Photographs Question

[Pinball-Fantasies]

I have a large number of photographs , is it possible to get these converted to 4k resolution at 3840 x 2160
I have manage to clean the photographs up and they are better quality

Can anybody recommend a programme or online ?

Are you down sizing or up sizing, i’m not sure from how you describe it.

What file format are the original files?

Would like to upscale to 4K
Format are JPEG

I'm inclined to agree. By upscaling, your not going to get any more detail in the picture than what you already have*. I'm also now of the mind that sometimes the original image ( or touched up original image ) is the best one to keep for the longer term, and only resize it when you need to resize it. JPEG images are lossy formats, and the more times you go round the loop of editing and saving, the more you lose over time.

As Scuzi asks, why do you need to resize? Is it for something like a slide show on a TV ?

* Admittedly, AI enhanced upscaling is getting better such that it can interpolate may insert more detail based on its ai learning ... but be clear that the detail will not have come from the original image.

I have new 4K monitor , i just wonder the best way to improve the picture quality maybe on-line
