How AI alt text generation works
Powered by Google Gemini
SammaPix sends a thumbnail of your image to Google Gemini Flash which returns a concise, descriptive alt text optimized for both accessibility and SEO.
WCAG 2.1 compliant
Generated alt texts follow web accessibility guidelines- descriptive, meaningful, and appropriate length (50-125 characters) for screen readers.
SEO-optimized output
Alt text doubles as image SEO signal. Get descriptions that help your images rank in Google Image Search while serving accessibility requirements.
What is alt text and why does it matter?
Alt text (alternative text) is an HTML attribute added to image tags that describes the image for screen readers used by visually impaired users. It is also a key SEO signal - Google uses alt text to understand the content and context of images on your page.
What makes good alt text?
Good alt text is specific, concise, and describes the key visual content without starting with "image of" or "photo of". WCAG guidelines recommend 50-125 characters for most images. SammaPix AI generates alt texts that follow these conventions automatically.
