What is a PNG file?

A PNG, or portable network graphic, is an image type that’s commonly used in web design to offer a clear background and/or a semi-clear image.

PNGs are often used to design logos as the image may be easily positioned over a background of a picture, block of colour or pattern. PNGs tend to be a lot larger than different image file types, corresponding to JPG or GIF, and so it’s usually a good suggestion to limit their use unless you could have a big storage capability or a decrease-finish PC.

However, it is best to use PNG if you happen to’re after probably the most detail as doable in an image. They also assist both 24-bit RGB and 32-bit RGBA colour areas, as well as grey scale, but aren’t designed to work with CMYK modes and, as such, aren’t the very best when coping with printed materials. Again, because of the wider range of support colour spaces, this additional contributes to the file dimension of a PNG.

PNGs are also far more simply accessible in terms of copyright, as they exist as an open format and may be more widely used without the necessity for a licence.

The GIF file type has virtually been entirely changed by PNG within the publishing world, although GIF stays a highly popular format for moving images given its means to compress down file sizes. Nevertheless, even with moving images there are now higher codecs to GIF, equivalent to multiple image network graphics (MNGs).

In October 1996, the first iteration of the file format was created, with additional variations released in 1998, 1999 and 2003, when it turned a global standard.

When to use a PNG

PNG recordsdata can sometimes be larger than a GIF and so it’s worth considering whether or not the file format is definitely the best option for the use case.
