Capabilities

Generate. Edit. Restyle.

One image model for fast creation and precise, reference-led editing — at any size, with text that reads.

Precise editing

Change the mood, shift day into night, explore a new camera angle or redirect focus while keeping the parts of the image that already work.

Reference style

Bring a texture, color language or visual style from a reference image into a new subject. Explore distinct aesthetics while preserving the creative idea underneath.

Multi-size output

Adapt a finished idea for the format where it will appear. Reframe the composition for landscape, square or portrait placements while keeping the details that matter.

Text rendering

Create logos, invitations, posters, comics and other text-led visuals with clearer lettering. Nano Banana 2 can place words inside the image in many languages.
