AI birthday card and birthday photo prompts for Nano Banana
By GetStepSnap · Tested October 8, 2026
A card with their name on it, a birthday photoshoot, the moment the candles go out: Nano Banana 2.1 makes each from one prompt, with your photo or with words alone.
Every result below is the first one we got at 1K, resized and nothing else. The starting photos were made with the model.
Birthday photoshoot with number balloons
Use the woman in this photo and keep her face exactly the same. A birthday photoshoot: she sits on a pastel pink backdrop holding a bunch of pastel balloons, with large gold number balloons "3" and "0" beside her and confetti in the air. Bright, soft studio light, a cheerful portrait.
Gold "3" and "0" balloons, pastel balloons and confetti, as asked. Change the numbers to any age.
Blowing out the candles
Use the man in this photo and keep his face exactly the same. A candid birthday party photo: he leans in to blow out the candles on a chocolate cake while friends around the table cheer, with streamers and a few balloons behind him. Warm indoor light, a real party snapshot.
Friends cheering around the table, streamers and balloons, as asked; it also wrote a small "Happy Birthday" on the cake.
"Happy Birthday" cat card
Use the cat in this photo and keep it looking exactly like this cat. A birthday card: the cat wears a tiny striped party hat and sits next to a small cake with one candle, with confetti and a couple of balloons around it. Across the top, the words "Happy Birthday" in fun, bold letters. A bright, realistic photo.
"Happy Birthday" spelled right across the top; the party hat sits on the same orange tabby.
Dog's birthday with a bone-shaped cake
Use the dog in this photo and keep it looking exactly like this dog. A dog birthday photo: it wears a small party hat and a bandana and sits in front of a dog-friendly cake shaped like a bone, with balloons and a garland behind it. A bright, joyful, realistic photo.
Party hat, bone-shaped cake and garland, as asked. It added "Happy Birthday" to the bandana and the garland on its own.
Card with a name, no photo needed
A birthday card in loose watercolor: a bunch of colorful balloons and a few scattered stars on white paper, with the words "Happy Birthday, Sam!" hand-lettered in navy blue across the bottom. Plenty of white space, like a real painted card.
Made from the words alone, with the name spelled right. Swap "Sam" for any name.
Tips
- Put the words in quotes: the greeting, the name, the age on the balloons.
- Expect extra birthday touches. Ours added "Happy Birthday" to a cake, a bandana and a garland without being asked; say "no other text" if you don't want that.
- Choose 2K for printing. It still takes 1 credit.

Questions
Can AI make a birthday card with a name on it?
Yes. Put the greeting and the name in quotes, for example "Happy Birthday, Sam!", and say where it goes. Our watercolor card came back with the name spelled right, made from text alone.
Can I make a birthday photo from my own picture?
Yes. Attach the photo, start with "Use the woman in this photo and keep her face exactly the same" (or the man, cat or dog), and describe the party. Our number balloons, cake and party hats all came out as asked.
