This free BMP to GIF converter turns your .bmp images into .gif files. BMP turns up from legacy Windows software and scanners. It stores raw uncompressed pixels, so files are enormous for what they contain.
Because browsers cannot write GIF, this one runs on our server: the file is converted in memory and sent straight back. It is never written to disk, never logged and never stored.

What changes when you convert BMP to GIF
GIF is limited to 256 colours, so photographic images come out visibly banded. It is the right target for flat graphics and the wrong one for photographs.
BMP and GIF compared
| BMP | GIF | |
|---|---|---|
| Full name | Windows Bitmap | Graphics Interchange Format |
| Extension | .bmp | .gif |
| MIME type | image/bmp | image/gif |
| Compression | Lossless | Lossless |
| Transparency | No | Yes |
BMP: Uncompressed raw pixels, which makes the files enormous and the format trivial to parse. Mostly encountered coming out of legacy Windows software and scanners.
GIF: Limited to 256 colours with single-bit transparency, which makes it poor for photographs and fine for flat graphics. Still the most widely supported animation format.
Frequently asked questions
How do I convert BMP to GIF?
Drop your .bmp file onto the box on this page and the .gif file is ready to download in a second or two. There is no signup, no email, no watermark and no file limit beyond about 4 MB per upload — larger images are re-encoded smaller in your browser first, and the page says so when that happens.
Is this BMP to GIF converter free?
Yes, completely, with no account, no trial and no watermark on the output. We are a consultancy and these tools exist because we needed them ourselves; there is nothing to buy on this page.
Are my files uploaded anywhere?
This one has to run on our server, because browsers cannot write GIF. The file is converted in memory and returned immediately — it is never written to disk, never logged and never stored. If that is not acceptable for your file, use a desktop tool instead.
Will converting to GIF reduce the quality?
GIF is limited to 256 colours, so photographic images come out visibly banded. It is the right target for flat graphics and the wrong one for photographs.
Can I convert several BMP files at once?
Yes, up to 20 files in one go. Drop them all onto the box together and each one appears in the results list with its own download button.
