Quick answer: ImageSEO is a WordPress plugin, so it works anywhere the WordPress Media Library works: posts and pages, WooCommerce product images, featured images, and gallery plugins such as NextGEN Gallery, Photo Gallery and FooGallery. It writes alt text, titles, captions and file names into WordPress’s own media fields, which SEO plugins like Yoast SEO and Rank Math read, and it runs alongside compression and caching plugins without overlapping them. It doesn’t work outside WordPress: there’s no Shopify, Wix, Squarespace or Contao version.

The compatibility list comes from the plugin’s description on WordPress.org and our plugin and theme compatibility page. If you run into a conflict with something not listed, email support@imageseo.io and tell us which plugin it is.
Everything ImageSEO does happens in the Media Library, which is why it works with most themes: it fills the standard WordPress fields rather than storing text somewhere of its own. There are three ways to use it:
The language of the generated text follows your site’s language by default, and you can change it in the settings. Titles and captions can be filled as well as alt text.
WooCommerce stores product photos, product gallery images and featured images in the normal Media Library, so ImageSEO treats them like any other image. That matters for stores: product photos are often uploaded in batches straight from a camera or supplier with names like DSC_0421.jpg and no alt text. Running the bulk optimizer once gives every product image a description and a readable file name; after that, new uploads are handled automatically. More on this on our image SEO for WooCommerce page.
Most gallery plugins display images from the Media Library, so the alt text ImageSEO writes shows up in the gallery automatically. NextGEN Gallery is different: it keeps its own image storage, and ImageSEO has dedicated support for it, including renaming NextGEN files. Photo Gallery, Responsive Photo Gallery and FooGallery are listed as compatible in the plugin description.
Alt text works with every page builder, because it’s stored with the image. File renaming is more delicate. Some builders save image URLs inside their own encoded layout data, where a plain search-and-replace can’t reach them, so renaming a file could leave a broken image on the page. For that reason ImageSEO switches off renaming when it detects Divi, Beaver Builder or Visual Composer. Elementor isn’t on that list, but the same caution applies: rename a few test images first and look at the pages that use them, especially images used as section backgrounds.
If you want renaming anyway, add this line to your child theme’s functions.php or a code snippets plugin:
add_filter( 'imageseo_authorize_page_builder', '__return_true' );
Try it on a staging copy or a handful of images first, then check the pages that use them. The full explanation is in how to unlock file renaming for a page builder.
SEO plugins and ImageSEO do different jobs. Yoast SEO, Rank Math and SEOPress handle titles, meta descriptions, sitemaps and schema, and their content analysis checks whether the images on a page have alt text. None of them looks at an image and describes it. ImageSEO fills in that alt text, so the check your SEO plugin runs has something real to find.
One setting worth knowing about: Rank Math can add missing alt attributes automatically, built from a template such as the file name. That only applies to images that still have no alt text. Once ImageSEO has written a description, that description is what visitors, screen readers and search engines get.
Smush, Imagify, EWWW, Optimole, TinyPNG and WP Rocket make images smaller or deliver them faster. ImageSEO doesn’t compress, convert or cache anything, so they don’t get in each other’s way: one makes the file light, the other says what’s in it. The one thing to avoid is two tools writing alt text. ShortPixel, for example, can also generate AI alt text, so pick one to be in charge. Our comparison pages go through each of these plugins in detail.
ImageSEO can generate social preview cards for posts and pages using the Open Graph protocol, so a shared link on Facebook, LinkedIn or X shows a proper card instead of a random image. See how Open Graph social cards work.
For Pinterest, the plugin adds four fields to every image in the Media Library: Pinterest description, URL, ID and media. They control what people see when they pin your image. Here’s how to change Pinterest attributes in WordPress.
ImageSEO only runs on WordPress. There’s no app for Shopify, Wix, Squarespace, Webflow, Contao or TYPO3, and we’d rather say so than send you to a sign-up that won’t work for your site. If you only need a description for a few images, the free alt text generator works in the browser for any platform: upload an image, copy the text and paste it into your CMS.
There’s no promo code published on imageseo.io. There are three honest ways to pay less:
Every paid plan comes with a 14-day money-back guarantee. All plans and limits are on the pricing page.
Yes. Alt text, titles and captions work as on any WordPress site. File renaming isn’t switched off for Elementor, but rename a few test images first and check the pages that use them before renaming in bulk.
No. They’re listed as compatible in our documentation. ImageSEO writes the image text; your SEO plugin handles the rest of the page.
Yes, depending on the plan. Free, Starter and Standard cover one project, Premium covers 10 and Enterprise is unlimited. See on how many sites you can use ImageSEO.
The image analysis runs on ImageSEO’s servers, not on your hosting, and bulk jobs are processed in the background. Visitors don’t load anything extra: the result is plain text in your existing image fields.
No. ImageSEO is a WordPress plugin only. For a few images on another platform, use the free alt text generator and paste the result into your CMS.
