Paste image URLs, one per line. AltCaption turns product photos, gallery images, and content libraries into ready-to-use image descriptions in one batch for accessibility and SEO.
Generate product image alt text from storefront, marketplace, supplier, or CDN image URLs.
Prepare alt tags before moving media libraries into Webflow, WordPress, Shopify, or a custom CMS.
Copy results as a table-friendly list so editors can review descriptions before launch.
Paste a list of image URLs and generate descriptions that can be reviewed, copied as a spreadsheet-friendly table, and added to product feeds, gallery records, or page templates. This is useful when missing alt attributes are spread across a catalog instead of one page.
AltCaption is tuned for concise, useful image descriptions rather than keyword stuffing. Use it to describe what is visible in each image, then edit any brand, product, or context details that only your team knows.
