What is PNG
A PNG or portable network graphics file is a digital image format commonly used for websites. When it comes to image compression, where data is converted to consume less space than the original file, the PNG format uses lossless compression or minimal quality loss compared to the lossy compression of the JPG (joint photographic experts group) format.
Thomas Boutell is recognized as the man who developed PNG in 1995 when the most popular image file format for the web was the graphics interchange format (GIF). The PNG format emerged as an alternative to the GIF after UNISYS, which held the patent for the so-called LZW compression method for the GIF, decided to require a license for its file format.
PNG’s popularity came from its ease of use, particularly when you need a certain portion of an image in its original colors while the rest stays transparent. This makes it the ideal format for images such as logos, which often need to be placed over another picture.
Why PNG Files Need to be Resized
The PNG format is the best choice when you need to edit an image several times since JPEG images undergo generational loss during repetitive editing and saving.
However, you’ll often need to resize PNG images; they’re larger in file size due to their higher resolution, making websites take longer to load and emails longer to send.
