Nano Banana — AI image generator

Edit an image by describing the change, and keep the character.

Nano Banana is Google's conversational image editor, and it solves a problem the generators do not. Ask an ordinary model for the same character in a new pose and you get a different person who dresses similarly. Ask Nano Banana to change the pose and you get the same face — identity survives the edit. That makes multi-panel work possible: a comic, a storyboard, a product in six settings, a mascot that is recognisably one mascot.

You drive it in plain language — "put him in a red jacket", "make it evening", "remove the car" — rather than by rewriting a prompt from scratch and hoping. Each instruction applies to what is already there.

What Nano Banana is good for

• The same character across many images
• Iterative retouching described in plain words
• Storyboards, comic panels, and product variants

Worth knowing before you spend credits

It has no pixel-size control at all — only a fixed list of aspect ratios, and an unsupported ratio is snapped to the nearest one it does support. If you need an exact pixel dimension, generate on Seedream or Flux and bring the result here to edit.

Questions

Can Nano Banana keep the same character across images?

Yes — that is its main strength. Identity holds across successive edits, which is what makes series work practical.

Can I set an exact width and height?

No. Nano Banana accepts only a fixed set of aspect ratios and has no pixel size field; anything else is snapped to the closest shape it supports.
