Generador de texturas AI gratuito

Upscale Nano Banana and Nano Banana Pro images to 4K in under 15 seconds. No prompts needed.
Nano Banana is Google's Gemini image model family. MyArchitectAI is not affiliated with, endorsed by, or connected to Google in any way. This AI-powered tool upscales images created with Nano Banana, Nano Banana Pro, or any other AI image generator.

How to upscale Nano Banana images

01

Upload your image

Drag in a JPG, PNG, or WebP file, or click to browse. There are sample renders if you just want to test it. No account needed.
02

Pick the upscale factor

2x doubles each dimension, which covers most screen and presentation use. 4x takes a 1024px Nano Banana image output to 4096px, enough for print. No prompts needed.
03

Download the result

It takes about 15 seconds to upscale your image. Compare before and after with the slider, then download the full-resolution file. The first one is free, no signup.

Cómo usar el generador de texturas de IA

Nano Banana Pro can generate at 2K or 4K natively, but only on paid Gemini plans. If you work with standard Nano Banana outputs, or generated images before upgrading, those files sit near 1K. An upscaler rebuilds the detail that never got captured at generation time instead of stretching the pixels you have.

Renders are a special case. Hard edges and glazing reflections are exactly what smears at low resolution, and simple bicubic interpolation can’t bring them back.

SketchUp model

Adds detail instead of stretching pixels

The AI upscaler model was trained on of low- and high-resolution images, so it fills in texture and edge detail rather than averaging neighboring pixels. You can see the difference in things like grout lines and wood grain, which stay crisp instead of blurring out.
MyArchitectAI app interface

Generates a style-faithful output

The upscaler sharpens what’s already there without repainting anything. Color and composition stay put. Your image comes back as a cleaner version of itself. For edits, check Nano Banana prompts.
AI rendered image

Optimized for architecture and interior design

MyArchitectAI's upscaler handles renders from SketchUp, Lumion, Enscape, and Twinmotion, plus anything straight out of Gemini. Hard geometry and linework stay intact instead of getting the “oil painting” softening that general-purpose upscalers apply.

What people use it for

Most Nano Banana users who end up here fall into one of these situations.

Client presentations and pitch decks

A 1024px image looks soft on a 4K screen or when projected in a boardroom. Upscaling before you export the PDF means the renders hold up where it matters.

Print portfolios and brochures

A4 print at 300 DPI needs roughly 2480 × 3508px. A 1024px image printed that large looks pixelated. 4x upscaling closes that gap without a reshoot.

Real estate listings

Property portals penalize low-resolution photos in their ranking. An upscaled interior or exterior render reads better than the same image at 1K, especially on listing detail pages.

Competition boards

Architecture competitions usually specify minimum image sizes. If your Nano Banana renders came out at 1K, upscaling to 4K before compositing into the board avoids quality mismatches.

Social media and editorial

Instagram, Behance, and design publications prefer images at 2048px or wider. Upscaling your Nano Banana output means it fills the frame instead of getting centered with white bars.

Pre-press and signage

Banners and site hoardings print at low DPI but at very large sizes, so the pixel count still needs to be high. 4x from 1K covers most mid-size signage.

Frequently asked questions

Can Nano Banana upscale images?
Neither Nano Banana, Nano Banana Pro, nor Nano Banana 2 are dedicated upscalers but generative image models. While they can upscae your images, they'l add a watermark to your image, unless you're accessing them through the API/AI Studio.
What's the difference between upscaler and enhancer?
An upscaler adds pixels: it takes a 1024px image to 2048 or 4096px. An enhancer keeps the size and improves what's there: sharpening, color, compression artifacts. If your Nano Banana image is already big enough but looks soft, you need an AI enhancer instead. If it's too small for print, you're on the right page.
Why are my Nano Banana images blurry?
The blurriness can be caused when viewing a compressed chat preview, or because Nano Banana's upscaling process failed. Running it through a third-party upscaler is the most reliable way to fix it.
Is this the official Nano Banana upscaler?
No. This tool is made by MyArchitectAI and has no connection to Google. Google doesn’t sell an official Nano Banana upscaler at all. Ours works on images from Nano Banana, Nano Banana Pro, or any other generator.
Is it really free?
Your first upscale is free, full-resolution download included, with no account. Both 2x and 4x are available on that first use. After that you need a subscription. Most tools in this category make you sign up for credits before you see anything; here you can test the quality on your own image first.
What resolution can Nano Banana Pro images be upscaled to?
Nano Banana Pro can generate 2K and 4K natively on paid Gemini plans, so if you already have a 4K file there’s little to gain. The tool is most useful for standrd Nano Banana outputs (around 1024–1200px) and for Pro outputs that came out at 2K. The 4x option takes a 1024px image to 4096px, enough for A2 print at reasonable DPI.
What formats and file sizes are supported?
JPG, PNG, or WebP, up to 10 MB. The output comes back as a full-resolution PNG. If you need a smaller JPEG for the web, convert the PNG with any image editor.
How long does the upscaling process take?
About 15 seconds for most images, up to 30 seconds for larger files or at peak times. It runs in the cloud, so your own hardware doesn’t matter.
Can I use upscaled images commercially?
From our side, yes. We claim no rights to anything you upload or download. Rights to the underlying AI-generated content depend on where you generated it, so check Google’s Gemini terms for their current stance.
Does it work on renders from SketchUp, Revit, or Lumion?
Yes. It handles renders exported from SketchUp, Revit, Lumion, Enscape, or Twinmotion, plus Midjourney and Stable Diffusion outputs. The page name aside, it isn’t limited to Nano Banana images. Renders are actually one of the better use cases because hard geometry and glazing survive the process instead of getting softened.
Can Nano Banana upscale videos?
No, Nano Banana is only an image generation model, and doesn't handle videos. For generating and editing videos, you can use Google's other model, Gemini Omni Flash.
