I just upscaled a bunch of images and admittedly they were already large images so now they are 13000x19000 after upscaling. Each image is now approximately 1GB in size which is pretty ridiculous. I ran the images through XnConvert and it lowered the file sizes down to about 7MB each and it seems to have not lost any image quality (I’m viewing on an 8K TV). Why are the file sizes so huge when using Gigapixel when they don’t have to be.

Did you ever find out why? I came here with the same question.
sorry for the late reply. i haven’t figured out why. I can say that with the newest iteration of Gigapixel it isn’t as bad. Now it seems to depends on how much you are enlarging so for example if my source photo is 3MB and i decided to do a 2x enlargement then it will now be 6MB, if I do 3x then it will be 9MB. It has definitely gotten better with the newer versions. And as I mentioned in my original post there is the option of using XnConvert to shrink the file size without losing much quality. Although, it seems lately that that program has gotten worse. I’ve used it for a few photo sets and it actually either doesn’t shrink the file or it makes the file size a tiny bit larger.
I came here for this topic too… I used to have a 2x upscale about 7k x 10k pixels and it about around 20mb. Now I have to upscale similar images 6x and they end up over 500mb. I don’t understand what changed?? i can’t work with files that large…
Same problem here, any solution guys ?
