Check one Shopify page for missing alt text.
Enter a public storefront page URL to see how many images are missing the behind-the-scenes alt-text field. Your results appear on this page.
Catalog gaps are easier to fix when you can see them
Shopify catalogs change constantly. New product images and rushed launches can leave missing alt attributes across the storefront. This checker looks only at the one public page you submit.
Lumi gives you a clearer starting point before your team spends hours editing product fields manually:
The installed app identifies catalog-wide missing product-image alt text, creates reviewable drafts, and records completed alt-text fixes.
Why updating your Shopify product data matters
Overlay widgets do not update product data.
The Widget Trap
Overlay widgets may change the storefront experience, but they do not rewrite product image alt text, SEO titles, meta descriptions, or product descriptions in your Shopify catalog.
- Does not fix source code
- Does not improve product search details
- Adds another storefront dependency
Updates inside Shopify
Lumi saves approved alt text to your Shopify product image fields, so the improvement remains part of your product data.
- Written to product data
- Updates saved to Shopify
- Review before publishing
Alt text workflows that match your plan
Free plan
Create image alt text and product content, review changes before publishing, and work with up to 10 products at a time.
Starter, Growth, and Scale
Generate all four content types with brand guidance and one selected language from 17 options. Growth and Scale also add optional auto-apply for selected content and weekly store scans.
Accessibility rules are broader than alt text
ADA, WCAG, and EAA accessibility work can involve your full storefront: navigation, forms, media, checkout, theme code, and product content. Alt text is one high-volume field Lumi can help you improve.
Lumi finds missing product-image alt text, keeps fixes reviewable, and records completed alt-text remediation. Manual accessibility review is still required.
What this single-page check shows
One submitted page
Checks the page returned for the storefront URL you enter.

Counts images that load from a usable address on that page.
Images without alt text
Flags images that do not include the HTML field used for alt text.
On-page results
Shows the count in your browser; it does not email a saved report.
