Nano Banana 2.1 AI Image Generator
Nano Banana 2.1 turns a text prompt into a JPG or PNG. Add up to 14 reference photos when the picture should follow a person, product, or layout. This page generates at 1K for 4 credits. Open the studio for 2K at 6 credits or 4K at 9 credits, and to switch the file between JPG and PNG.
What you control before you generate
The choices on this page change the frame, the references, and the credit quote.
Pick the frame before you write the prompt
Square 1:1 suits a product tile. 16:9 and 21:9 suit a banner. 9:16 suits a phone story. 4:1 and 1:8 are extreme strips, not a normal photo crop.
Add references only when the picture must follow them
You can attach up to 14 PNG, JPEG, or WebP files, 5 MB each. Skip them for a fresh scene. Add them when a face, product, or layout has to stay recognizable.
See the 1K price before you run
The generator on this page quotes 4 credits, the 1K price. 2K is 6 credits and 4K is 9 credits, chosen in the studio, not in this short form.
Choose JPG or PNG in the studio
If you do not pick a format, the result is JPG. PNG is available in Advanced settings, alongside the resolution switch.
How to generate an image with Nano Banana 2.1
Three decisions that change the file you download.
Choose an aspect ratio that matches the placement
Use 1:1 for a catalog tile, 3:4 or 4:5 for a portrait, 16:9 for a web banner, and 9:16 for a vertical story. The full list also includes 2:3, 3:2, 4:3, 1:4, 4:1, 1:8, 8:1, and 21:9.
Attach references only for what must stay
Upload PNG, JPEG, or WebP, up to 5 MB and 14 images. In the studio, Auto appears once a reference is attached and follows that photo’s framing. A prompt with no image starts a new picture.
Write the prompt, then pick 1K, 2K, or 4K
A prompt is required and can be up to 20,000 characters. Generate here for a 1K JPG at 4 credits. Advanced settings opens the studio on Nano Banana 2.1 with the same prompt, where you set 2K, 4K, or PNG. Sign in to spend account credits.

When this model is the practical choice
Product tiles that must match a real item
Upload the packshot and ask for a new surface or background. The reference cap of 14 covers extra angles, not just one hero photo.
Portraits that keep a face
Attach a clear photo, name what may change, and name what must not: pose, glasses, or the room.
Banners with a known crop
Start from 16:9 or 21:9 so the file fits a header instead of being cropped after the fact.
A cheaper 1K draft before a 4K file
Run the 4-credit 1K pass on this page. If the framing is right, open Advanced settings and rerun at 4K for 9 credits.

Questions about the file you get
Which file type do I download?
JPG unless you switch to PNG in Advanced settings. Both are available for Nano Banana 2.1.
Why is the price on this page 4 credits?
This short generator stays on 1K. 2K and 4K are 6 and 9 credits, and you select them in the studio.
What if I attach more than 14 images?
The request is rejected. Remove images until you are at 14 or fewer.
Can I generate before I sign in?
No. The generator asks you to sign in, then spends credits from that account.
