GIF to BMP Converter

About GIF to BMP

Converts a GIF to a bitmap by decoding the still image and writing it out as a genuine 24-bit BMP. The audience is mostly people feeding legacy Windows programs or embedded systems, where BMP is a common lowest-common-denominator input.

How to use it

1. Drag a .gif file into the dropzone, or click to choose it.
2. Check the still preview; animated GIFs display a single frame.
3. Press Convert to BMP. No controls appear, because BMP is not tuned by quality.
4. Use Download BMP to keep the file.

When to use it

• Giving a legacy application a bitmap version of a small GIF graphic.
• Preparing a splash image for a device whose loader accepts only bitmaps.
• Creating an uncompressed reference copy of a palette image for testing a parser.

Questions about GIF to BMP

Why does a GIF-to-BMP file get so much larger?

GIF compresses with LZW and stores only 8 bits per pixel, while a typical 24-bit bitmap keeps 24 bits per pixel uncompressed. A 640×480 image comes to 921,654 bytes, about 900 KB.

Will the animation be kept?

No. BMP has no frames, so at most one still is produced, and it is the frame the browser draws.

Is the file actually in BMP format?

Yes. Browsers cannot encode BMP from a canvas, so the tool writes the bitmap itself, with a BM header and uncompressed 24-bit rows, and any BMP reader can open it.

What about the transparent color?

A 24-bit BMP has no alpha, so transparent pixels are written as white. If you need the transparency preserved, convert to PNG or ICO instead.
