How to convert BMP to GIF
- Drop your BMP files on the box above, or click it to choose them (up to 30 at once).
- Check the settings.
- Press Convert. Each file is processed on your device and shows its old and new size.
- Download the files one by one or take them all as a ZIP.
What changes when you convert BMP to GIF
- GIF can hold at most 256 colours. Simple graphics with few colours convert exactly; photos are reduced to a 256-colour palette chosen for that image, with optional dithering to smooth gradients.
- BMP images have no transparency, so there is nothing to lose there.
- Camera details and GPS location (EXIF) are not copied into the new file. Photo orientation is applied to the pixels first, so the result is the right way up.
About BMP and GIF files
BMP is the old Windows bitmap format. It stores every pixel uncompressed, so files are very large, but almost any program — including very old ones — can read it.
GIF is limited to 256 colours per image and supports on/off transparency and animation. It is lossless for simple graphics, but photos have to be reduced to 256 colours. It is a good choice for simple graphics, icons and places that only accept GIF.
Limits
Up to 30 files of 25 MB each per batch and images up to 50 megapixels — beyond that browsers run out of memory, so the tool says so instead of producing a broken file. Files that are not images, or are damaged, are rejected with the reason.
