some notes on file formats

GRAPHIC FILE FORMAT

File Formats

-all computer docs are packaged in different formats

-format is determined usually by file origin

-graphic files (video, image) can be reduced in file size by using image compression formats

Lossy vs. Lossless

-Lossy: Image data is “lost”/reduced for smaller file sizes, causes poor image quality

-Lossless: retains all image data but results in large file size, does not compress image

GRAPHIC FORMATS

-TIF, JPG, and GIF are 3 most common formats, used for printing, scanning, and displaying images on web

-PNG is a common web format and can contain a transparency channel
