New Generation Image Format: BPG

| Multimedia · News

Since 1994, JPEG has become a standard and still is being considered the most popular image format. Can JPG be dethroned after 20 years of ruling? With BPG it seems possible.

JPEG (Joint Photographic Experts Group), is the most commonly used file format for transmitting images over the internet and for storing photographic images. Because the size / quality ratio is much more successful than many other formats On the contrary to 8 bit color depth supported by the GIF format, JPEG has a 24 bit color depth. Although JPEG falls behind PNG format in terms of image quality, the lightness of JPEG’s file size made it the most preferred image format through the years. It’s acceptable image quality and it’s light file size, which put less burden on web pages, were the main reasons which kept it on the top.

Emerging technology is changing our life standards in many fields. Mobile phones, tablets, laptops / desktops are developing with a hard to follow acceleration. Just like in many fields of technology, for informatics also,quality is becoming a standart, not a luxury. How many of us still watch the VDCs, which were a big part of our life in a not far past, at their wide screen televisions? This video format which has a 325 x 288 pixel resolution cannot compete with the quality of HD, Full HD technologies, which are becoming a standard of the field. It would not be visionary to think that today’s luxury formats like 4k, 8k will become standard formats in the near future.

By comparison with the rapid ascent of video formats, image formats still didn’t achieve this technological leap. French programmer Fabrice Bellard probably asked himself “Why can’t digital images have less file size with higher image quality?” thus in 2014 he introduced a new digital format, BPG (Better Portable Graphics) to the world. What BPG promises seem more appropriate to today’s standards compered to JPEG. BPG’s file size is lighter than JPEG’s and BPG’s image quality is obviously better. Another superior feature of BPG is it’s alpha channel information support. At this point we can easily say that BPG is also competing with the PNG format. Although PNG also supports alpha channel, its low compression ratio is putting extra burden to web pages and mobile devices. Looks like a great deal of this burden will be relieved with BPG.

BPG format is very new at the moment. It seems it’s in the hands of the users for BPG to become widespread. However, the possibilities it offers, already excited many of us.
