To import an invisible background into Roblox, use a PNG with transparency, then set the image object’s background transparency to 1 in Studio. Roblox dev forum advice also notes that if the image already has a solid background, making the UI background transparent will not remove that baked-in background.

What to do

  1. Create or edit the image in an editor that supports transparency.
  2. Save it as a .png , not a JPG.
  1. Upload it to Roblox as an image asset.
  2. Put it in an ImageLabel, ImageButton, Decal, or similar object.
  3. Set the object’s BackgroundTransparency to 1.

If it still looks white

  • Check that the source file actually has transparent pixels.
  • Make sure you did not export it as JPEG, which does not preserve transparency.
  • For UI images, also confirm ImageTransparency is not making the whole image disappear.
  • For decals or icons, some users also set the image background transparency to 1 and adjust the object’s colors if needed.

Simple example

If you are making a crosshair or button icon, export a transparent PNG, upload it, place it in an ImageLabel, and set BackgroundTransparency = 1. That is usually enough to make the background invisible in Roblox Studio.

Note

The Roblox documentation page you surfaced is about the importer for 3D model formats like .fbx, .gltf, and .obj, so it is not the main path for transparent 2D images.

TL;DR: use a transparent PNG, upload it, then set BackgroundTransparency to 1.
