An image file format is a file format for a digital image. There are many formats that can be used, such as JPEG, PNG, and GIF. Most formats up until 2022 were for storing 2D images, not 3D ones. The data stored in an image file format may be compressed or uncompressed. If the data is compressed, it may be done so using lossy compression or ...
A PNG file contains a single image in an extensible structure of chunks, encoding the basic pixels and other information such as textual comments and integrity checks documented in RFC 2083. [7] PNG files have the ".png" file extension and the "image/png" MIME media type. [8] PNG was published as an informational RFC 2083 in March 1997 and as ...
WebP is a raster graphics file format developed by Google intended as a replacement for JPEG, PNG, and GIF file formats. It supports both lossy and lossless compression, [8] as well as animation and alpha transparency . Google announced the WebP format in September 2010, and released the first stable version of its supporting library in April 2018.
Google PageSpeed is a family of tools by Google, Inc. designed to help optimize website performance. It was introduced at a Developer Conference in 2010. There are four main components of PageSpeed family tools: PageSpeed Module (consisting of mod PageSpeed for the Apache HTTP Server and NGX PageSpeed for the Nginx), PageSpeed Insights, PageSpeed Service, and the PageSpeed Chrome DevTools ...
The BMP file format or bitmap, is a raster graphics image file format used to store bitmap digital images, independently of the display device (such as a graphics adapter ), especially on Microsoft Windows [2] and OS/2 [3] operating systems. The BMP file format is capable of storing two-dimensional digital images in various color depths, and ...
Modern displays and printers are raster devices; vector formats have to be converted to a raster format (bitmaps – pixel arrays) before they can be rendered (displayed or printed). [10] The size of the bitmap/raster-format file generated by the conversion will depend on the resolution required, but the size of the vector file generating the ...
Website. jpeg .org /jpegxl (official website) jpegxl .info (community website) JPEG XL is a royalty-free raster-graphics file format that supports both lossy and lossless compression. It is designed to outperform existing raster formats and thus become their universal replacement.
JPEG 2000 (JP2) is an image compression standard and coding system. It was developed from 1997 to 2000 by a Joint Photographic Experts Group committee chaired by Touradj Ebrahimi (later the JPEG president), with the intention of superseding their original JPEG standard (created in 1992), which is based on a discrete cosine transform (DCT), with a newly designed, wavelet-based method.
