An AI image upscaler uses artificial intelligence to increase image resolution. AI image upscaling generates new pixel information, resulting in sharper, clearer images than traditional upscaling techniques.

Krea offers free AI image upscaling, so you can try the magic of AI without spending a cent. You can upscale and enhance several images per day at no charge, enough to experiment with different parameters.

Upscaling takes from a few seconds to a minute, depending on how the level of upscaling you requested, the model used, and our overall server load.

AI-powered upscaling is perfect for:

Graphic designers who need high-definition visuals for print and digital media
Businesses E-commerce polishing product photos for online stores
Photographers looking to improve resolution of their images
Anyone looking to increase the resolution of their images or restore photos with AI

AI upscaling can significantly improve moderately blurry or compressed images by reconstructing details and reducing artifacts. However, it cannot recover information that was never captured—extremely blurry, heavily pixelated, or motion-blurred images have fundamental limits. The AI makes intelligent guesses about missing details, which works well for minor quality issues but cannot perform magic on severely degraded sources. When there's a blurry face, for example, the AI will do its best to fill in the space with a realistic face, but there's no guarantee it will look like the person in the original photograph. The best results come from images that are small but relatively sharp.

Yes, you can queue multiple requests, whether that's for different images, or multiple enhancement requests of the same image, if you want to try alternative versions with different models or settings.

Yes! Users of any of our paid plans get commercial rights to use Krea outputs, so you can use them as you wish as long as you have the rights to use the original image commercially. (Images upscaled by free users are not licensed for commercial use.) Remember that other legal restrictions around AI use may apply in your jurisdiction, including personality rights, copyright, disclosure of AI user, and and other considerations.

Krea supports common image formats such as JPG, PNG, and WebP, so you can quickly upscale most photos, graphics, and AI images. For best results, upload the highest-quality source file you have.

Use 2x for fast quality improvements and smaller files, 4x for most print or marketing use cases, and 8x when you need very large outputs or aggressive detail recovery. If unsure, start with 4x and compare.

No. Upscaling keeps your original composition and aspect ratio while increasing pixel count and improving clarity. Your image framing stays the same, just at a higher resolution.

Yes. Krea works well with many visual types, including photos, digital art, illustrations, product graphics, and social assets. You can test different upscaling levels to find the best look for each style.
