Bottom line: Optimole handles image compression and delivery. ImageSEO handles image SEO — alt text, file naming, and Open Graph. They are complementary, not competitors.
Optimole is a cloud-based image optimisation service with a WordPress plugin. It delivers images via a CDN, auto-resizes them for different screen sizes, and converts to WebP. Optimole does not generate alt text or optimise image file names for SEO.
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.

Optimole 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.
Optimole’s strengths: real-time CDN delivery, adaptive images, lazy loading, good free tier. If your primary goal is reducing page load time and bandwidth costs, Optimole 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. It’s especially powerful for WooCommerce product image SEO. Run a free image SEO audit or try the free alt text generator to see what’s missing on your site.

Only indirectly. Faster load times improve Core Web Vitals, a minor ranking factor. Optimole does not generate alt text, rename files, or add structured data — the elements that directly affect Google Image Search rankings.
ImageSEO does. It uses AI to automatically write descriptive alt text for every image in your WordPress media library — in bulk. Optimole does not include this feature. Try the free ImageSEO alt text generator to see it in action.
