Type of Digital Image Files:

There are mainly 5 types of Digital Image Files that helps in storing the image.

1) TIFF (Tagged Image File Format):

TIFF is also known as TIF and the extension of this file type is “.tif”. This type of file is most commonly used in photo softwares like photoshop. The images having tif extension are uncompressed and thus imager data is in detailed way and the files are big in size.

2) JPEG (Joint Photographic Experts Group):

JPEG is also known as JPG and the extension of this file type is “.jpg”. The image of JPEG file is compressed and thus it stores a large amount of data in small size file. The digital cameras are also storing the image with this extension as due to small size format, one can takes lots of photos in one camera card.

3) GIF (Graphic Interchange Format):

GIF images use the extension “.gif” which means the file type stored in this format ends up with “.gif”. Through this format, images are also compressed but image compression is different as compared to JPEG. In GIF, the image compression is lossless which means that the data doesn’t lost at the time of compression but file size is not as small as it is in JPEG format.

GIF format is also used in animations but due to less number of colors, this file type is not used for photography purpose.

4) PNG (Portable Network Graphics):

While at the time of photography, PNG is also not good as compared to JPEG, as the file stored is larger in size. In images that contain text, we generally use PNG format as by using this, the image looks less ““bitmappy.”

5) Raw image files:

Data contains in this type of file is usually from a digital camera. Raw files contain a large amount of data, and as a result, the files are extremely larger in size. The files are called raw because the data stored in it is generally not processed and is uncompressed. Before editing or color correction, the raw files are firstly converted into TIFF format.

Advantage of PNG:

  • The images that contains PNG format are of low-resolution, thus the image looks of good quality and is loaded quickly.
  • PNG supports variety of colors and is also a good format for editing of images.
  • At the time of compression, it doesn’t loss any data.
