There are about 30+ formats, but lets focus on jpeg, bmp, & png. I'll go from worst to best.
jpeg is not good for graphics at all. Ever the highest quality jpeg brings noise and sometimes blur to your graphic. (highly not recommended for graphics.)
bmp or bitmap is good for graphics, no blur or noise. It's clear down to the pixel. The problem with bmp is that the coding is very long. 2 - 70+ times larger of a file compared to a jpeg. (Not really recommending this for graphics.)
png or Portable Network Graphics is the ideal file format for graphics. png is as high of quality as bmp, but it can even have transparency in it. Transparency is needed for mostly all graphics. Also png is half to a third less coding than jpeg format. (Highly recommended for graphics.)
There are hundreds of possible formats for graphics. Some common formats are JPG, GIF, TIF, and many more.
The theme, or style, is a set of unified formats for fonts, colors, and graphics.

JPEG file format which have .jpg or .jpeg extension at the end of file name.
The types of file formats found on computers ranges into the hundreds, if not thousands. Specific types of files such as documents, webpages, graphics and photos all have their own file formats with varying extensions depending on the program used to create, open or view each individual type of file. A few common file formats for documents are: .doc, .docx, .txt and .pdf. A few common file formats for graphics or photos are .jpeg, .gif, .png, .eps and .tiff.
The header file of graphics in TurboC is graphics.h
The most popular image/graphics file formats are: .Jpg, .PNG, and .Gif. PNG and Jpg are normal images while .Gif files can be short animated images.
Windows Metafile (WMF) is a graphics file format on Microsoft Windows systems. It is mainly a vector image format, but can also include raster graphics. The format was originally designed in the early 1990s but not commonly used after the rise of the Internet and the widely used graphics formats such as GIF and JPEG.
.EPS, .AI, and .SVG.
GstarCAD can export: DWG, DWF, PDF, WMF, BMP, EMF, SVG and OCF file formats. You can also open and save DXF, JPEG, TIF, PNG, GIF file formats.
