AI Image Upscaler: Upscale Images 2x, 4x, or 8x
Upload a photo and upscale it 2x, 4x, or 8x. Krea increases the resolution and redraws the detail the larger size needs, so the result stays sharp instead of stretched. Paid plans upscale to 4K and 8K.
Upscale to 4K and 8K
How large will your upscaled image be?
Each upscaling factor multiplies the width and height of your image. 4K UHD is 3840 × 2160 pixels and 8K is 7680 × 4320, so the factor you need depends on where you start. 4K and 8K output need a paid plan; free use is capped at 2048 pixels on the longest side.

Resizing an image in a photo editor only stretches the same pixels, so it stays soft on a large screen or print. The AI image upscaler redraws edges, textures, and fine detail at the new size, so it looks like it was made at that resolution.
Your aspect ratio doesn’t change. A square or portrait image keeps its framing and reaches a 4K-class width or height, ready for wallpapers, prints, and large displays.

AI image upscaler FAQ
An AI image upscaler increases the resolution of an image. Instead of stretching the existing pixels like a normal resize, it generates new detail, so the larger image looks sharper and clearer than traditional upscaling.
Upload your image, choose 2x, 4x, or 8x, and click Generate. When the upscaled version is ready, compare it with the original and download it.
Use 2x for quick quality improvements and web use, 4x for most prints, marketing assets, and 4K screens, and 8x when the source image is very small or you need a very large print. Hover over each option to see its exact output size.
