Alt text for this photo
- Short
- Longer
Check it before you use it: you know what matters on your page. Written by Claude, Anthropic's AI. Your photo is shrunk on your computer, read once to write this, and not kept.
Where to paste it
You get it two ways, short and long, each with its own Copy button.
- WordPress
Click the picture, and in the panel on the right, fill in Alternative text.
- Wix
Click the picture, then the Settings icon, and fill in What's in the image?
- Squarespace
Click the image block, then the pencil icon, and fill in Image alt text on the Content tab.
- Shopify
Open the product, click the photo, choose Add alt text, then Save alt text.
Alt text is one of the first things accessibility checks look for, and one of the most common gaps. Website accessibility: where to start, with the tools that help and what the law asks.
How to use it
- Choose a photo (or drop it on the box). Add what the page is about if you like: it helps.
- Wait a few seconds for the short and longer descriptions.
- Read them. Change anything that's wrong; you know what matters on your page.
- Press Copy and paste it into your website (see where below).
What your results mean
- Short
- For most pictures. One sentence a screen reader reads out in place of the picture.
- Longer
- For pictures that carry information, like a chart or a menu.
When to use it
- You're adding a photo and the alt text box is empty.
- Picture Check or Accessibility Check found pictures with no description.
- A chart, poster or menu is a picture, and you need to say what's in it.
Why it matters
- A screen reader reads alt text out in place of the picture. Without it, a blind visitor misses what the picture shows.
- Alt text also shows when a picture fails to load, and search engines read it to understand the picture.
