Format comparison

BMP vs GIF

How do BMP and GIFcompare? Here's everything you need to know to choose the right format — and how to convert between them.

Bitmap Image File

BMP is an uncompressed raster image format native to Windows. While it produces very large files, BMP preserves every pixel with zero quality loss, making it useful for raw image data and legacy applications.

Graphics Interchange Format

GIF is a widely recognized format best known for animated images and short loops. While limited to 256 colors, GIF's animation support and universal compatibility make it a staple of web culture.
