Al image upscaler is the process of adjusting a digital image so that the result is more suitable for display. Upscale image means increasing the resolution of the image. The higher the resolution of the picture, the more pixels it contains, the better the quality of the picture, and the clearer the picture. Therefore, the essence of our enlarged picture is to improve the quality of the picture

Five ai image upscalers

The following five are all capable of enhancing low-resolution images, removing noise from photos. And adjusting color and exposure levels to improve the overall quality of an image. Next, I will introduce their characteristics, and attach their advantages and disadvantages, so that you can compare and choose.

1. Picwish

PiWish is an artificial intelligence-based photo editing platform that provides a variety of photo editing functions. It’s easy to use and optimizes images without complicated operations.

2.Smart Upscaler

Smart Upscaler uses AI technology to zoom in on images smoothly. It can enlarge the image by 2 times or 4 times, and use machine learning to automatically sharpen, reduce noise and enlarge the image for the image. At the same time, images with insufficient resolution and small size can enlarge without distortion or blurring problems.


Bigjpg uses the latest artificial intelligence deep learning technology – deep convolutional neural network. It will supplement the noise and jagged parts to realize the lossless enlargement of the picture. So the magnification effect is very good, the color is well preserved, and there will be no glitches and ghosting on the edges of the picture.


Upscalepics uses tens of thousands of real-world images to train a neural network. When fed a low-resolution image, it will try to predict the high-resolution image with high accuracy, supplementing the missing information.

5. Imageenhan

Imageenhan can choose different degrees of image noise reduction, and it has built-in a variety of AI models, which can repair low-resolution and blurred images and turn them into high-definition large images. In addition, the noise that affects the image quality is basically invisible on the enlarged picture.
