What is a .JPEG File
JPEG is the overall most common file format for photo storage, email graphics and large web images. JPEG images are great for compressing high resolution files for faster loading and sharing.
What is a .JPEG image file?
Compressed image file:
JPEG images can scale compression that can decreases file size exponentially, but increases pixilation the more the image is compressed. To put simply, high compression will make the file size smaller but quality will be lost.
Raster:
Raster Image files contain pixels. Hi and lo resolution raster images are made up of colored pixel squares that create the image. Learn more about Raster Images here.
Lossy Compression:
Lossy or irreversible compression means when saved as (in this case) a .JPEG, the image will lose some quality that cannot be reversed.

What are .JPEGs used for?
JPEG/JPG are typically used for photos, sharing graphics and large web images like banner ads.
Printing: High resolution files with low compression, JPEGs are perfect for editing and then printing.
Online: JPEGs offer you the most flexibility with raster editing and compression making them ideal for web images that are easily downloaded.
Sharing: JPEG images can be reduced to very small sizes making them great for emailing.
