Why use Image Upscaler?

Everything you need for fast, browser-based image upscaler — without a desktop plugin stack.

Sharper than a basic resize

Edge-aware super-resolution reconstructs detail instead of stretching pixels — better for products, faces, and line art.

Three upscale modes

2× and 4× Real-ESRGAN for fast pixel enlargement, or NanoBanana Pro for 4K creative upscale when you want more control over fine detail.

NanoBanana Pro with a prompt

Add optional guidance — sharpen labels, restore grain, keep skin natural — and Pro uses your source image as reference for a 4K result.

Portrait-friendly 2× / 4×

2× and 4× modes include optional face enhancement so headshots look cleaner without a separate retouch pass.

Browser-based studio

No desktop plugin or batch script — upload, run, and download from the same workbench as your other Gen NanoBanana tools.

Pay per finished image

Credits apply when you receive a successful upscale, so you only pay for outputs you keep.

Simple credit pricing

6–202 credits per image depending on resolution. Buy credit packs or subscribe on the pricing page — pack credits are valid for 1 year from purchase.

Workflow

How it works

Upload, run the tool in the studio above, and download — 3 steps for image upscaler.

  1. 01

    Upload your source image

    Drag a JPG, PNG, or WebP. For 2× / 4× super-resolution, keeping the long edge at or below 1440p tends to give the best speed and quality.

  2. 02

    Choose mode and options

    Select 2×, 4×, or NanoBanana Pro upscale. Toggle face enhancement on portrait runs, or add an optional prompt on Pro to steer 4K detail — leave the prompt blank for default guidance.

  3. 03

    Download the enhanced file

    Preview the before/after in the studio, then save the result for web, print, or marketplace listings.

Frequently asked questions

How does the AI image upscaler work?

Upload an image and pick a mode. 2× and 4× use edge-aware super-resolution to enlarge pixels with sharper edges. NanoBanana Pro upscale uses your image as reference and rebuilds it at 4K with optional prompt guidance for creative detail control.

What is NanoBanana Pro upscale?

NanoBanana Pro upscale uses our Pro image model at 4K with your upload as reference. You can leave the prompt blank for default upscale guidance or add a short note (e.g. sharpen packaging text, keep film grain). It costs more credits than 2× / 4× but suits premium assets and picky detail work.

What is the maximum input resolution?

For 2× and 4× super-resolution, keep the long edge at or below 1440p for stable quality and speed. NanoBanana Pro accepts larger sources but longer runs are normal for 4K output.

How many credits does upscaling cost?

2× upscale uses 6 credits per image; 4× uses 11. NanoBanana Pro upscale uses 202 credits (4K). See the pricing page for credit packs and plans.

Can I use upscaled images commercially?

Paid Gen NanoBanana plans include commercial licensing for outputs you create in the product. Check your plan summary at checkout for the exact terms.

Does upscaling invent new details?

AI upscaling predicts missing detail at higher resolution. 2× / 4× modes stay close to the source; NanoBanana Pro can follow your prompt more creatively. Neither mode can recover information that was never in the file — avoid expecting miracles on extreme blur.
