Free AI Passport Photos in 5 Minutes with Nano Banana

Saturday hack: I turned a random 1-inch selfie into a studio-grade passport photo without leaving my desk—and spent exactly $0.00. Here’s the step-by-step so you can do the same before Monday.

What is “Nano Banana”?

In late-August 2025 Google dropped Gemini 2.5 Flash Image, nick-named Nano Banana by the community. It generates or edits any image in 1–2 seconds from plain English, keeps faces identical across rounds, and—best part—runs inside a free browser tab.

The 4-Minute Workflow

We wrapped the model into a no-code canvas called AI Image Editor. Point, type, download—done.

Step 1 – Log in

Open www.1bit.ai/services/ai-image-editor and click “Sign in” (Google or e-mail, no credit card).

Step 2 – Upload & prompt

• Upload a front-facing photo ≥ 720 px; glasses are fine, heavy shadows are not.
• Write a specific prompt (see copy-and-paste examples below). The more details—lighting, clothing, background—the less trial-and-error.

Step 3 – Choose ratio & model

Pick “3 : 4” for standard passport or “1 : 1” for CV head-shot, then select Nano Banana (fastest) or Pro (max detail).

Step 4 – Generate & refine

Hit Create. In 3–10 s you’ll see 4–8 variants. Click Edit on any to tweak brightness, smile, tie color, etc.—no re-upload needed. When happy, tap Download at 300 dpi, ready for printing or online forms.

Prompt Cheat-Sheet

Pro tip: end every prompt with “generate 8 options” so you can cherry-pick the best.

Female head-shot (U.S. executive style)

Convert the uploaded portrait into an American-style professional headshot, keep original face and identity intact. Half-body framing, blue textured studio backdrop, soft natural key lighting, ultra-sharp 4 K. Subject wears a sleeveless black midi dress, smooth fabric, no patterns, minimal gold jewelry. Relaxed confident expression, gentle smile, eyes in focus, background slightly blurred.

Male head-shot (business formal)

Transform photo into a business avatar, preserve facial features. Half-length, blue gradient background, indoor softbox lighting. White shirt, black suit, light grey tie, natural confident smile, crisp depth-of-field, clean professional look.

Bonus Hacks

• Interior mock-ups: “Scandinavian living room, mid-century furniture, morning light.”
• Fashion preview: “Put me in a navy trench coat, Paris street, overcast.”
• 3-D figurine: “Full-body chibi style, pastel colors, white background.”

That’s it—your AI passport studio is open 24/7 and never charges a dime. Go make your next profile picture the best one yet.
