Understanding File Types and Image Formats

The video tutorial explains the importance of file extensions and distinguishes between raster and vector images. Raster images, made of pixels, can lose quality when scaled, with JPEGs being the most common type. Vector images use mathematical equations, allowing them to scale without quality loss, with EPS and PDF as common formats. The tutorial advises using vector formats for printing to maintain image quality.
