Before we start talking about this topic, it is important to mention that there are many different types of image formats (for example, SVG can be used to create Favicon). However, for the purpose of this article, we will analyze two popular image formats: JPG and PNG. These two file formats have both advantages and disadvantages. Consequently, it is essential to know when and how you should use them.
The PNG Format
What is a PNG?
PNG stands for Portable Network Graphics, and it is a file format that is used a lot on the web in general. PNG files stand out mostly because of two useful elements: transparency and its capacity to keep great image quality.
PNG files can be used without a background. It can be helpful if you use your logo on your website, for example. Indeed, unlike JPG image files that automatically come with a background (mostly a white background), PNG files are more flexible and can help you look more professional.
Moreover, you must keep in mind that this type of format has better quality than JPG files. It is because of the fact that the image is compressed differently. Nonetheless, since the files have better quality, they are also heavier. You must then use PNG files when it is only necessary or use an image compressor. Do not forget that the more you use visual elements on your website, the heavier it will be, and it will take more time to load. Your website loading speed is one of the elements that search engines verify when indexing your site.
When should you use the PNG format on your website?
As we just mentioned, the first place we should find a PNG file on your website is for your logo. Indeed, whether it is in the header or the footer, your logo should be present on your site. Since PNG files can have no background, it will be easier to harmonize your logo with the rest of the page.
Using PNG files is also better if you use small images or icons.
The JPG format
What is a JPG?
Let us now talk about the JPG format, also called JPEG. It is an acronym for Joint Photographic Experts Group. JPG files are also used on websites and the web in general. Its most important advantage is that it is an image file format that is less heavy than PNG.
It is true that JPG files always have a background and that they can get blurry easily; however, it is a file format that is perfect for photos or more complex images. We all know that if you have an online store or a website, it is essential to present your products by using many pictures to convince potential customers to make a purchase. You might want to create a portfolio where you can display your best works or add a slideshow with your best travel photos on your blog. When you need to use many visual elements on your website, it is better to use JPG files so it will not harm the web page's loading speed.
Keep in mind that you should avoid playing with JPG files (increasing or decreasing the size, for example) because it will get easily blurry. Please also note that it is likely that you use more JPG files than PNG files on your website.
When should you use the PNG format on your website?
Use JPG files for visual elements with a lot of details or photos. It will allow you to add more pictures while ensuring that your page is not too heavy. Once more, remember that each element you add to your website has a visual weight. Consequently, ask yourself if the picture or photo adds value to your site. Using too many images can create a chaotic effect or distract your visitor from the main purpose of your page.
Since today’s trends regarding websites are related to simplicity, do not attack your potential customers with too many pictures. Use the most attractive and relevant ones. In addition, JPG files are also used on social media.
In conclusion, we hope you now understand better when you should use a PNG and a JPG file on your website. Aim for a PNG file if you need a picture with no background that must be great looking. Choose a JPG file when it is a photo, or you need to add many images to your website. Do not forget that beautiful pictures can help you create a professional-looking website and increase your sales!
