What Does JPEG Mean?
JPEG (sometimes styled "JPG") actually stands for "Joint Photographic Experts Group." Huh? Yep—it's an actual group.
According to the JPEG website, "The Joint Photographic Experts Group (JPEG) committee (ISO/IEC JTC 1/SC 29/WG 1) has a long tradition in the creation of still image coding standards."
The site also explains that the group usually meets four times a year "to discuss and create the standards for coding of digital representations of images."
What Is the Meaning of a JPEG Image?

TechTarget further explains that a JPEG is "a graphic image file compressed with lossy compression using the standard developed by the ISO/IEC Joint Photographic Experts Group."

JPEG vs. PDF: What's the Difference?
Both JPEGs and PDFs can stare and share images, but they have differences between them. For example, Adobe explains, "The primary use of JPEGs is for images, whereas PDFs can handle all sorts of text and image-based documents. Because JPEGs compress image data, its file sizes tend to be relatively small. This means that it’s a convenient way to share digital images over the web and email."
Also, if there is text on a PDF, you are able to copy and paste it elsewhere. However, you do not have that capability with a JPEG.
How Do I Convert a Picture to JPEG?
If you have a picture that's in another file format, open it up in Preview, go to "File," and then either click "Save As" or "Export." When the next screen pops up, there should be a drop-down to change your image format to a JPEG.
