Bottom line: EWWW Image Optimizer handles image compression and delivery. ImageSEO handles image SEO — alt text, file naming, and Open Graph. They are complementary, not competitors.
EWWW Image Optimizer is a WordPress plugin that compresses images on your own server (no external API required). It supports WebP conversion, lazy loading, and ExactDN CDN. EWWW does not generate alt text or rename files for search engines.
ImageSEO is a WordPress plugin that uses AI to make images rank in Google Image Search. It automatically generates descriptive alt text, renames image files with SEO-friendly keywords, and creates Open Graph images. ImageSEO does not compress images — it makes them discoverable.

EWWW Image Optimizer reduces image file sizes so pages load faster. ImageSEO adds the SEO metadata layer — so images rank in Google Image Search. A perfectly compressed image with a filename like IMG_4821.jpg and no alt text gets zero image search traffic. ImageSEO fixes that automatically.
EWWW Image Optimizer’s strengths: server-side compression (no API), WebP, ExactDN CDN, no monthly image limits. If your primary goal is reducing page load time and bandwidth costs, EWWW Image Optimizer is a solid choice for that specific job.
ImageSEO wins on everything related to image discoverability: AI-powered alt text at scale, automatic SEO file renaming, and Open Graph automation.
