We all know that there are different types of files however we may not understand what the difference is.
In this post I’ll look at:
What is a JPG (JPEG) file?
JPG is short for Join Photographic Experts Group.
JPEG or JPG is a type of lossy compression technique, for colour images. It can reduce file sizes by around 5% or more, however some quality is lost.
What is a PNG file?
PNG is short for Portable Network Graphics.
It is a type of photo compression that will in time replace GIF. Unlike JPG files, PNG is compressed in a lossless fashion so that all image information is restored allowing for higher quality photos than JPG and GIF.
What is a GIF file?
GIF stands for Graphic Interchange Format.
GIF files are compressed in a lossless format however if more than 256 colours are used, there will be a decrease in quality.
GIF files are often used on websites as it allows for transparent backgrounds and moving images.
What is an MP3/MP4 file?
MP3 and MP4 files are both MPEG files, which is short for Moving Pictures Experts Group.
MP3 is short for MPEG-1 Audio Layer 3. It is used for audio and uses a compression algorithm that introduces loss, therefore it’s a lossy compression format.
MP4 is short for MPEG-4 Part 14. MP4 is based on MPEG-4 Part 12 which was in turn based on Apple’s MOV file type. MP4 is a container format, meaning it is used to store audio and/or video data, rather than to code the information. MP4 video and audio can also be streamed over the internet.
