The Difference between GIF, JPEG and PNG

The JPEG format was created to be used with photos. The GIF and PNG are competitor formats that support lossless knowledge compression.

There are different image file formats today and it pays to know what they are. They are the standardized method of organizing, managing and storing your image files. When it comes to compressing the images, there are two techniques that are often used. The first one is lossless, which is utilized to reduce the size of the image without worrying about the quality of the image. The lossy compression takes advantage of the fact that the naked human eye cannot discern everything that is in the picture. This is why it discards any information that is invisible to people. Now, there are three main graphic file formats and they are the JPEG, GIF and PNG.

JPEG

The JPEG format is mostly used in websites to show photos or realistic art that have a smooth transition between colours. Text, logos or trendy art that has sharp colour distinction produce visible artefacts that do not look visually appealing. JPEGs usually save photos at the best quality in relation to file size.

Also, the JPEG format loses thus me data when you save the image as a result of it uses a lossy compression so it’ll lose some visual quality. The answer is to edit the file with a lossless compression system and only save the ultimate image as a JPEG.

GIF

GIF’s is that the other original major player in the web image format realm. GIFs are best suited to images that do not need many colours as GIFs only support a limited 256 colour palette. Logos, Banners and sprites are common uses of GIFs as they typically use many solid colours.

Gifs/Memes have a lossless knowledge compression system thus it’s helpful for resizing images. It’s usually a nasty option to use GIFs for photos because it needs the use of video digitizing (a method that makes colours not available in the 256 GIF colours by overlapping totally different coloured pixels.) This makes for a huge file size once dealing with pictures that have a lot of variants in colour.

The other options that create GIFS well-liked are its transparency and animation options. GIF are the sole well supported format for animation and remains the foremost usually used image format for transparent pictures.

PNG

The PNG format may be a comparatively new format that’s currently completely supported by the majority major browsers. PNGs directly compete with GIFs and are usually a better image format that uses less space and has alpha transparency channels that allow partial transparency additionally to the GIF’s full transparency. PNGs are also not restricted to 256 colours. The sole major advantage GIFs have over PNGs is animation capability.

Many designers retreat from the PNG format as a result of others tell them that it’s not supported by several older browsers together with IE6 and below. This is often solely true for the alpha transparency feature. All the options offered by GIFs, together with full transparency, are supported for the PNG on older browsers also as newer ones. Additionally, older non-IE browsers have alpha transparency rendering capabilities and also the latest internet human offers full support too.
