Ep 6 Bro, how about PNG?

Updated: Dec 12, 2022

Relax, I'm getting into it.

In Wolfpac Productions, we only use JPEG for our photos but when it comes to graphic designing where certain designs has to be done, we do use PNG too!

Let me guide you through it.

To recall what we discussed previously, we touched on JPEG. No, I won't repeat what I went through before this but here are the formats we will slowly touch on in the subsequent posts:

  • JPEG

  • PNG

  • TIFF

  • GIF

  • EPS

  • RAW/CR2/NEF/ORF etc.

1. What is a PNG file?

PNG stands for Portable Network Graphic, and it is a type of raster image file. A raster image file is a rectangular array of rectangular sampled values called Pixels. This file type is popular with web designers as it can handle transparent backgrounds and at the same time this format is not patented, thus, one can open a PNG file without having the need for licensing.

When you save your photos in PNG format, it would end in ".png", and this format has 16 million colours.

2. When was PNG firstly introduced?

Back in 1995, IT expert Oliver Fromme invented PING which was later on shortened to PNG, well either ways, they sound the same.

3. What is the difference between PNG and JPEG?

The difference is between their compression processes. JPEG contains lesser data than PNGs. From the previous post on JPEG, we know that JPEG files are able to compress the files to smaller data but not for PNG files as it retains data, thus storing more information, and this would create bigger files especially when lossless compression occurs. As mentioned earlier, PNG supports transparent background which is ideal for graphic designing, unlike JPEG.

4. Are there any disadvantages of using PNG File formats?

PNGs retain a bigger file size, which would lead to slower loading time on websites. It is also designed for website, thus, it does not support CMYK Colours. It would be an issue if there's a need to print.



Okay, that's enough information for our brains to retain. See you again next year, Happy New Year!
