SEO Enhancement (Optional)
Accessibility note: generated text is a starting point. Review each description for accuracy and tone before publishing. The tool provides checklists to help you validate the final copy.
How it works
Upload or paste imagery
Drag images into the workspace or paste directly from the clipboard. We support PNG, JPG, WebP, and SVG.
Add optional context
Paste the surrounding paragraph, page title, or product name so the AI understands how the image is used.
Review and export
Generate several variations, edit them in place, and export to CSV for CMS imports or accessibility audits.
Alt text best practices
Describe the essential content
Focus on the subject, action, and any critical details. Decorative imagery should use empty alt text so screen readers skip it.
Keep it concise
Aim for 125 characters or fewer. Longer descriptions can be placed in the caption or body copy.
Avoid repetition
Do not repeat phrases such as "Image of" or "Picture showing" unless the medium itself is important.
Frequently asked questions
Which AI model powers the generator?
We use Google Gemini 2.0 for multimodal understanding. The prompt includes your context plus accessibility guardrails curated by our content team.
Can I work in bulk?
Yes. Upload up to 25 images at a time, generate descriptions, and export everything to CSV or JSON for import into your CMS.
Is my data stored?
Images are sent securely to the Gemini API for processing and are not retained after the response. Generated descriptions are kept only in your browser unless you export them.
Does the tool handle multiple languages?
Provide context in the target language and select the language option before generating. We currently support English, Spanish, French, and German.
