Frequently asked questions
How long should alt text be?
Aim for under about 125 characters. Many screen readers handle short descriptions better, though there is no hard limit.
Should I stuff keywords into alt text?
No. Describe the image accurately. A keyword is fine when it genuinely describes the image.
Do I need to say an image is AI-generated?
It is good practice to be open about it, and some platforms require labels for realistic synthetic images. Check each platform’s current rules.
