About BMP Format

Bitmap Image File

The classic uncompressed Windows image format.

Overview

BMP (Bitmap) is a raster graphics image file format used to store bitmap digital images, independently of the display device. It is one of the oldest image formats still in use, historically associated with the Microsoft Windows operating system.

Technical Details

BMP files typically store color data for each pixel in the image without any compression. This results in very large file sizes but perfect quality and extremely fast decoding. While it supports RLE compression, it is rarely used.

History

Introduced with Windows 3.0 in 1990. It was the standard format for Windows wallpapers and system graphics for decades.

Common Use Cases

  • •System Graphics: Legacy Windows applications and embedded systems.
  • •Clipboard Data: Often the format used when copying/pasting images in Windows.

Advantages

  • Simplicity
  • Quality

Limitations

  • File Size
  • Web Usage

About ICO Format

Microsoft Icon

The standard format for icons on Microsoft Windows and the web (favicons).

Overview

The ICO format is a container for one or more images at multiple sizes and color depths. It allows a single file to store appropriate icons for different display contexts (e.g., 16x16 for menus, 256x256 for desktop). It supports transparency and, in modern versions, PNG compression.

Technical Details

ICO files contain a header followed by an icon directory that lists each image entry. Each entry can use either BMP (uncompressed) or PNG compression. The format supports 1, 4, 8, 16, 24, and 32-bit color depths with optional alpha channels.

History

Introduced with Microsoft Windows 1.0. It became the standard for website favicons with the release of Internet Explorer 5.

Common Use Cases

  • •Windows Application Icons: Primary icon format for Windows applications and system files
  • •Website Favicons: Standard format for website icons displayed in browser tabs and bookmarks
  • •Desktop Shortcuts: Icons for Windows desktop shortcuts and file associations

Advantages

  • Multiple Sizes
