The Best ShortPixel Alternative for WordPress Image SEO

ShortPixel is excellent at image compression. But if you’re looking for an alternative because you need alt text generation, SEO file renaming, or Open Graph automation, ImageSEO is the plugin you’re missing. These are different tools that solve different problems — and your WordPress site likely needs both.

Who This Is For

WordPress site owners who have ShortPixel installed and are looking for a tool to handle the SEO side of image optimisation — alt text, file names, and metadata.

The 3 Image SEO Problems ImageSEO Solves

ShortPixel doesn’t generate alt text

ShortPixel compresses images brilliantly. But it does nothing for alt text. If your images have no alt text, they won’t rank in Google Image Search regardless of how well-compressed they are. ImageSEO fixes this with AI.

ShortPixel doesn’t rename files for SEO

ShortPixel preserves your original filenames. So IMG_4821.jpg stays IMG_4821.jpg. ImageSEO renames it to something like wordpress-image-seo-dashboard.jpg — a file name Google can actually understand.

ShortPixel doesn’t set Open Graph

ShortPixel handles file delivery, not metadata. Open Graph images — which control how your pages look when shared on social media — need a separate tool. ImageSEO handles this automatically.
