Image Alt Text

Description

The “Image Alt Text” plugin is a simple yet powerful tool that allows website owners and content creators to easily edit the alt tags for images on their website. Alt tags, or alternative text descriptions, are important for both accessibility and search engine optimization (SEO) purposes, as they provide a textual description of an image for users who are visually impaired or for search engines that cannot interpret images.

With this plugin, website owner and admins can easily edit alt tags for all images on their website directly from the Plugin Menu. The plugin provides a user-friendly interface that allows users to quickly update alt tags for individual images or copy alt text for all missing images. Additionally, the plugin includes a feature to generate alt tags based on the image file name, saving users time and effort.

Buy Pro Image Alt Text

  1. 4 AI Vision Providers — Bring Your Own Key
    Generate highly accurate, SEO-friendly alt text using OpenAI GPT-4o, Google Gemini 2.0 Flash, Claude AI (Haiku), or Hugging Face (Qwen2.5-VL). Connect any provider with your own API key. Write a custom prompt tailored to your site’s tone and SEO goals. You pay the AI provider directly — no markups, no bundles.

  2. Auto-Generate Alt Text on Every Upload
    Set it and forget it. The moment an image is uploaded, alt text is generated automatically using your preferred method (OpenAI, Gemini, Claude, Hugging Face, Post Title, or Filename). No manual steps required.

  3. One-Shot Bulk Actions
    Process every image in your current view with a single click. No selection needed — just pick an action (Copy Title, Copy Filename, or any AI provider) and click Process. Configurable batch size controls how many images are sent to the AI API per request.

  4. Unlimited Bulk AI Selection
    Select any number of images in Bulk Action and run AI generation across all of them. Images are processed one at a time sequentially — no timeouts, no rate-limit errors regardless of selection size.

  5. Bulk Caption Actions
    Copy post titles or filenames to image captions in bulk. Also supports per-image caption update directly from the image list.

  6. Decorative Image Accessibility (WCAG 2.1)
    Mark any image as decorative in the media library. The plugin automatically injects role="presentation" and aria-hidden="true" on the frontend so screen readers skip the image entirely. Covers both Gutenberg image blocks and PHP-rendered images.

  7. SEO Quality Score for Every Image
    Every image in your library is rated Excellent, Good, or Needs Work based on alt text quality — so you can prioritise which images need attention first.

  8. Visually Spot Missing Alt Text on Your Live Site
    Enable a frontend highlight to outline images missing alt text directly on your published pages. Instantly see where the gaps are without digging through the media library.

  9. Advanced Date Range Filters
    Filter your image list by Today, Last 7 Days, Last 30 Days, Last 6 Months, Last 12 Months, Last 3 Years, or a custom range — ideal for large media libraries or audits.

  10. Central Settings Panel
    Sidebar-navigated settings page to configure AI providers, API keys, custom prompts, upload automation, batch size, and highlight preferences — all in one place.

After I uploaded alternative texts for over a hundred products, I realized I couldn’t keep doing it that way. Then I found this plugin, and with just one click, all the uploads were completed.
