GIF to BMP Converter — Free, Online, No Upload

GIF's 256-color limit is its defining constraint. It was designed for the early web and simple graphics, not for use in software that expects a rich, uncompressed image. If you have a GIF that needs to be opened in a legacy Windows application, an older embroidery design tool, or a CNC software package that only accepts BMP, converting is the straightforward fix.

BMP is the uncompressed Windows-native format that virtually every piece of Windows software ever written can open without any additional codec or library. It doesn't support animation, but for still-frame GIFs (or when you want just the first frame of an animated GIF), BMP gives you an uncompressed version of exactly what the GIF contains.

The file size will increase substantially — a 100 KB GIF might become a 2–5 MB BMP because BMP stores uncompressed pixels. However, because GIF only has 256 colors, the BMP won't have more color information than the original GIF — you're getting uncompressed storage of a 256-color image, not a full-color image. If the GIF has transparent pixels, those will render as white or black in the BMP, as BMP doesn't support transparency in standard implementations. This conversion is primarily useful for software compatibility, not image quality.

Typical sizes: GIF 5–50 MB (animated clip (3s)); BMP 35–40 MB (12MP photo).

Both formats keep every pixel, so the BMP looks the same as the GIF.
