Convert BMP to GIF
About BMP
The Bitmap (BMP) file format is a simple, uncompressed raster graphics format developed by Microsoft for the Windows operating system. Because it's typically uncompressed, BMP files store raw pixel data, resulting in very large file sizes. While this ensures maximum quality, its inefficiency makes it impractical for web use or easy sharing. It's now largely a legacy format.
About GIF
The Graphics Interchange Format (GIF) is one of the oldest image formats still in common use on the web. It's best known for its ability to create simple animations. GIF uses lossless compression but is limited to a palette of only 256 colors, which makes it unsuitable for complex photographs but great for simple graphics, logos, and of course, animated memes.

Frequently Asked Questions
Is there any reason to use BMP today?
In modern workflows, there are very few reasons to use BMP. Its primary advantage was its simplicity and wide support in early Windows applications. For almost any purpose, formats like PNG (for lossless quality) or TIFF (for professional work) are far superior choices.
Does BMP support compression?
While the BMP format does support a simple lossless compression method called Run-Length Encoding (RLE), it is rarely used and not very effective. The vast majority of BMP files you encounter will be uncompressed.
Why is GIF so popular for animations?
GIF's popularity for animations stems from its simplicity and universal browser support. It's an easy, lightweight way to display short, looping animations without needing plugins or video players. Modern formats like APNG or WebP offer better quality, but GIF's legacy and ease of use keep it relevant.
Can a GIF have more than 256 colors?
No, a standard GIF is limited to a 256-color palette for the entire animation frame. While techniques exist to simulate more colors through dithering, the fundamental limitation remains, which is why GIFs are not good for photographic content.
