What does the Image Alt Text Helper do?

Alt text describes an image for people using screen readers and for search engines. Part one of this tool lists every <img> in pasted HTML and flags missing alt attributes, empty alts, alts that look like file names (“IMG_2041.JPG”), alts starting with “image of”, and alts that are too long.

Part two helps you write alt text based on the image’s role: informative images describe what matters, linked images describe the destination, images of text repeat the text, and purely decorative images get an empty alt="" so screen readers skip them.

How to use the Image Alt Text Helper

  1. Paste HTML containing your images to see the audit table.
  2. For each problem image, describe what it shows and why it is there.
  3. Choose its role (informative, link, decorative or text).
  4. Copy the suggested alt text into your HTML or CMS.

Examples

File-name alt

alt="DSC_0042.jpg" → “Chef plating biryani in a restaurant kitchen”.

Decorative divider

A purely decorative swirl should use alt="".

Limitations to know

Frequently asked questions

How long should alt text be?

Usually one short sentence — under about 125 characters. Put longer explanations in a caption.

Should I add keywords to alt text?

Only when they genuinely describe the image. Keyword-stuffed alt text hurts accessibility.

When should alt be empty?

For decorative images that add no information, so screen readers skip them.
