Format descriptions
BMP — BMP is a lossless raster image format developed by Microsoft. It delivers perfect quality but produces very large files.
GIF — GIF is a bitmap format with a 256-color palette, best known for animations. It uses lossless compression but limited colors, so it is not ideal for photos.

What happens when converting BMP to GIF?
The BMP data is decoded inside your browser with WebAssembly and re-encoded to the GIF specification, so no file is ever uploaded to a server. GIF can encode losslessly, so this conversion adds no further quality degradation to data that is already compressed. GIF supports animation, so a static BMP image can be turned into a moving clip.
Frequently Asked Questions
What is image conversion?
Image conversion changes an image file from one format to another, for example from BMP to GIF, while keeping the image content.
Are my images uploaded?
No. This tool processes images directly in your browser. Your images are never sent to a server.
Which image formats are supported?
This tool converts BMP images to GIF, all in your browser.
Is it really free and unlimited?
Yes, the tool is completely free and you can convert as many images as you want, with no limits.
Does it work on mobile too?
Yes, it works on any modern device, including smartphones, tablets and desktop computers.
Which format will the result be in?
The converted image will always be in GIF format, ready to download and use.
What happens to transparency when converting to JPG?
JPG does not support transparency. If your image has an alpha channel (for example a PNG or WebP with a transparent background) and you convert it to JPG, the transparent areas are flattened and may appear with a dark or black background. Use PNG, WebP, TIFF or GIF output to preserve transparency.
