How to make AI-generated images
Go from idea to a delivered asset in three steps, with nothing to install.
- Describe it: write a prompt for the image you want, or drop in a photo to build on.
- Generate: get results in seconds and keep tweaking the prompt until it looks right.
- Optimize and deliver: Cloudinary formats, resizes, and serves the final image anywhere.
Any style, dialed in with a few words
Photoreal, illustrated, 3D, watercolor, line art, neon, retro: steer the look, mood, and composition right from your prompt. Keep one consistent style across a whole set, then generate in the exact aspect ratio and resolution each placement needs.
Generate once, deliver everywhere
The image you generate doesn’t just sit in a folder. It lands in Cloudinary, ready to resize, reformat, and serve through the same pipeline that already powers your site and apps. One asset becomes every crop, format, and size your channels need, delivered fast to every device.
