Why convert BMP to GIF?

Introduced in 1988 by Microsoft, BMP was great for its time. But GIF (created in 1987 by CompuServe) offers lossless compression and 8-bit – a massive leap forward. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. This is one of those changes that pays for itself almost immediately.
