PNG with transparency

[slimjim3k]

Would it be possible to have a tickbox somewhere that makes the background transparent?

I looked for similar discussions, but the other seem to involve specific colors and a specific tab.

I am asking for the software to output an image as usual but the subject is on top of a transparent background for use in other software like photoshop. Basically instead of filling a background with stuff, the background is filled with transparency and output that way.

you could use the txt2img2mask extension as a background removal tool for this, it works well enough, you would have to select only black and white option
