- Description
- The BTN file format is associated with JustButtons, a software tool used for creating animated bitmap images specifically designed for web and presentation use. These files contain both the graphical data and the animation settings for buttons, such as hover or click effects, making them ideal for interactive web elements. The BTN format allows for the easy integration of visually appealing, animated buttons into websites without requiring extensive coding knowledge. This format is particularly useful for web designers and developers looking to enhance user interface elements with animated graphics.
- Image file saved by the Krita painting program. A Krita file is a zip archive holding the full layer stack: each layer's pixel data as compressed tiles, its name, position, opacity, blending mode and visibility, plus a merged preview of the whole image.
