PNG Vs JPG: Which One is Better For Your Website?

Why does choosing the image file format matter for your site? Images beautify your website and convey a stronger message about your brand. Ultimately, it triggers emotions and improves your site’s traffic. When you choose images with larger file formats, it reduces the speed of your website. A slower website means higher bounce rates and low conversion rates. Obviously, no one loves to lose potential buyers from the website. You will definitely choose the right image file format that not only makes your site better but also increases its page loading speed. 

Read this guide to learn about the features of PNG and JPG image file format. You will find useful information about the uses, and pros and cons of both of the above-mentioned image file formats. Let’s start it and never make a mistake again!


What is the PNG image format?

PNG “Portable Graphics Format” is the most frequently used uncompressed raster image format on the internet. This lossless data compression format has replaced the Graphics Interchange Format (GIF) because of its reliability and no copy-right limitations. It is simple and open to use. 

Uses of PNG

  • PNG can display transparent background just like GIF images. All the PNG files contain 24bit RGB colour palettes and grey-scale images to enhance the viewer experience. Even you can apply multiple editing effects on PNG files using PaintShop Pro.
  • It offers professional-grade image transparency options. You can add an alpha channel or single-pixel value to create transparency of images. It adds alpha values to palette images.
  • PNG uses a non-patented lossless data compression algorithm to compress images by default. It uses a two-stage compression process including pre-compression or filtering and deflate compression.
  • PNG also uses the Adam7 algorithm to offer an optional two-dimensional 7-pass interlacing scheme. It makes the low-resolution images to be clearer and more visible during transfer.
  • However, PNG does not support animation. You can use MNG ‘’Multiple-image Network Graphics’’ extensions to support the action of animation.


  • Offer lossless compression without sacrificing the quality of images
  • Suitable for editing and storing images
  • Perfect for images containing texts, line arts, and graphics
  • Ideal for transparency and compression of digital images


  • Do not embed metadata used by digital cameras
  • Require extensions to support animations
  • Do not support non-RGB colour spaces
  • Compress images at a larger file size

What is .JPG or JPEG image format?

JPG or JPEG ‘’Joint Photographic Experts Group’’ is a standard image format used for lossless image compression. It maintains the dimensions and quality of the image irrespective of its size. JPG or JPEG is the most popular image format for transferring photos over the internet.

Uses of JPG or JPEG

  • JPG or JPEG compresses images from larger file formats into smaller ones with negligible loss in quality. It contains Discrete Cosine Transform (DCT) image compressing algorithm that checks the pixels and combines them to create a better image.
  • It significantly increases the speed of your website. Moreover, it also allows the users to use different tools for compressing images.
