AI Alt Text Generator

Try AI Alt Text Generator to write SEO-friendly image alt text in one click. An alt tag generator and image describer for any site.

AI Alt Text Generator is a Chrome extension that writes alt text for any image you see on the web. Pick a picture on the page, right-click it, or capture any area of the screen, and a short, accurate description appears in the side panel, ready to paste into your website. 🖼️ Generate alt text in three steps 1. Open the side panel from the toolbar icon or the floating button. 2. Click "Pick an image", right-click a picture, or select an area of the screen. 3. Copy the alt text and paste it into your editor or CMS. An alt text generator for images on any page Most images that need alt text are already in front of you: in a media library, a product page draft, a blog post preview or a landing page. AI Alt Text Generator works right there, so you don't download files or switch to another site. It describes the main subject, the setting and the details that matter, in a sentence or two. The result appears under a preview of the picture, so you can check at a glance that the description fits. It handles the images people struggle to describe: • Product photos and lifestyle shots • Screenshots and interface images • Charts, graphs and diagrams, with the key takeaway • Banners, quotes and other images that are mostly text • Background images and pictures inside sliders When a picture can't be picked directly, draw a box around it. Area capture turns any part of the screen into a description, so even slides, embedded viewers and canvas graphics get alt text. Alt text for SEO and accessibility Good alt text helps two audiences at once. Screen readers read it aloud to people who can't see the image, and search engines use it to understand what your images show. The AI writes descriptive, natural sentences instead of keyword lists, which is what accessibility guidelines such as WCAG ask for and what image SEO rewards. Each description stays close to the recommended 125 characters, and the side panel shows the length as you edit. It skips filler like "image of" or "picture of", and it uses the page title to name things correctly. You can change any word before you copy, or regenerate for a different wording. Alt text in your language Alt text should match the language of the page. By default, the extension writes in the language of the website you are on. You can also choose from 40 languages, including Spanish, German, French, Portuguese, Japanese and Arabic, which helps teams that run multilingual stores and blogs. Switch the language and regenerate to get the same description for a translated version of the page. Frequently asked questions ➤ How do I write alt text for images quickly?
