What is GIF to BMP Converter?

GIF to BMP converts GIF images into Windows BMP (bitmap) files. BMP stores raw, uncompressed pixels, which makes it useful when a program or device needs a plain bitmap with no compression artefacts.

This converter decodes your GIF with the browser's image engine and writes a standard 24-bit uncompressed BMP. Animated GIFs are flattened to their first frame, and transparency is composited onto a white background because 24-bit BMP has no alpha channel. Nothing is uploaded to a server.

How to Use GIF to BMP Converter

1

Drop a GIF file onto the upload area or click to browse

2

The first frame is decoded and written as a BMP instantly

3

Compare the BMP preview with your original

4

Click Download to save the BMP

Common Use Cases

  • Producing a raw bitmap for software that requires uncompressed BMP input.
  • Converting a GIF frame to BMP for embedded systems or legacy tools.
  • Creating a BMP from a GIF for image-processing pipelines.
  • Exporting a GIF still as a plain Windows bitmap.

Example Input and Output

A small GIF converts to a larger, uncompressed 24-bit BMP.

Input
sprite.gif (12 KB, 256-colour GIF)
Output
sprite.bmp (190 KB, 24-bit BMP)

How This Tool Works

The browser decodes the GIF first frame to canvas pixels, composites any transparency onto white, and writes a 24-bit uncompressed BMP file for download.

Format

Output is a 24-bit BI_RGB BMP with bottom-up rows — the most widely compatible bitmap variant.

Privacy

Your image never leaves the browser; conversion is fully client-side.

Frequently Asked Questions

Is my GIF uploaded anywhere?

No. Decoding and BMP encoding run entirely in your browser.

Why is the BMP so much larger?

BMP stores every pixel uncompressed, so the file is far bigger than the compressed GIF.

What happens to transparency?

24-bit BMP has no alpha channel, so transparent areas are composited onto white.

Does it keep animation?

No. BMP is a still format, so an animated GIF is flattened to its first frame.
