Nano Banana Pro FAQs

How many credits are needed to generate an image at each resolution tier?

Each Nano Banana Pro plan uses a credit system that is mapped to the chosen resolution.
Standard (up to 2K) images cost 4 credits each, Z‑Image (low‑noise stylized art) costs 2 credits, Pro 1K/2K images consume 8‑10 credits, and Pro 4K images consume 10‑12 credits. These values are reflected both in the subscription plan details and the “credits per image” pricing grid included on the pricing page.

What happens to the free credits that new users receive?

New users are granted 8 free credits upon account creation. These credits expire after 30 days of inactivity and can only be used for the same image generation or editing features available to the user’s chosen plan. After the period, the credits are automatically removed and must be replenished via a credit pack or subscription.

What is the main difference between Nano Banana Pro and Nano Banana Flash?

Nano Banana Flash is a lightweight, complimentary version that limits the resolution range to 1K or lower and provides a smaller set of prompts and editing tools. Nano Banana Pro, powered by Gemini 3 Pro image preview, offers full 4K‑resolution output, advanced character consistency, multi‑step error correction, and the additional Image‑to‑Image editing via Nano Banana Edit. The Pro tier also supports a broader set of aspect ratios and delivers faster generation times.

Does the Image‑to‑Image feature allow larger source files than 10 MB?

The current constraints for Image‑to‑Image uploads are set at a maximum of 10 MB per file, supporting JPEG, PNG, and WebP formats. Images larger than this limit will be rejected with an error; users should resize or compress images before uploading to meet the specification.

Are there any referral or promotional credits available?

The website does not advertise a referral program or automatic promotional credit allotments. Credits are only provided through the initial free‑credit bonus for new accounts or by purchasing credit packs and subscription plans. Any future promotional offers would be announced through the official blog or newsletters on the Nano Banana Pro site.
