AltTextLab

How to integrate AltTextLab with Webflow

AltTextLab connects to Webflow through three independent methods, each suited to a different workflow. The marketplace app generates alt text inside Webflow with no code required. The code embed runs on your published site, scanning for images without alt text and generating descriptions on page load.

Install the AltTextLab Webflow app

Install AltTextLab from the Webflow marketplace to generate alt text inside Webflow. Authenticate with your AltTextLab account, then generate descriptions for individual images or entire pages without leaving Webflow.

The marketplace app supports the following features.

• One-click generation: Select any image in Webflow and generate alt text with a single click
• Bulk page processing: Generate descriptions for all images on a page or across multiple pages in one pass
• Multi-language output: Generate descriptions in 130+ languages from your AltTextLab account settings
• Custom writing styles: Match descriptions to your content tone, including descriptive, neutral, matter-of-fact, and minimal options
• SEO keyword integration: Include target keywords in generated descriptions to support image search rankings

The app requires a Workspace or site plan that supports apps and editor access. Exact generation quotas depend on your AltTextLab plan. This is the fastest setup option and requires no custom code.

Add the AltTextLab code embed

The AltTextLab web snippet is a lightweight JavaScript tag that automatically scans images on your published Webflow site, detects images without alt text, and generates descriptions on page load. The script loads asynchronously, caches generated alt text on a global CDN, and serves cached results on subsequent visits to keep performance impact low.

The code embed provides the following capabilities.

• Automatic scanning: Detect and process images without alt text on page load, including images that load later as visitors scroll
• Image exclusion rules: Skip specific images using a CSS class (atlab-ignore) or data attribute (data-atlab-ignore), or exclude images below a size threshold
• Lazy-load compatibility: Handle dynamically loaded and responsive images without additional configuration

To implement the code embed, create a site configuration in your AltTextLab account dashboard and copy the JavaScript tag. For site-wide coverage, paste the snippet into your project's custom code in the head tag under Site settings > Custom code > Head code. For page-specific implementations, use a custom code embed element instead. After you publish, the snippet scans for images and automatically generates alt text.

This approach works well for sites with frequent image updates where manual alt text maintenance becomes impractical. The code embed requires a Webflow plan that includes access to custom code.

​​What You Can Build

Integrating AltTextLab with Webflow lets you automate alt text generation across design, e-commerce, and publishing workflows while supporting accessibility compliance and image SEO. Here are a few things you can build with this integration.

• Accessible portfolio sites: Generate descriptive alt text for design portfolios, photography sites, and creative agency showcases where visual content needs detailed descriptions for screen reader users
• E-commerce product catalogs: Create product image descriptions that incorporate brand names, model numbers, colors, and materials at scale for product pages built with Webflow CMS collection items
• Multi-language content hubs: Publish localized, image-heavy pages with automated alt text generation across 130+ languages so content teams can expand internationally without translating descriptions manually
• Marketing landing pages: Deploy campaign pages with hero images, product screenshots, and testimonial photos that include alt text with target keywords for improved image search rankings
