About this tool

What is AI Image Upscaler?

AI Image Upscaler enlarges a small image 2x, 3x or 4x using an AI super-resolution model, which reconstructs detail and stays much sharper than a plain resize. It is the tool to use when you need a bigger version of a low-resolution image.

Things to keep in mind

  • AI upscaling takes longer than a normal resize and cannot create detail that never existed.
