Nano Banana 2 on VeilPix: 15 Native Aspect Ratios Built In!

Nano Banana 2 (powered by Google Gemini 3.1 Flash) is the latest evolution of the model that revolutionized AI image editing. When the original Nano Banana first launched, one of its biggest challenges was creating different aspect ratios. VeilPix pioneered the transparent-image workaround to solve this. Now, Nano Banana 2 on VeilPix supports 15 native aspect ratios out of the box -- no workarounds needed! Whether you need desktop backgrounds, website banners, YouTube thumbnails, Instagram posts, or presentations, just pick your ratio and generate.

🔧 For Users of Other Platforms

Not using VeilPix? No problem! If you're using direct Gemini access or other AI image platforms that lack native aspect ratio support, you can still achieve aspect ratio control with the transparent image technique below.

This workaround is perfect for platforms that haven't yet implemented native aspect ratio support. The technique works with older Nano Banana (Gemini 2.5 Flash) and many other AI image models.

💡 The Manual Solution (For Other Platforms)

The technique involves providing Gemini with a blank, transparent image that already has your desired aspect ratio. Gemini uses this "reference" image to guide its output, ensuring perfect dimensions every time.

Step 1: Create Your Blank Transparent Image

🎯 What You Need

You'll need a blank transparent PNG file with the exact aspect ratio you want. Instead of using complex software like Photoshop, you can create a simple web-based tool using Gemini itself, or use the pre-made templates we provide below.

This works with any AI image editor, including VeilPix's privacy-first image generation and direct Gemini access.

Option 1: Create Your Own Tool

1

Go to Gemini AI

Open Gemini and initiate a new conversation.

2

Request the Tool Creation

Use this prompt to instruct Gemini to create a web-based tool:

"Create a minimalist web-based tool for generating transparent PNG files with user-specified aspect ratios. Include common presets like 1:1, 4:3, 16:9, and allow custom dimensions."
3

Generate & Download

Once the tool is generated, select your desired aspect ratio and download the transparent PNG file.

Option 2: Use Our Free Templates

Skip the tool creation! We've prepared common aspect ratio transparent images, tested with VeilPix and other AI image generators:

Landscape Ratios:

  • • 16:9 (Widescreen) - YouTube thumbnails, presentations
  • • 4:3 (Standard) - Classic photos, traditional displays
  • • 21:9 (Ultrawide) - Cinematic, banner images
  • • 3:2 (Photography) - DSLR standard format

Portrait & Square:

  • • 1:1 (Square) - Instagram posts, profile pictures
  • • 9:16 (Vertical) - Instagram Stories, TikTok
  • • 3:4 (Portrait) - Vertical photos, posters
  • • 2:3 (Classic) - Traditional portrait format

Step 2: Use the Blank Image for New Image Creation

This technique works with any AI image platform that supports image-to-image editing. We'll demonstrate using VeilPix, but the steps are identical for direct Gemini access and other tools.

1

Upload Your Reference First

Upload the blank transparent PNG you created before writing your main prompt. In VeilPix, simply drag and drop it into the image area.

2

Write Your Creative Prompt

Add your detailed image creation prompt. For example:

"A photorealistic picture of a frog riding a train in the 1950s"
3

Add the Magic Instruction

Include this crucial instruction at the end of your prompt:

"Use the uploaded image as the reference for final aspect ratio."
4

Generate & Enjoy!

Hit generate! Whether you're using VeilPix or another platform, Gemini will now produce images that match your reference aspect ratio.

💡 Pro Tip for VeilPix Users

VeilPix's privacy-first approach means your transparent reference images never leave your device until generation, providing extra security for your creative workflow.

The order matters! Always upload your transparent reference image first, then add your creative prompt with the aspect ratio instruction.

Step 3: Use the Blank Image for Editing Existing Images

This technique also works brilliantly for editing existing pictures while controlling the output aspect ratio! Perfect for when you want to expand a portrait into a landscape format, or vice versa.

1

Upload Your Original Image

Start by uploading the picture you want to edit to your AI image editor. In VeilPix, this protects your original image with local processing.

2

Add Your Transparent Reference

Upload your blank transparent PNG file as the second image. The platform will understand this as a dimensional guide.

3

Write Your Editing Prompt

Add your editing instructions. For example:

"Make the cat wear a red hat. Use the second image as aspect ratio reference."
4

Magic Happens!

Gemini will intelligently expand or crop the image to fit the aspect ratio of your transparent reference, filling in any new areas naturally while preserving the original subject.

⚠️ Important Note

For editing, the upload order can be flexible, but always specify which image serves as the aspect ratio reference in your prompt for best results. This ensures consistent behavior across different platforms.
