Getting a transparent picture, and when it fits.
Generating with transparency
Asking for a transparent background up front works best for objects, icons, stickers and products that will sit on top of something else. The result has no background at all, so it can go on any colour or picture. In Cutlin it is an option when you make a picture.
Which file to keep
Transparency survives only in formats that support it, such as PNG; a JPEG fills the transparent area with a colour. When a website or printer asks for a transparent PNG, that is the file to send.
Need it to scale too?
For a logo, an icon or a sticker that has to stay sharp at any size, make it as a vector instead: an SVG has no background unless you draw one, and it never blurs when enlarged.
