What is a text on image tool?

A text on image tool (also called add text to photo or text overlay tool) lets you write words directly on your pictures.

The result is a single PNG file with your text overlaid — perfect for social media posts, watermarks, memes, marketing graphics, blog headers, and greeting cards.
