Part 3: PNG Vs JPG?

a. Differences Between PNG and JPG

There are a number of differences when it comes to PNG and JPG format and there are a number of factors that need to be considered when choosing between PNG or JPG.

Quality: The major difference between both the format lies in their compression method. PNG format supports lossless compression whereas JPG supports lossy compression and thus the quality of JPG file is low as compared to that of PNG. With lossy compression, the size of a JPG size is smaller as compared to that of a PNG file.

The JPG format is suitable for use in photographs and images having lots of colors while a PNG file is best for transparent images, images with text and with line art. JPG does not support indexed color while PNG supports it for 1-8 bits.

b. Choosing Between JPG and PNG

1. PNG vs JPG for Web

When it comes to using of images on your website, blogs, and other sites, JPG works as a better option. Offering 10:1 compression ratio, JPG can reduce the file size considerably and thus the reduced data amount of image further makes the site responsive as the designs are loaded faster on the website. So when it comes to PNG Vs JPG size, the latter is the preferred choice.

On the contrary, if you want to use an image that features graphics, line drawings, or textual graphs on your site, PNG will be a better choice. Sites that use logo designs, transparent background and pictures with fade effects use PNG as their format.

Thus when it comes to the web, a combination of JPG and PNG can be used.

2. PNG vs JPG for Print
