Question 1

What does JPG stand for?

Accepted Answer

JPG (or JPEG) is a file type designed to minimize the file size of photographs to make it more suitable for sharing and using in web design. In other words, JPG files are web-friendly because such files are typically smaller. JPG or JPEG stands for Joint Photographics Export Group, the group that developed it.

Question 2

What does PNG stand for?

Accepted Answer

PNG is an acronym for Portable Network Graphics. The image format is optimized for graphics like graphs, logos, and text, but you'll often will notice higher quality than a JPEG with photos as well. PNG is usually used in web design to provide a transparent background or image.

Question 3

What's the difference between PNG and JPG?

Accepted Answer

The key difference between JPG and PNG has to do with the tradeoff between file size and quality. JPG is considered a "lossy" format, meaning that as you increase compression (and file size), the quality of the photograph decreases. PNG was designed as a "lossless" format, meaning that it attempts to compress the file without a loss in quality. Because of this, you can generally achieve much smaller file sizes with JPG vs. PNG, but will need to balance size and quality.

Question 4

Is JPG or PNG better?

Accepted Answer

JPG images are usually smaller files, and thus experience quality loss because of image compression. PNG images are larger files and don't experience as much quality compression. Both image file types have their advantages and disadvantages depending on their application. Converting to PNG is often the best thing to do if you plan on editing photos since they have no quality loss. On the other hand, converting to JPG is preferrable is you don't plan to edit the image, but you look to optimize it for web.

PNG is an extremely common image size, so most image viewers will open them. In Windows you can open PNG files with Windows Photo Viewer. Use Preview if you are a Mac user. All specialized photo editing software will open PNG files easily, if the PNG file is not corrupted.
