TIFF Image Format

TIFF (Tagged Image File Format) is a raster image file format that was originally developed by Aldus Corporation in 1986. It is widely used for storing and exchanging high-quality images, particularly in professional photography, graphic design, and printing industries.

Here’s an overview of the TIFF file format:

Key Features:

  1. Raster Image Format: TIFF stores pixel-based images, where each pixel is represented by a combination of red, green, and blue (RGB) values.
  2. Tagged Data Structure: TIFF files use a tagged data structure, which means that metadata, such as image dimensions, compression schemes, and color spaces, are stored in tags or fields within the file.
  3. Uncompressed or Compressed: TIFF images can be stored uncompressed or compressed using various algorithms, such as LZW (Lempel-Ziv-Welch), JPEG, or CCITT Group 4.
  4. Multi-Page Support: TIFF files can contain multiple pages or frames, making it suitable for storing multi-page documents, like faxes or scanned documents.
  5. Support for Various Color Modes: TIFF supports various color modes, including:
    • RGB (Red, Green, Blue)
    • CMYK (Cyan, Magenta, Yellow, Black)
    • Grayscale
    • Indexed Color

TIFF File Structure:

A TIFF file consists of:

  1. Header: A 2-byte identifier (II or MM) indicating the byte order (Intel or Motorola).
  2. Image File Directory (IFD): A table containing metadata, such as image dimensions, compression schemes, and color spaces.
  3. Image Data: The actual pixel data, which can be uncompressed or compressed.
  4. Tags: Optional fields that provide additional information about the image.

Advantages of TIFF:

  1. High-Quality Images: TIFF is well-suited for storing high-quality images with minimal loss of detail.
  2. Flexibility: Supports various compression schemes and color modes, making it suitable for different applications.
  3. Universality: Widely supported by image editing software, operating systems, and printing devices.

Disadvantages of TIFF:

  1. Large File Size: Uncompressed TIFF files can be very large, which may lead to storage and transfer issues.
  2. Limited Web Support: While some web browsers support TIFF images, they are not as widely supported as other formats like JPEG or PNG.

In summary, the TIFF file format is a versatile and high-quality raster image format that offers flexibility in terms of compression schemes, color modes, and multi-page support. However, its large file size can be a drawback in certain situations.
