Pixel Count reduced when uploaded

Hiya, I have a major issue for my UI based game, its main UI (A map of the world) had a horrible issue where in roblox its pixel count is severly reduced making the main ui just horrible

What its meant to look like:

Roblox Redition:

If you just look at a side by side comparison the results are quite… Differnt

Is there any way I can do this?

It’s from a couple years ago, but here goes:

This may not be exactly the answer you are looking for, but its possible that for the UI you have the resample mode set to default which you can change to pixelated by selecting the dropdown box

having it on default causes some images to look like this

while changing it to pixelated improves the image

Thank you both, unfortunately, neither works to what I need but I think I’ve thought of a work around since Roblox uses images that are 1024 x 1024 I will just have to spilt it up into segments and then peice the segments together.
