JPG/JPEG image compression: Pros and Cons

JPEG format is the most commonly used image format. Both JPG/ JPEG are widely used for storing images and photographs and often used interchangeably considering there are no differences between the two of them. There are two categories of JPEG formats

Exif format (used by cameras for capturing and storing photographs)

JPEG/JFIF format (used for image transferring and storage)

Compressing images and photographs with a lot of gradients in JPEG format are one of the most commonly used standards especially with big pictures. Though it may not be ideal for images with solid lines or text. There are both pros and cons to it. 

Pros of JPEG/JPG Format

The JPEG/ JPG format has several advantages, some of which are as follows;

  • This format is extremely portable and has a long history.
  • This format is compatible with almost every image processing app
  • This format is easily printable and compatible with most hardware devices
  • This format can also be used to store high resolution fast-moving images which would normally be blurred in other formats considering their small size. 
  • Images of this format can easily be stored from a camera to storage devices.
  • This format can be reduced and compressed making it most suitable for image transfer

JPEG images can be easily compressed down to 5% of their original sizes. This makes them pretty advantageous for images over the internet considering they consume less bandwidth. 

Cons of JPEG/JPG Image compression 

  • JPEG compression can make the image lossy. This means that after image compression the image loses certain contents. This may be referred to as lossy compression. 
  • The quality of the image is also reduced after the compression considering the loss of actual content of the image
  • Images with sharp edges and lines are not suitable for JPEG image compression considering JPEG image format is not suitable for handling animated graphic images.
  • JPEG is not supportive of layered images or editing graphic images. This is because it is not possible to work on layers and edit graphic images with JPEG format. 
  • JPEG is supportive of 8-bit images only. This means that the high resolution digital camera images that are 10,12, 14 or 16 bit can really get lossy with image compression considering the extra information is discarded from them and the image quality is decreased. 

PDF to JPEG file conversion

Many times you may need to convert the PDF to JPG files. The process is fairly simple and you can easily do it online by finding either an online converter or an offline converter. With an online converter all you would have to do is select the PDF that you want converted from your computer, Dropbox, URL or any source and add it in the converter. All you have to do from thereon is to simply wait for the conversion before you can download your file. 


JPEG/JPG images are mainly used for small sizes-portable images. You should only use them with images with smooth edges and color contrasts. JPEG is not a good choice for high resolution images with sharp contrasts. Moreover with JPEG conversions you should keep the lossy compression in consideration. Based upon your desired results you may choose other formats that may be more suitable to your needs.
