Why is there a grid behind a transparent background PNG

adobe-photoshoptransparency

When I open a transparent background PNG, I see a grey-white grid.

Is the grid embedded into the file? How can I change it?

Best Answer

That's there to show that it's a transparent background; it's not actually embedded since it's just the way it's displayed in Photoshop. When you drop that onto your web page / document you won't see the grid.

You can change the parameters for the grid in Photoshop → Preferences → Transparency & Gamut.
