Accessibility checks
  • Informative image: use descriptive alt text because the image adds meaning to the page.
  • Length check: the recommended option is within the common 125-character screen reader guideline.
  • SEO check: keywords were used only as context. Remove any keyword that does not describe the image.
  • Visible text check: image text was included because screen readers cannot reliably read text embedded in images.

Decorative image guidance

Use alt="" only if this image is purely decorative and repeats nearby text.

How to write better alt text

  1. 1. Describe the image

    Enter the main subject, the visible details, and any text that appears in the image.

  2. 2. Set the page purpose

    Choose whether the image supports an article, product page, social post, newsletter, documentation page, or decorative layout.

  3. 3. Add optional SEO context

    Include one or two target keywords only when they naturally describe the image and page topic.

  4. 4. Copy the best option

    Review concise, SEO-aware, and detailed versions, then copy the one that best matches the image purpose.

Alt text FAQ

What is alt text?+

Alt text is a short text alternative that describes an image for people using screen readers and for cases where the image does not load. Good alt text explains the image's useful content in the context of the page, not every visual detail.

How long should alt text be?+

Most alt text should be under about 125 characters. That length is concise enough for screen readers while still leaving room to describe the subject, action, and page-relevant detail.

Should alt text include SEO keywords?+

Only include a keyword when it naturally describes the image. Keyword stuffing makes alt text worse for accessibility and can make the page look spammy. Accessibility should come first.

When should an image have empty alt text?+

Use empty alt text for decorative images that add no meaning, such as background patterns, divider graphics, or repeated icons next to visible labels. Informative images should have descriptive alt text.

Can this tool generate alt text from an uploaded image?+

No. This tool does not upload or inspect image files. It uses the image description and page context you enter, so nothing leaves your browser and you stay in control of the final wording.
