I have a group logo, however, it isn’t centred, even tho the image is. I’m pretty sure group logos are 256x256, so I made a 256x256 copy of the logo, which is centred, but when uploaded doesn’t become centred.
This often happens when you use specific editors, my best guess would be to actually import into a different editor and center it. It might work then, also make sure it is a PNG file.
This is most likely the way you designed it. When you designed it, It was in the middle, but since the image is most likely smaller in the Roblox version it is not centered.
I had a similar issue making thumbnails once where even with the right pixel size it would still come out slightly smaller then it should have been. Software can always be buggy and weird, so for sure consider using different platforms for creating your logo if it is not coming out the way you want it to. Also I noticed that as @Hamburger_Hoovy pointed out, you for sure still CAN have a scaling issue. Some photo editing software for some reason even with the correct size still downloads your logo incorrectly.
can you show us the file of the logo alone? I’m assuming you’re using a software that automatically crops the image when you save and that you might need to use paint.net or something
