, replacing three separate plugins with one tool rated 4.5 out of 5 by users.
• Developers managing high-traffic WordPress sites. The built-in Redis Object Cache support reduces database queries by storing frequent lookups in memory, a feature that can cut page load times by 40% or more on busy stores.
• Anyone who values stable, well-reviewed software. ezCache holds an 80% five-star rating with zero one-star reviews, suggesting consistent reliability across different hosting environments.

Community & Support

Image Optimizer shows a stark user satisfaction gap: only 12% of reviews are five-star, while 77% are one-star. That distribution indicates widespread frustration, though the plugin's small support sample (1 open thread in 2 months) means we can't draw conclusions about response times. ezCache tells a different story, 80% of its ratings are five-star and 0% are one-star, a pattern that suggests most users find the plugin works as advertised. Neither plugin has enough recent support thread data to compare ticket handling.

Verdict: Image Optimizer or ezCache for WordPress sites?

Pick Image Optimizer if your single need is converting images to AVIF or running bulk image compression without touching other performance settings. Its auto-resize feature (used by 1.0M+ installs) can save hours on large media libraries, but you'll need to accept the 77% one-star rating risk.

Pick ezCache if you want a complete performance solution. It handles caching, Redis, Critical CSS, and WebP images in one package, and its 80% five-star rating shows users trust it. For 9 out of 10 WordPress sites, ezCache is the better choice because it solves more problems with less complexity.
