AI Images lets you generate images from text prompts and edit them with a suite of AI-powered tools. Generate from scratch, refine existing images, remove or replace backgrounds, upscale resolution up to 4x, detect and edit text inside images, and make precise region-level edits by marking areas on the image. All images live on the AI Canvas, an infinite workspace where you can arrange, compare, and continue editing.Documentation Index

What you can do
Generate from text
Describe what you want and the agent creates one or more images.
Remove Background
Strip the background from any image, leaving the subject on transparency.
Replace Background
Swap the existing background for a new AI-generated scene.
Upscale Resolution
Increase the resolution of any image by up to 4x while keeping detail.
Edit Text in Images
Detect text in any image and change the wording while preserving style.
Mark & Edit
Draw rectangles on specific areas and describe the changes you want.
Virtual try-on
Virtual try-on
Upload a garment image and a person image. The AI applies the clothing to the person, creating a realistic virtual try-on. Useful for e-commerce product shots without a photoshoot.
Sketch to image
Sketch to image
Draw a rough sketch and the AI turns it into a polished image based on your description.
Style transfer with references
Style transfer with references
Provide reference images and the agent matches styles, color palettes, and compositions from them.
Aspect ratios
Select an aspect ratio before generating.| Ratio | Description | Best for |
|---|---|---|
| 21:9 | Ultra-wide | Banners, cinematic scenes |
| 16:9 | Widescreen (default) | Presentations, thumbnails, social headers |
| 4:3 | Standard | Blog images, general use |
| 1:1 | Square | Social media posts, profile images |
| 3:4 | Portrait | Posters, product shots |
| 9:16 | Tall portrait | Stories, vertical social content |
| 9:21 | Ultra-tall | Vertical banners, phone wallpapers |
Not all models support all aspect ratios. The agent selects a compatible model automatically based on the ratio you choose.
Two ways to work with images
Through the chat
Describe what you want in the input bar. The agent generates or edits images and places them on the canvas. Best for creating new images, complex edits, and multi-step creative work.Directly on the canvas
Select an image on the canvas and use the toolbar (Remove BG, Replace BG, Upscale, Text Edit, Mark Edit, Edit Image) without going through the agent. Best for quick, targeted edits.Non-destructive editing
Every edit operation (background removal, upscale, text edit, mark edit, refine) creates a new image on the canvas rather than overwriting the original. Your original is always preserved. This gives you a built-in version history of every edit.What AI Images does not support
- Vector output (SVG). All images are raster format (PNG).
- Batch editing across multiple images at once from the canvas tools. Each image is edited individually.
- Animated images or GIFs. For motion, see AI Videos.
