BMP vs PNG: 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

PNG (Portable Network Graphics)

PNG is a lossless image format that supports transparency, making it ideal for graphics, logos, and images that require crisp edges or transparent backgrounds.

•Compression: lossless

•Transparency: Yes

•Animation: No

•Since: 1996

Converting from uncompressed Bitmap Image File to Portable Network Graphics will significantly reduce file size while preserving exact image quality.

Portable Network Graphics 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 PNG:

•logos and icons
•images with text
•graphics requiring transparency
•screenshots
