Live feedback

  • Alt text is empty. Describe what the image shows, or mark it decorative if it adds no information.

Alt text rules of thumb

  • Describe the image's purpose, not every pixel: what would a reader miss if the image vanished?
  • Never start with "image of" - screen readers announce the element type already.
  • Keep it under 125 characters; most screen readers truncate long alt text.
  • Do not stuff keywords - alt text is for people using assistive tech, not rankings.
  • Pure decoration (borders, spacers, background flourishes) gets alt="" so it is skipped.
  • Charts and infographics need a longer text alternative nearby, not just one line.

About this tool

IconVault's Alt Text Helper helps you write image alt text that actually works for screen reader users. Type your draft and get instant, specific feedback: whether the length sits in the 125-character sweet spot, whether it opens with redundant phrases like "image of" or "photo of", and whether it drifts into keyword stuffing. A decorative-image toggle guides you to the correct empty alt="" when the image adds no information.

It is free and runs fully in your browser, so your drafts never leave your device. The honest limit: these are heuristic checks, not AI image recognition, so the tool cannot see your image. Always read your alt text back against the actual picture and ask whether a listener would understand what matters in it.
