File format information for SUN and JPEG

Extension	SUN
Full Name	SUN Rasterfile
Type	Image
Mime Type	application/octet-stream
Format	Binary

The SUN file format, developed by Sun Microsystems, is an image file format used to store raster images in a simple binary format. SUN files are primarily used for high-quality graphics; however, due to the uncompressed nature of the format, SUN files can become very large at higher resolutions.

The format stores image pixel data as a sequence of bytes and supports monochrome and full color image formats in an uncompressed form, meaning there is no loss in quality when saving an image in the SUN format.

SUN files are a legacy file format that can be opened with certain image editing applications that still support this format; alternatively, we have a set of SUN image conversion tools designed to convert SUN files to other, more modern formats, such as PNG.

Extension	JPEG
Full Name	Joint Photographic Experts Group
Type	Image
Mime Type	image/jpeg
Format	Binary
Opens With	Paint.Net, Photoshop

A JPEG file is a compressed and highly efficient image file format whose aim is to store photographic-quality images using a fraction of the storage space compared to other lossy and non-lossy image compression methods available at the time.

The compression used by JPEG encoders is "lossy", meaning image colors that are not perceptible to the human eye are discarded during the compression process. The removal of this color data greatly reduces the size of the final JPEG file with no discernible loss in quality.

Due to their compact and high-quality format, JPEG files are one of the primary image formats used by websites, digital and phone/tablet cameras, and more. This widespread support means JPEG files can be edited within most popular image editing software.
