Reducing the size of a file by sacrificing a portion of its data, leading to a smaller size yet reduced quality.	Reducing the file size of an image while preserving its quality and visual information.
A widely employed standard for compressing images which uses lossy compression techniques to decrease file sizes.	Reducing the size of data without any loss of information.
A file format employing lossless compression to store images, often utilized for web graphics and images that have transparent backgrounds.	A lossy compression format used to compress animated images.
A data compression technique that assigns shorter codes to symbols that occur most frequently in a data stream.	The number of bits that are processed or transmitted per unit of time, typically measured in bits per second (bps)

Compression	Data
Image Compression Artifacts	Blockiness
Color Bleeding	Noise
Ring Artifacts	Posterization

Facts or information that is represented in a form suitable for processing.	The process of reducing the size of data by encoding it in a more efficient representation.
Visible grid-like patterns that result from dividing images into blocks for compression	Unintended visual distortions or anomalies that occur in compressed images
Random variations or distortions introduced in an image during compression	Blurring of colors or bleeding of colors outside their boundaries in a compressed image
Reduction of smooth gradients in an image to distinct bands of color due to compression	Circular or ring-shaped distortions that occur around edges in compressed images

	Jagged or stair-stepped appearance of diagonal lines in compressed images
