Upscaling GPT Image 2.5 output 10x with a free tool

After generating three images with GPT Image 2.5 that were too low-resolution to print, a user found a free upscaling site that at 10x takes each image to about 100MB and over ten thousand pixels.

用最新的GPT image 2.5 生成了三张图。如果打印的话分辨率还是不够，然后发现了一个免费的放大网站，不过免费只能处理3张。换浏览器或清cookie后可以处理更多张。拉到10倍放大，图片会从20多m升到100m一张，像素过万。图片放大工具见评论区
