JPG Vs PNG Comparison – Which is Better? (Quality & Size)

JPG Vs PNG Images

JPG Vs PNG, this is one of the most interesting questions I ever wonder to answer. There are a lot of formats available these days to store your images. JPG and PNG are two of the most popular formats among them. On the Internet, you’ll find most of the images uploaded on websites and blogs in any of these formats mostly. Now, the question is which is the better one and which one we should use for our images? We’ll try to conclude this by the end of this article.

Overview of GIF, PNG, and JPG Image Formats

Before understanding PNG format well, you need to first understand the GIF (Graphics Interchange Format) a bit first.

GIF Format

GIF is a lossless compression file format which is limited to 256 colors. It supports animations and specifically for the purpose of animations, it has been seen to be used worldwide to date. It was also patented. As it uses a lossless compression technique, therefore it is a good format for storing any kind of drawings, graphics or icons. The overall size of the image remains small to be used across the web. For detailed knowledge, refer GIF Wikipedia page.

PNG Format

PNG is a lossless compression file format and is commonly used across the web. PNG is the acronym for Portable Network Graphics. It was initially an improved replacement for the GIF Format which is not patented. It also is good for storing any of the drawings, graphics or icons in a small-sized file. It was published as an ISO/IEC standard in 2004. It’s been 23 years since its release now. It is an open format. Visit PNG Wiki Page for detailed knowledge about the format.

JPG Format

JPG is a lossy file format. In other words, you’ll lose some quality if you’ll save the image in JPG Format. But it really helps in reducing the overall size of the image. Therefore, JPG becomes the first choice of web developers who want their websites to be loaded really fast. Also, it is the most popular image compression format in the world.

JPG Vs PNG Comparision

Now, the major aspect of this article, the difference between JPG and PNG file formats. Which are better and for what reasons?

Well, many of you might have got the answered from the overview sections. Each format as got its own benefits. So, considering the two major factors, Size and Quality, I’ve given the comparison below.

  • JPGs are good if you want better compression but not so high quality.
  • PNGs are good if you want lesser compression but good quality.

In the image examples given above in the JPG and PNG overview sections, you can notice the size of the PNG and JPG formats. The same image in PNG format was 164 KB in size, which reduced to only 34 KB when converted to JPG format with minor quality loss.

Now, the point is which image file format is good for the Internet and to be used on websites and blogs. Well, the most used format all over the world for the web is JPG, obviously due to the fact of better compression. It simply means that JPGs can be served faster across the web. They are smaller in size than PNGs and hence are loaded faster on the webpages.

But if you want your website to show the real quality of images, then you should not use JPGs at all. Prefer PNGs in those cases wherever you want quality. But if you believe, the quality of the image remains unchanged or not so noticeable if you save the image in JPG format, go ahead with it.

These days, there are some tools available online, which can help you reduce the size of your PNG images without losing the quality much. One of such popular tools is TinyPNG.

This tool simply helps you to reduce the size of any of your JPG or PNG images. I use this tool here on WTMatter.com to reduce the size of all of the images that I upload here on the blog and website. Size of some of the JPG, as well as PNG images that I upload here, are reduced by upto 90% using this wonderful tool.

Transparency. PNG images are also good if you want to preserve any kind of transparency in your images. While converting your images from PNG to JPEG file format, you’ll lose transparency.

For Social Media Websites. While writing this article, I researched what people search online related to JPG and PNG images, so I found a lot of people asking which is good file format for social media websites like Facebook and Instagram.

So, basically you should upload high-resolution PNG images there. It’s just a suggestion because I feel social networking sites themselves do some compression to reduce the image file size, maintaining most of the quality.

For WordPress Users. You people need not bother much about JPG Vs PNG, simply install the Compress JPEG & PNG images plugin offered by TinyPNG for WordPress. This plugin will automatically reduce the size of the images that you’ll upload, maintaining most of the quality of image.

Fact. Most of the time the vector graphic images and drawings are stored in PNG format due to the fact of not losing the quality and the realistic images that are captured by cameras are stored in JPG file formats.

In Web Design, you’ve to design everything keeping the page load time factor in mind. As you’re now clear of images, you can also focus on the fonts part. Self-hosted server fonts are usually slow to load and increase the page load times. Alternatively, you can use Google Fonts that are faster to load. We have a tutorial for it and the link is given below.
