Compression artifacts refer to the visible distortions or imperfections that can occur in digital images due to the process of data compression. This technique is used to reduce the file size of an image by removing or approximating certain information, often with the goal of achieving a balance between visual quality and file size.The most common types of compression artifacts include:1. Pixelation: This is characterized by the appearance of visible squares or blocks in the image, caused by the division of the image into smaller, discrete sections during the compression process.2. Blurring: Compression can result in a loss of fine detail and sharpness, leading to a blurred or softened appearance, particularly in areas with complex textures or edges.3. Banding: This refers to the appearance of distinct, visible bands or gradients in areas of the image that should have a smooth transition, such as skies or gradients.4. Noise and Artifacts: Depending on the compression algorithm and settings used, the image may exhibit visible noise, distortions, or other artifacts that can detract from the overall visual quality.The severity of compression artifacts can vary depending on the type of image content, the compression method used, and the degree of compression applied. High-quality images intended for professional use, such as those used in print media or online advertising, are particularly susceptible to these issues, as any visible distortions can undermine the intended visual impact and effectiveness of the content.
Compression Artifacts can be particularly problematic for images that are intended for professional use, such as those used in print media or online advertisements. These distortions can undermine the quality and effectiveness of the visual content, making it less appealing to viewers and potentially detracting from the intended message. Understanding the causes and impact of compression artifacts is crucial for anyone working with digital imagery, whether as a photographer, graphic designer, or content creator.
