What is the best tool to improve the quality of old photos with AI?

Hey everyone! I’ve been searching for a good tool to enhance the quality of my old photos. They’re pretty low-res, and I’m hoping to find something that can help me upscale them without losing too much detail. I came across a few options, but I’m not sure which one to go for. Has anyone here used a reliable tool for this purpose? I’ve heard about upscale image tools and wondered if there are any specific recommendations. If anyone has experience with it or can suggest other similar tools, I’d appreciate some advice! Thanks in advance!
