Raster images recorded in JPEG format are known as JPG files and are frequently used to store digital photos and graphics produced by image-editing software. JPEG offers lossy compression that supports up to 16,777,216 colors and can greatly reduce the size of an image without much damage.
The JPEG file format was introduced in 1992 by the Joint Photographic Experts Group (JPEG) to help users more effectively compress and distribute digital photographs. The format’s compression method eliminates certain data from the original image in order to decrease the overall file size and improve transmission efficiency, which has proven crucial for the web in particular.
Although losing picture data reduces the overall quality of the image, the loss is largely undetectable to the human eye. However, professional photographers and graphic designers may choose to use raw files or lossless formats, which are greater in quality and size and require photographs of a higher resolution.
Since its introduction, other technologies have added support for the JPEG format, making it the most widely used image compression standard worldwide. Users can take pictures with their digital cameras and submit them as JPG files to social media sites, make online graphics using image editing tools and distribute them as JPG files, and more.
When to Use Jpg Files when Saving Images
JPEG is the best format for storing digital photos and images that will be published online. The storage space saved typically justifies compression, even if there is a little amount of image deterioration.
Images shouldn’t always be saved as JPG files, though. For banners, booklets, and magazines, for instance, JPEG images are frequently insufficient (TIFF is better). Additionally, JPEG is unsuitable for images that contain text or graphics with sharp edges and does not enable transparency like the PNG format does (both the text and edges get blurred).
Jpeg Files Differ from Jpg Files.
JPEG files are saved in the same JPEG format, hence there is no distinction between JPG and JPEG files. As opposed to Macintosh and Linux systems, previous versions of Windows did not restrict the number of characters in file extensions to three. Due to this distinction, Windows operating systems shortened the JPEG image extension to.jpg while allowing the full.jpeg extension on Macintosh and Linux systems.
JPG files became more prevalent as Windows users increased, surpassing Macintosh and Linux users in number.
JPEG pictures JPG files are still more frequent than JPEG files, even though Windows now supports file extensions larger than three characters.
Opening a Jpg File
Any image viewer will open a JPG file. For desktop and mobile platforms, there are numerous free and paid image viewing and editing programs available, including:
- Google Photos (bundled with Windows)
- iWork Preview (bundled with macOS)
- Affinity Photo (Windows and macOS)
- GIMP (multiplatform)
NOTE: By dragging and dropping a JPG image into your browser window, you can see it in a web browser like Google Chrome (multiplatform) or Mozilla Firefox (multiplatform).
Converting a Jpg File
JPG images can be converted to various formats by a number of picture viewers and editors, including Microsoft Photos, Apple Preview, and Adobe Photoshop.
Microsoft Photos, for instance, may convert JPG files into the following formats:
- Portable Network Graphic (.PNG)
- Tagged Image File Format (.TIF,.TIFF)
- Bitmap Image (.BMP)
- JPEG XR Image (.JXR)
