JNG File

File extension .JNG
CategoryImage File
DescriptionJNG (JPEG Network Graphics) is a raster image format that was developed as an extension to the JPEG (Joint Photographic Experts Group) format. It was designed to address some of the limitations of JPEG, such as the inability to support alpha channels and lossless compression.

JNG files are composed of a JPEG-encoded image data stream and an optional alpha channel encoded in the PNG (Portable Network Graphics) format. This allows JNG files to store high-quality images with transparent or partially transparent backgrounds, which makes them well-suited for web design and other applications where image transparency is important.

JNG files can be created using a variety of image editing software, such as Adobe Photoshop, GIMP, and CorelDRAW. They can also be viewed using a range of applications, including web browsers, image viewers, and editing software.

However, JNG is not as widely supported as other image formats such as JPEG, PNG, and GIF. This means that some applications may not be able to open or display JNG files, and web browsers may not be able to display them without additional plugins or software. As a result, JNG has not gained widespread adoption in the image editing and web development communities, and is generally used only in specific contexts where its unique features are required.

PNG File

File extension .PNG
CategoryImage File
DescriptionPNG images provide lossless compression, that is why the quality of the picture is nice, but the size of the file is huge. Because of it this file format is used by photographers. PNG may have several layers of transparency and even include short text descriptions which help search engines to examine the file. Although PNG was developed to replace GIF and partly other formats, it doesn’t support animation since it can’t contain several images like GIF.
