Transform your BMP files into GIF format instantly within your browser.
BMP (Bitmap, also called Device Independent Bitmap) is a raster format created by Microsoft for early versions of Windows around 1990. Most BMP files store pixel data with little to no compression, so file sizes scale directly with image dimensions and color depth rather than actual visual complexity. This simplicity made BMP easy for any program to read and write reliably, but it also means a BMP is often 5-10 times larger than an equivalent JPG or PNG. It's still occasionally produced by legacy Windows tools, screenshot utilities, and some scientific or industrial imaging software that prioritize a simple, uncompressed structure.
GIF (Graphics Interchange Format) was introduced by CompuServe in 1987 as a platform-independent format for sharing color graphics over slow, modem-speed connections. It uses lossless LZW compression on indexed images limited to a palette of 256 colors, and its defining feature is native support for simple looping animation, storing several frames with their own timing directly inside one file. GIF also supports single-color binary transparency. Even though modern formats like WebP and AVIF now offer full-color animation with much better compression, GIF's near-universal support in browsers, chat apps, and social platforms keeps it firmly embedded in everyday web culture.
