Convert BMP to GIF
Free online BMP to GIF converter. Drag and drop files, convert in batch, and download, without ever uploading to a server.
Why convert BMP to GIF?
Convert BMP to GIF for a rare case: a legacy system exports uncompressed bitmaps, but the destination (an old forum, a simple embedded display, a retro-style project) only accepts GIF. You get a big size drop, capped by GIF's 256-color palette.
Tips
- Photos and gradients will band hard at 256 colors. This pairing suits flat graphics, icons, and simple diagrams best.
- Processing stays entirely in your browser. The BMP never leaves your device.
Two old formats, two different problems
BMP and GIF are both decades old, but they made opposite trade-offs. BMP kept every pixel's exact color and paid for it in enormous, uncompressed file size. GIF compresses well but caps you at 256 colors total, so smooth gradients and photographic detail get flattened into visible bands. Converting between them trades one limitation for the other. You'll get a dramatically smaller file, but only by giving up most of the color range BMP was faithfully storing.
Frequently asked questions
How do I convert BMP to GIF?
Drop your BMP file into the converter above, adjust the quality if needed, and click "Convert to GIF". The conversion happens entirely in your browser. Your file is never uploaded to any server.
Is the BMP to GIF conversion lossless?
GIF is limited to 256 colors, so photos can band. This is a compatibility export, not a quality-preserving one. Prefer JPG for photos unless a form requires GIF.
Is there a file size limit?
The tool can handle files up to about 20 MB per image. Since processing happens in your browser, the practical limit is your device's available memory. Most modern devices can comfortably batch-convert dozens of images at once.
Are my BMP files uploaded to your servers?
No. All BMP to GIF conversion happens entirely client-side. Conversion uses the Canvas API. Your files never leave your browser.
Why would a BMP need to become a GIF instead of a smaller modern format?
The usual reason is that whatever is on the receiving end is as old as the BMP itself. Some embedded displays, retro hardware projects, legacy forum software, and simple hobby scripts were built to parse GIF specifically and never added support for anything newer like PNG or WebP. If your destination can accept a modern format instead, PNG or WebP will almost always give you a smaller, better-looking result than GIF for anything beyond flat, simple graphics.
