What is this AI blog image generator?
This free AI blog image generator turns a handful of keywords into a polished, ready-to-publish featured image — the perfect size for blog covers and social sharing (Open Graph / OG images). It uses Google's Gemini and Imagen models to create original artwork, so you don't need design skills, stock photos, or Photoshop to get a professional-looking blog image.
How it works
- Enter a few keywords that describe your blog post or topic.
- Pick a model — Imagen 4 or Gemini Flash — and generate.
- Crop the AI-generated image to 1200×630 and download it as a web-ready WebP file.
