How to Convert GIF to BMP in Your Browser

Converting a GIF image to BMP produces an uncompressed 24-bit bitmap that older Windows software and some print or legacy pipelines expect. This guide covers the steps and what to know about transparency and file size.

Step-by-step conversion

  1. Open /tools/gif-to-bmp.
  2. Choose a GIF file — the content is validated before conversion, not just the filename or extension.
  3. Select Convert & download.
  4. Save the .bmp file from your browser downloads.

Transparency and file size

BMP output here is 24-bit RGB with no alpha channel, so transparent pixels are flattened onto a white background, the same convention used for JPG output. Because BMP is uncompressed, the resulting file is usually larger than the source.

Source-specific behavior

This tool is for static GIF conversion only. Animated GIF: only the first frame is converted, and the result will not be animated.

Privacy

Conversion runs locally in your browser. The file is not uploaded to Looty Tools servers for this workflow.

Convert GIF to BMP FAQ

Why would I need BMP instead of GIF?
Some older Windows software, print workflows, or legacy tooling specifically expects an uncompressed BMP file.
What happens with an animated GIF file?
Only the first frame is converted, and the result will not be animated. This tool is for static GIF conversion only.
Does BMP output keep transparency?
BMP output here is 24-bit RGB with no alpha channel, so transparent pixels are flattened onto a white background, the same convention used for JPG output. Because BMP is uncompressed, the resulting file is usually larger than the source.
Are my files uploaded?
No. Conversion runs locally in your browser and does not upload your file to Looty Tools servers.
What is validated before conversion?
The file must actually be a GIF — the tool checks the GIF87a/GIF89a signature bytes, not just the filename or extension, before decoding.
