13 Best Free Online AI Image Upscaler Websites

Here is a list of the best free online AI image upscaler websites. Upscaling means increasing the resolution of an image. This is done by adding more pixels to the image using AI. The technique of unscaling an image exponentially increases the pixel count by 2, 3, 4, 8, or even 16 fold. Increasing the resolution of an image makes it sharper and high quality. This also brings endurance for pixelization when zooming in or cropping.

In this post, I cover 13 websites where you can upscale your images for free. The process is straightforward. All you have to do is upload your image and apply an unscaling option of your choice. Some of these Websites offer unlimited upscales whereas some put on monthly or weekly limits. If you are dealing with an image format other than JPG or PNG then you have to check out for supported formats as well. I put all these important parameters of these Websites in bullet points. So you can just go through the post to check them out and find a website that can fulfill your needs.

My Favorite AI Image Upscaler Website

ImgUpscaler is my favorite AI image upscaler website on this list. The reason for it being my favorite is the allowed file size. You can find other websites that offer unlimited upscales but are limited in terms of size. Whereas this one can process an image up to 5 MB in size or 4000×4000 px in dimensions. It scales the images by 4x offering 10 free upscales per month.
