Alt Text Generator
Generate accessible, SEO-friendly alt text for your images from a file name or short description.
How the Alt Text Generator Works
Alt text (alternative text) describes an image for screen readers and for search engines, since neither can “see” a picture the way a person can. Good alt text improves accessibility for visually impaired visitors and helps your images appear in Google Image Search.
How this tool builds suggestions
Enter the image’s file name (or a short description) and, optionally, a target keyword. The tool cleans up the file name into readable words and combines it with your keyword using natural phrasing, then checks the length of each suggestion against the roughly 125-character guideline most screen readers handle well.
Alt text best practices
- Describe what is actually in the image, specifically and concisely.
- Keep it under about 125 characters so screen readers read it in full.
- Include your target keyword only if it genuinely describes the image, never force it in.
- Do not start with “image of” or “picture of”, screen readers already announce it as an image.
- For purely decorative images, use an empty alt attribute (alt=””) so screen readers skip over them.
