BMP vs AVIF: Understanding the Difference

BMP (Bitmap Image File)

BMP is a raster graphics format that stores images without compression, resulting in large file sizes but perfect quality preservation.

•Compression: uncompressed

•Transparency: No

•Animation: No

•Since: 1986

AVIF (AV1 Image File Format)

AVIF is a next-generation image format based on the AV1 video codec, offering exceptional compression efficiency that outperforms both JPEG and WebP.

•Compression: both lossy and lossless

•Transparency: Yes

•Animation: Yes

•Since: 2019

Converting from uncompressed Bitmap Image File to AV1 Image File Format will significantly reduce file size while maintaining good visual quality.

AV1 Image File Format supports transparency, but since Bitmap Image File doesn't include transparency data, your converted image will have a solid background.

When to use BMP:

•Windows system graphics
•applications requiring raw pixel data
•legacy software compatibility
•printing when file size doesn't matter

When to use AVIF:

•maximum compression efficiency
•modern web applications
•high-quality images at small sizes
•HDR images
