Updated on February 17, 2016, as the most widely used image format and standard format for image compression in the world, we are all familiar with JPEG. But it’s far from perfect. Based on more than 20 years of JPEG loyalty, is it time to need something new? Of course, there are well-known GIF and PNG file formats, each of which has its own popularity. However, GIF is suitable for logos, icons and small animations, but not for high-resolution photo quality. Png performs well in photo color, quality and transparency, but the compression is insufficient. The question is, can we combine the advantages of JPEG and PNG and look forward to a new standard to improve the defective image format?
BPG (better portable graphics card) and BPG created by personnel programmer Fabrice balland in 2014 have great potential to replace JPEG due to the improvement of quality and file size. This post introduces the comparison between BPG and JPEG. Check the strengths and weaknesses of the form and whether JPEG needs to be replaced. Exact description of BPG format. BPG provides and how these functions improve the disadvantages of JPEG. The obstacle related to BPG is the image compression standard, which is a real substitute. Do you need to replace JPEG? The standardization of JPEG can be traced back to 1992. It has really helped in the past 20 years. By today’s standards, this is a good compression format. Therefore, this is not enough to replace JPEG.
But is it really good enough? The saturation of the web is 1 billion times higher than that in the 1990s. In 2016, should the digital image be better than the simple fit? The improvement of JPEG standard can bring great convenience to photographers, designers, developers and end users. The problem is that by improving the web and making it better, a new BPG format has emerged. But first, let’s look at the notable shortcomings of JPEG. Problem #1: quality and file size one of the benefits of JPEG compression is that it can be controlled. But here, we will encounter a major compromise.
Web takes image as the center and has a high demand for high-quality visual effects. If you want to present wonderful images with JPEG on the web, you only need to use very little content in compression. Of course, with the improvement of image quality, bandwidth usage will increase and loading time will decrease. In other words, it’s a little difficult to make JPEG look flawless. Question 2: if old technology still solves problems in an effective way, the era of technology is not important. But here, the problem is that with the evolution of the web, the expectation of vision and function has increased dramatically. Quality is important, but speed is also important. Due to its shortcomings and non open source, the development of JPEG is almost stagnant, while the surrounding digital world is changing all the time.
Problem #3: PNG has no transparency function. It not only provides advanced transparency and excellent photo quality, but also provides suitability with monochrome areas such as signs and icons. It is a beautiful file format. Unlike PNG format, JPEG does not provide transparency. However, when PNG is used for high-resolution photos, there is often a file size problem. In many cases, its size is larger than JPEG. PNG is superior to JPEG in many ways, but it cannot compete with it in file size. Therefore, neither option is ideal. What can BPG provide that JPEG can’t do? We can see the main defects of JPEG. Now, let’s take a closer look at this fantastic new image format BPG.
BPG format is very young. Fabric bellard (also the founder of ffmpeg software project) mentioned earlier invented BPG image format especially to replace JPEG.
I did. Is BPG really improved by JPEG? Let’s see what it provides. Advantage #1: double quality. BPG provides better image quality and file size than JPEG. In BPG format, you can have an image of the same quality in an image of the same size as JPEG but twice its quality or in an image of half its size. This is a very important point of sale and the main reason why beallard originally created the format. Since most of the websites you usually visit use JPEG, BPG is likely to be a very broad solution to online image quality and file size problems.
Advantage #2: transparency Maleis that BPG format provides transparency. This is another advantage over JPEG. Png also provides transparency, but BPG has impressive compression and transparency. Advantage #3: BPG based on HPEC is based on HPEC, which is twice as efficient as the previous version (H.264). This means that the encoding process is more efficient than JPEG, so better results can be obtained. In addition, smartphones and tablets do not require special hardware to encode and decode BPG. Hevc support has been included in most advanced models since 2014.
Advantage #4: it is open source, and the decoration of this enhanced image format is open source. Unlike JPEG, if BPG becomes the image format standard, BPG will not become obsolete or improved over time. Keep fresh through community contributions. Therefore, the advantages of BPG are obvious. What is catch? BPG is a suitable candidate for JPEG replacement. But there are problems. Insufficient batch adoption. It will be extremely difficult to launch a solution to push popular image formats such as JPEG off the throne. About 700 million websites use JPEG. BPG will run on JPEG if there are a large number of initial use waves. The problem is that BPG only runs on websites that use the 56KB JavaScript library currently created by belland. All popular web browsers require built-in support to gain the opportunity for widespread use and standardization of formats. Developers should use and recognize BPG, not JPEG. BPG (currently) does not exist.
BPG to JPEG: conclusion how JPEG provides excellent but not impressive results, and there is no transparency function, there is obviously an absolute alternative space. After more than 20 years of use, converting to an efficient BPG format looks simple. However, BPG provides better quality images and more compressed file sizes, and there is still a lot to do. Therefore, please carry out the test. Use BPG on the website. Notify other webmasters, developers, or photographers. Share your views in photos and online communities. More attention is paid to this format, which is very important for the development of image quality.
Have you ever used BPG? Does the form meet your expectations and propositions? Please tell the following comments!
