I’m trying to save my black and white drawings as PNG 24 files with all the white parts transparent. I did it successfully with few of my drawings with the option “save for web”
However today I failed to reproduce it. I always end up with no transparency as you can see on my screenshot. Anyone can explain me the reasons why ?
PS always gives you different ways to do something.
You can also use blending options by double clicking on your artwork layer
and, using the Blend if sliders, eliminate the white background:
You can add a color fill layer below to check your work but before you save, make sure you turn it off or delete it. Then save as png with transparency.
