1- Vector graphics
Vector graphics are small graphics that use math to display images. They can be enlarged without losing quality and are essential for cross-platform designs (i.e. billboards, business cards, etc.).

2- AI
AI stands for Adobe Illustrator document. This is a file format developed by Adobe Systems to represent single-page vector designs.

3- EPS
EPS stands for Encapsulated Post Script. This is a resizable file format that is commonly used for vector designs. Due to its high quality, it’s commonly used with print elements such as logos, business cards or brochures.

4- PDF
A PDF is a Portable Document Format developed by Adobe that can be universally downloaded and viewed by any computer. PDFs are most suitable for sharing previews of work and are universally viewable.

5- Raster graphics
Raster graphics are composed of pixels on a grid, where each pixel is assigned a color value. They are good for assigning special effects, color correction and manipulating photos. They are resolution-dependent, which means that images cannot be enlarged without degrading their quality.

6-GIF
GIF or Graphics Interchange Format is a raster file format that supports animation and transparency. GIFs can only display up to 256 colors, allowing for very small file sizes. (PS: It’s pronounced, “JIF” as opposed to the widely-accepted pronunciation, “GIF,” according to GIF creator, Steve Wilhite.)

7-JPEG
Joint Photographic Electronic Group is also known as JPEG, the most widely used raster file type for web-based designs. JPEGs are compressed files that load quickly. You’ll typically see them used for emails, banner ads, online photos, and pretty much anything else online. Unlike GIFs, they cannot have a transparent background (a white background will be added automatically).

8-PNG
PNG stands for Portable Network Graphics, a web-based format that does not lose quality when compressed. PNG files were created to improve on the quality of GIF files.

9-PSD
PSD or Photoshop Document is the uncompressed working raster image file created by designers in Adobe Photoshop.

10- TIFF
TIFF stands for Tagged Image File Format, a common format for exchanging raster images between applications. TIFF produces a higher quality image than a JPEG or PNG, and is widely used among publishing industries and photographers. Don’t confuse it with a “tiff” or a “rift,” which happens when you send your designer eight rounds of revisions.
