Raster (or bitmap) images are generally what you think about when thinking of images. These are the types of images that are produced when scanning or photographing an object. Raster images are compiled using pixels, or tiny dots, containing unique color and tonal information that come together to create the image.

The article delves into TIFF vs PNG differences to help users understand the unique strengths of each option. By comparing TIFF file and portable network graphics (the formal name for PNG files) characteristics, we explore aspects such storage space, file quality, and compatibility.

Some image types such as TIFF are great for printing while others, like JPG or PNG, are best for web graphics. The list below outlines some of the more common file types and provides a brief description, how the file is best used, and any special attributes the file may have.

Unlike GIF, PNG supports 24‑bit images and produces background transparency without jagged edges; however, some web browsers do not support PNG images. PNG format supports RGB, Indexed Color, Grayscale, and Bitmap mode images without alpha channels. PNG preserves transparency in grayscale and RGB images.

Limited File Storage: Bitmap images can take up a lot of storage space, especially high-resolution files like BMPs. For applications requiring efficient storage, such as websites with numerous images, use more compressed formats like JPEG or PNG, or leverage vector graphics for simpler images.
