When you convert an image to jpg format, or re-save an image in that format, you are normally asked (depending on the program you are using) to specify both a pixel count and a figure called 'quality' or something like that. You should enter the highest possible 'quality' figure, normally 100. The 'quality' figure is separate from the pixel count (eg 2000x1000) that you also need to enter when saving.

Hello!

Thanks a lot for your reply... But I guess I'm a bit lost at this, still. What is degraded quality? Is it a high quality file that's somehow been shrunk?

Thanks again...
