Why does each animation come in different sizes, backgrounds and formats?

If you resize a .GIF image, you typically lose some quality and crispness. We have included several popular image sizes to avoid having to resize the image to fit your project needs. The various sizes are ideal for on-screen viewing of e-mails, web sites and other digital media.

The animations also come with different background variations to better fit your project. As opposed to many image file formats (like .JPG), a .GIF can contain fully transparent areas, ideal for placing the animation on top of non-white backgrounds.
