What BMP to GIF conversion does

Convert a BMP image to a static GIF directly in your browser. GIF remains one of the most universally supported image formats, useful for simple graphics, icons, and older systems that expect a .gif file specifically.

How to convert BMP to GIF

1. Choose a BMP file.
2. Select Convert & download.
3. Save the .gif file from your browser downloads.

Why use this conversion

Some platforms, forums, or legacy systems only accept .gif uploads, or you specifically need the broad compatibility GIF has enjoyed since the early web.

Transparency and output quality

GIF transparency is all-or-nothing per pixel — either fully transparent or fully opaque. This tool automatically reserves a transparent palette entry when the source has any transparent pixels. GIF is limited to 256 colors total. This tool picks the closest 256-color palette automatically using color quantization, which can introduce small color shifts on photographic or gradient-heavy images.

Privacy and local processing

• Processing occurs locally in the browser.
• Files are not uploaded to Looty Tools for conversion.
• Converted files remain on your device.

Limits and known issues

• Input: BMP (.bmp) only, up to 25.0 MB and 8,192 px per side.
• Output is always a single static image — never animated, regardless of the source.
• Transparency is kept only when the browser decodes a real alpha channel from the source BMP; most BMP files have no transparency.
• Metadata is not preserved in the downloaded file.

BMP to GIF FAQ

Why convert BMP to GIF?

Some platforms, forums, or legacy systems only accept .gif uploads, or you specifically need the broad compatibility GIF has enjoyed since the early web.

Is the GIF output animated?

No. Output is always a single static image, limited to 256 colors chosen automatically from the source.

Does GIF output keep transparency?

GIF transparency is all-or-nothing per pixel, not partial like PNG. This tool reserves a transparent palette entry automatically when the source has transparent pixels.

Does the source BMP actually have transparency?

Rarely. Most BMP files have no alpha channel at all. When the browser does decode real alpha data from a 32-bit source BMP, it is preserved in output formats that support transparency.

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 BMP — the tool checks the "BM" header bytes, not just the filename or extension, before decoding.
