JPEG
Extension: .JPG or .JPEG
Meaning: «Group of photography experts»
Date of creation: 1986.
It can display millions of colors thanks to its complex compression french mobile numbers algorithm. This reduces the file size considerably without sacrificing too much quality. It is ideal for web pages .
Format: 16 bits.
It should be used when the lightness of the file is more important than its quality. It is important to note that the human eye does not perceive some color details that can be sacrificed to save space. There are several tools to further compress the format. It is a fact that smaller files mean faster loading and less storage space. They are ideal for complex coloring as well as composite shading of light and dark.
GIF
Extension: .GIF
Meaning: Graphics Interchange Format.
Date of creation: 1987. This format was created by Steve Wilhite at Compu Serve to be able to transfer images quickly over slow connections.
It uses 256 indexed colors. It can be progressively interlaced, where a low-quality version is displayed first and then the details are improved.
Uses lossless color compression. Allows for one-bit transparency, one color can be chosen to be transparent.
Best uses: Web graphics with few colors, small icons, animations, simple images such as line drawings with single-color borders, simple cartoons.
PNG
Extension: .PNG
Simplified: Lossless compression, no low quality.
Date of creation: 1990.
PNG 8: Very similar to the 256-color GIF.
PNG 24: Can have over 16 million colors.
Lossless compression means larger files than your average JPEG.
Alpha Channels: Allows for a translucent looking gradient. All PNG images can be placed over any background and still retain their original appearance.
Best uses: Web images like logos, images mid-print process, complex images like photographs.
