if you want to add a header or similar above your post you just need the drawing without background, in most drawing apps you can do that by just deselecting the background layer in the layer "menu" and it should save transparently :3
personally, ive found procreate can be a bit annoying with that (doesnt save with transparent background for whatever reason) but i still havent found a way to fix that so i couldnt help you regarding that haha
otherwise, there are websites/apps that let you remove the background of images but i dont really have experience with that
hope this makes sense my brain is a bit scrambled
