Frequently Asked Questions

What is AI image enhancement?
AI image enhancement uses machine learning models trained on millions of images to intelligently improve photo quality. Unlike simple filters, AI understands the content of your image and can add realistic detail when upscaling, selectively reduce noise while preserving edges, and sharpen features without introducing artifacts.
How much can I upscale my image?
Nano Banana supports 2x and 4x upscaling. A 2x upscale doubles both the width and height of your image (resulting in 4 times the total pixels), while 4x quadruples each dimension (16 times the total pixels). For best results with very small images, consider running a 2x upscale first and then enhancing again.
What image formats are supported?
The AI Image Enhancer accepts JPG, PNG, and WebP uploads. Enhanced images are returned in PNG format to preserve maximum quality. There is no loss of color depth or transparency during processing.
Is there a file size limit?
You can upload images up to 10 MB in size. For optimal processing speed, images under 4000 x 4000 pixels are recommended. Larger images may take longer to process but will still produce high-quality results.
Will enhancement change the colors of my image?
No. The enhancement pipeline is designed to preserve color accuracy and tonal balance. Noise reduction and sharpening operate on luminance and edge data without shifting hues, saturation, or exposure.
How many credits does image enhancement cost?
Image enhancement costs vary by the upscale factor and options selected. Check the pricing page for the latest credit costs. New users receive 30 free credits on signup to try the platform.
