When creating a website, you need to make sure that you use JPG and PNG images in the correct context. But what is the difference between the two and which one should you use in your design are questions that will be answered here.
PNG stands for Portable Networks Graphics and unlike the 8-bit limitations of the GIF file type, it offers 24-bit color. This was a breakthrough in the mid-1990s.
PNGs were able to present a collection of colors and shades, with high resolution through lossless data compression. Now, the PNG files can run up to 48 and even 64 bit.
Just as PNG is still widely used, so is JPEG in web publishing. The JPEG or JPG file format was launched prior to PNG in 1992 and its development dates back to 1986.
Images files have a lot of data. Much of this visual information is useless. JPGs are compressed by averaging the color information and reducing the amount of redundant data. This type of compression is called lossy.
JPGs were also a great alternative to GIFs. They can better capture complex images, and compressing them to manageable file sizes with better resolution than GIFs.
Lossless Compression reduces the size of the file while maintaining its original quality. Loss offers a high level of file size compression but affects the image quality.
PNG is a lossless image type, which means that the PNG files that undergo compression are almost identical to the original images. Although PNG files have been compressed, they are still much larger than files that use lossy compression.
Lossy compression squashes files by shrinking redundant data. With the elimination of redundancies, image information is sparse, resulting in very small file sizes. The JPEG format uses lossy compression.
With little data, the image quality can suffer, but the average person scrolling through a website does not check every pixel. The choice of jpeg or png files depends on the content of the images.
As mentioned above, PNGs can have transparent backgrounds. This makes them very useful in a variety of web design contexts.
They are also a great image format for reproducing vibrant colors and making sure lines are sharp, giving PNG a preference for typography, logos, and illustrations.
There are websites that offer
downloads which can be used on projects without the hassle of licensing or copyright infringement. Thus, getting hold of PNG files is easier than ever.
PNG is a great file format for wireframing with lots of text and straight lines. They also work great for screenshots. PNG will hold on to its quality despite being compressed.
However, a web design filled with PNG files will load much slower if you use JPEG. A page that does not load quickly can hurt a website's SEO, as well as make people bounce as it can be frustrating waiting for images to appear.
JPEG files are best suited for images that would otherwise be too large without compression. Images that have no transparent background, many different colors, and details, such as photographs, work best for a JPG image file type.
However, if you want your images to have a transparent background, you need to use a PNG file, since JPEG files always have a flat background color.
