Part 4. FAQs about How to Enlarge JPG/PNG

What is the difference between JPG and PNG?

JPG and PNG are all image formats, but their image information encoding methods are different. JPG uses the DCT method for coding transformation, leading to a smaller size; PNG uses a lossless data compression method, DEFLATE, which leads to improved image quality and colors.

What is the advantage of PNG?

As a lossless compression image format, PNG won't discard the data while compressing, maintaining the image quality. Another great advantage of it is that it supports transparency.

Is there any difference between JPG and JPEG?

There are no differences between the JPG and JPEG in terms of their functions and usage. Some editing programs like Photoshop even save JPEG images with the .jpg extension by default. Their only difference is that JPEG has one more character than JPG.
