Vector Based File Extensions
.ai: Short for Adobe Illustrator, this file is commonly used in print media and digital graphics, such as logos.
.eps: EPS is an acronym for Encapsulated Postscript, a vector file type that saves and stores images, text, and designs so you can reopen and reedit them at any time.
.pdf: The Portable Document Format is built for the exchange of documents across platforms, if the original file was created in vector format the pdf file will retain the design elements for us to use.
.svg: The Scalable Vector Graphics format is based in XML (a mark-up language used widely across the Internet that's readable by both machines and humans). It’s useful for the web, where it can be indexed, searched and scripted.
Pixel Based File Extensions
.jpeg: JPEG stands for Joint Photographic Experts Group, an international organization that standardized the format during the late 1980s and early 1990s. It’s the go-to file format for digital images.
.png: PNG is short for Portable Network Graphic, a type of raster image file. It’s particularly popular file type with web designers because it can handle graphics with transparent or semi-transparent backgrounds.
.psd: PSD files are the native file format of Adobe Photoshop. It can store multiple layers, images, and objects, in high resolution PSD files can support up to 30,000 pixels in height and width, giving these files an impressive range for both image depth and color spread.
.svg: A TIFF, which stands for Tag Image File Format, is a computer file used to store raster graphics and image information. A favorite among photographers, TIFFs are a lossless form of file compression, which means they’re larger than most but don’t lose image quality.
You can turn a .jpeg into a .pdf with Adobe Acrobat but this is just changing the extention of the file. It doesn't change the quality of the file, it will still be pixel
