Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission. Algorithms may take advantage of visual perception and the statistical properties of image data to provide superior results compared with generic data compression methods which are used for other digital data.
Image optimization: Can compresses file size of JPEG images by up to 80% without compromising image quality. It also optimizes high-resolution photos, with a resolution of up to 256MP. Video optimization: The release of JPEGmini 3.3 brought some additional feature of video optimization. Now it can reduce videos by up to 50% while maintaining ...
JPEG XL is a royalty-free open standard for the compressed representation of raster graphics images. It defines a graphics file format and the abstract device for coding JPEG XL bitstreams.
Lossless compression should be used to avoid accumulating stages of re-compression when editing images. Lossy compression algorithms preserve a representation of the original uncompressed image that may appear to be a perfect copy, but is not a perfect copy. Often lossy compression is able to achieve smaller file sizes than lossless compression.
It supports both lossy and lossless compression, and is the preferred image format for Ecma-388 Open XML Paper Specification documents. The format is natively supported by Windows Vista and later as well as Internet Explorer 9, 10 and 11. Third-party support for the format includes Adobe AIR, Affinity Photo, Paint.NET, and Sumatra PDF. [7] [8] [9]
JPEG – a lossy image format widely used to display photographic images, standardized by ISO/IEC; JPEG 2000 – an image format standardized by ISO/IEC; JPEG XL – an image format designed to outperform and replace existing formats. Especially legacy JPEG. Supports both lossy and lossless compression. MNG – moving pictures, based on PNG
Composite image showing JPG and PNG image compression. Left side of the image is from a low-quality JPEG image, showing lossy artefacts; the right side is from a PNG image. In information technology, lossy compression or irreversible compression is the class of data compression methods that uses inexact approximations and partial data ...
For most images without a lot of grain, the two Zip compression methods seem to work best, while the PIZ compression algorithm is better suited to grainy images. The following options are available: [16] None Disables all compression. Run Length Encoding (RLE) This is a basic form of compression that is comparable to that used by standard Targa ...
