Importing images from Photoshop

Hey, I have recently been getting into Photoshop, and I’ve been making my UI in there, but I try to import into Roblox studio, and the quality is bad/grainy even though its fine in Photoshop, I was wondering how I can make it higher quality in studio? Ive tried: Exporting at the same size it’ll appear in Roblox, Exporting in high canvas size, adjusting the Image properties in Roblox studio. None of these seem to work, help would be greatly appretiated!

how are the pixel dimensions on your image? roblox decreases quality when uploading, could be that. Are you also exporting on jpg?

Im exporting in different sizes for each image, but average 1500-3000. And I cant export in jpg, it doesnt support transparent backgrounds
