Smush is one of the most popular free WordPress image plugins — but its image SEO features are basically non-existent. If you’re looking for a Smush alternative that actually improves your rankings in Google Image Search, ImageSEO does what Smush doesn’t: AI alt text, SEO file naming, and Open Graph automation.
WordPress site owners who have Smush installed for compression but need a separate plugin for image SEO — alt text generation, file renaming, and Open Graph metadata.
Smush compresses and lazy-loads images but has no alt text generation. This means millions of Smush users have fast-loading images that still can’t rank in Google Image Search. ImageSEO solves this.
Smush’s free tier doesn’t include WebP conversion — you need Smush Pro. ImageSEO doesn’t handle compression, but when paired with a compression tool, gives you the full stack for free at the SEO layer.
Like all compression plugins, Smush preserves original filenames. photo1.jpg stays photo1.jpg. ImageSEO renames files to keyword-rich descriptions that rank.
