// ABOUT GIF
GIF is a legacy format dating to 1987 that supports animation and simple binary transparency. It is limited to a palette of 256 colours per frame, which means photographic content will undergo colour quantisation. Despite its age, GIF remains ubiquitous for short animations and reaction images across messaging platforms and social media.
// ABOUT BMP
BMP is an uncompressed raster format developed by Microsoft. It stores raw pixel data with no compression whatsoever, resulting in very large files but universal compatibility across Windows applications. BMP is most useful when a downstream tool or legacy application requires raw, uncompressed pixel data.
// WHY CONVERT
Converting GIF to BMP is useful when you need your image in a format suited for legacy Windows applications, game engines requiring uncompressed textures, hardware tools, and scenarios where decompression overhead must be zero. Since BMP stores raw pixel data, the resulting file will be significantly larger than the GIF source, but no quality is lost. Image Toolz runs the entire conversion directly in your browser. Nothing is uploaded to any server — your files remain completely private on your device. The tool handles images up to 200 MB and most conversions complete in under a second.
// FAQ
What is GIF?
GIF is a legacy format with a 256-colour palette, supporting animation and indexed transparency.
What is BMP?
BMP is an uncompressed Windows format storing raw pixel data. Files are large but universally compatible with Windows applications.
Will converting GIF to BMP lose quality?
No additional quality is lost. The BMP faithfully represents the decoded GIF pixels. GIF's 256-colour limit means colours were already reduced before conversion.
Is it safe to convert my files here?
Yes. All conversion runs entirely in your browser. Your images are never uploaded to any server and nothing leaves your device.
