The Best Smush Alternative for WordPress Image SEO

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.

Who This Is For

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.

The 3 Image SEO Problems ImageSEO Solves

Smush has no alt text features

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 Free has no WebP without upgrade

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.

Smush doesn’t rename files

Like all compression plugins, Smush preserves original filenames. photo1.jpg stays photo1.jpg. ImageSEO renames files to keyword-rich descriptions that rank.
