Image Alt Text Checker

Alt text describes an image in words. It helps screen reader users understand images, and it helps search engines understand what an image shows. Missing alt text is one of the most common and most fixable page issues.

This tool reads the HTML you paste and lists every image with its alt status. You can see at a glance which images need alt text and which are already fine.

How to Use This Tool

1. Paste your HTML: paste a full page or just the content section.
2. Click Check Images: read the list of images and their alt status.
3. Fix missing alt text: add short descriptive alt text to meaningful images.
4. Check again: paste the fixed HTML and confirm the missing count is zero, apart from purely decorative images.

Good Practice Tips

• Describe, do not stuff: write what the image shows in plain words, not a list of keywords.
• Decorative images may stay empty: a purely decorative image can keep an empty alt value, so screen readers skip it.
• Keep it short: one clear sentence is usually enough for alt text.
• Do not repeat nearby text: if the caption already says it, the alt text does not need to repeat it word for word.
