What is BMP and What is WEBP?
BMP (Bitmap) is an uncompressed image format native to Windows. BMP files are lossless and store every pixel without compression, resulting in very large file sizes. It is required by some legacy Windows applications and hardware devices that do not support modern formats.
WebP is Google's modern image format designed for the web. It delivers 25–35% smaller file sizes compared to JPG and PNG at equivalent quality. WebP supports both lossy and lossless compression, as well as transparency. It is supported by all modern browsers including Chrome, Firefox, Safari, and Edge. Learn more about WEBP →
