Frequently Asked Questions
Is empty alt text always bad?
No. Decorative images can use empty alt text. Important content images should usually have useful descriptive alt text.
Does this inspect image files?
No. It only checks the img tags in pasted HTML. It does not download or analyze the image files.
Can it generate alt text automatically?
No. It helps you find missing or weak alt attributes, but you should write accurate alt text based on the actual image and page context.
