JNG File Extension

JPEG Network Graphic – file format by PNG Development Group

JPEG Network Graphic (JNG) is an image file format developed by PNG Development Group. It combines the lossy compression of JPEG with the transparency support of PNG, resulting in smaller file sizes while preserving image quality.

JPEG Network Graphic (JNG) File Format

A JNG file is an image file that combines the lossless compression of PNG with the lossy compression of JPEG. It was developed by the PNG Development Group as an alternative to the JPEG and PNG formats. JNG files are typically much smaller than PNG files, but they can still retain a high level of image quality.

JNG files are supported by a variety of image editing software, including Adobe Photoshop, GIMP, and Paint.NET. They can also be opened by most web browsers, including Google Chrome, Mozilla Firefox, and Microsoft Edge. However, JNG files are not as widely supported as JPEG and PNG files, so you may not be able to open them on all devices.

Overall, JNG files are a good choice for storing images that need to be both small and high-quality. They are particularly well-suited for use on the web, where file size is a major concern.

Opening JNG Files with Image Editors

JNG files can be opened using various image editors that support the JNG format. Some popular options include:

  • Adobe Photoshop: A widely used professional image editing software that supports a wide range of file formats, including JNG.
  • GIMP: A free and open-source image editor that supports JNG files and offers extensive editing capabilities.
  • Paint.NET: A free and lightweight image editor that handles JNG files effectively.

To open a JNG file in these editors, simply navigate to the “File” menu and select “Open.” Locate the JNG file on your computer and click “Open” to import it into the editor.

Online JNG Viewers and Converters

If you do not have an image editor installed, you can use online JNG viewers and converters to access and convert JNG files. Here are a few options:

  • JNG Viewer (https://www.jngviewer.com): A web-based viewer that allows you to view JNG files online without any software installation.
  • Zamzar (https://www.zamzar.com): A file conversion service that can convert JNG files to other formats such as JPG, PNG, or TIFF.

JPEG Network Graphic (JNG)

The JPEG Network Graphic (JNG) file format is a raster graphics format designed for efficient web delivery. It was developed by the PNG Development Group as an alternative to PNG and JPEG formats. JNG combines the advantages of both PNG and JPEG by supporting lossy and lossless compression, as well as transparency and animation. This flexibility makes JNG a versatile format suitable for a wide range of applications, from web graphics to print materials.

Technical Details

JNG files are based on JPEG 2000, an advanced image compression standard that provides higher compression ratios than JPEG with similar or better image quality. JNG also supports a number of additional features, including:

  • Lossy and lossless compression: JNG allows users to choose between lossy and lossless compression, enabling them to optimize the balance between file size and image quality.
  • Transparency: JNG supports both alpha channels and transparency, allowing images with transparent backgrounds.
  • Animation: JNG can store multiple frames in a single file, enabling the creation of animated graphics.
  • Metadata: JNG supports the storage of metadata, such as author information, copyright notices, and color profiles.
