How do I make an image partly transparent?

Choose the opacity percentage and run the operation. The result changes transparency rather than simply adding a white overlay.

What is the difference between solid and gradient opacity?

Solid mode applies the opacity treatment uniformly. Gradient mode varies the transparency spatially, with linear and radial choices.

Transparent pixels combine visually with the background behind them. Check the downloaded image on the background where you plan to use it.
