BMP vs WebP Format Comparison

BMP (Bitmap) is an uncompressed image format that stores pixel data without any compression, resulting in large file sizes. While BMP preserves perfect quality, the files are impractical for web use and sharing.

WebP is Google's modern image format that offers superior compression. It supports both lossy and lossless compression, transparency, and animation. Converting BMP to WebP can reduce file sizes by 80-95% while maintaining excellent visual quality.
