We are all crazy about social media, spending lots of time to immerse ourselves in Twitter, Facebook, Instagram and so on. Now, take a look at these pages, is that images cover a great part of your pages true?
Definitely. But Why? Because images are simple, we can get the information at a short glance; images are fascinating, adding entertaining elements to information obtaining; the most important is, images are web-friendly, especially those JPEG images, they are small in size which makes the circulation on internet easy and smooth.
While, the PDF files, the most frequently used format to save and share information, fill all aspects of our life. But it is not so web-friendly like JPEGs and cannot be previewed easily for a faster information filtering. So, very often, we need to convert our PDFs into JPEG to post online or email, etc.
What is JPEG?
JPEG, abbreviation of Joint Photographic Experts Group, is the most commonly used format among those image formats attributing to its high compatibility on Web. It is often used for colorful photos or images with various blends or gradients.
What is the difference between JPG and JPEG?
You may be also wondering why there is another extension JPG, which is so similar with JPEG. Actually, JPG and JPEG is the same thing. Back to those days Windows still dominates, Windows requires that all the files should come with a three letter file extension, so the Joint Photographic Experts Group, which should be originally abbreviated as "JPEG", was assigned with the extension of ".jpg". However, there is no such a file extension limitations on Macintosh, Mac users took it as ".jpeg". Now such limitations on file extension disappear in Windows, ".jpeg" is also widely accepted. Both 2 terms ".jpg" ".jpeg", though essentially the same thing, coexist and become the most popular image format.

JPEG2000 is the new standard created by Joint Photographic Experts Group in the year of 2000 as the next generation of JPEG, designed to offer better compression performance with improved image quality. However, decades past, JPEG doesn't hit the mainstream as it was expected. The main reason seems to go to its entirely different format based on new code which causes lower compatibility and more memory to process. However, JPEG2000 has its own followers, also got support from many other sites or applications.
