Turn off text auto select when using a picture OF text to make a sticker

How do I turn off text auto select when using a picture OF text to make a sticker. I have a picture of two words and I want to make that a sticker, but the text is getting auto-selected so that I can copy/paste into a document. I just want to make the picture OF that text (two words) and NOT just the text that iOS selected. This is the picture of the text that I want to use to make a sticker.
