Drag your files here
Or paste them with Ctrl+V. They never leave your device.

Limits: Photos lose a lot of colour; here only the first frame of an animated GIF is converted.
BMP stores pixels uncompressed, as-is, the way Windows has since its early versions.
Strengths: Very old software and devices that know nothing about compression can read it.
Limits: It is huge: a photo in BMP takes ten times more space than in JPG.
No. The GIF to BMP conversion runs entirely in your browser, with code downloaded from this site and executed on your device. You can check it in the Network tab of the developer tools or by going offline after the page loads.
BMP has no transparency: transparent areas of the GIF are filled with the colour you choose (white by default).
No: BMP stores the image losslessly, so it stays exactly as it was in the GIF.
Your device’s memory sets the limit: on desktop, images up to about 100 megapixels; on mobile, up to 16.7. If an image is too large you are told before it starts.
Yes. Drop as many GIF files as you like: several are converted at the same time, depending on your processor cores, and when they finish you can download each BMP or all of them in a ZIP.
