Frequently Asked Questions
What is alt text?
The text description of an image in HTML (the alt attribute). Screen readers read it aloud, search engines use it to understand the image, and it shows if the image fails to load.
How long should alt text be?
About 125 characters or less is a good guide. Describe the image briefly and specifically — do not stuff keywords.
Can this tool see my image?
No. It writes drafts from the filename and description you type. You must check each suggestion against the real image.
Is my text uploaded anywhere?
No. Everything runs in your browser.
