When uploading a decal to Roblox, images that are low resolution are upscaled, making the image blurry.
To reproduce this issue, get any image under 1024x1024 and upload it as a decal. It will appear blurry as it’s upscaled. This not only increases the file size of the image, but also decreases the quality.
Images I used:
(16x16 image)
(256x256 image)
Expected behavior
I expect the image to not upscale if it’s under 1024x1024 pixels, maintaining a lower file size and keeping the image quality.
