Your source for the best free Nano Banana prompts
NB Prompts is a free prompt library built for people using Google’s "Nano Banana: image model (Gemini image). It provides thousands of ready-to-paste prompts that produce consistent, high-quality results without wasting time on trial-and-error. No fluff, no fake "secret formulas", just prompts that work.
Each prompt is written to be practical and reusable. You’ll find clear structure, strong subject control, composition and lighting guidance, and output constraints that reduce common failures (weird faces, random objects, style drift, unwanted text). Many prompts also include optional “with reference upload” variants so you can keep identity consistent when you supply a face photo.
The library is designed for fast searching and quick copying. Browse by style (photoreal, cinematic, product, fashion, architecture), use-case (ads, thumbnails, profile pics, room redesign, character concepts), or format (single-line prompt, advanced prompt, JSON packs). Whether you’re generating one image or building content at scale, nbprompts.net is the go-to place to pick a prompt, paste it, and get results.
