GIF, PNG, RAW and BMP are all lossless image formats.ĭigital cameras compress raw photographs as JPEG images to make the files smaller in size. Lossless compression refers to compression in which the image is reduced without any quality loss. This format is suitable for file types in which lost details are hardly perceptible. Lossy compression involves permanently removing unnecessary metadata from the image file to compress it. Images saved in the JPEG file format take up 50-75% less disk space, reducing the time needed to load, transfer or download them. Data compression is the act or process of reducing the size of a computer file. JPEG is a lossy compression method used to ensure the digital images being used are as small as possible and load quickly when someone wants to view them. The term JPEG stands for three different things: 1. JPEGs are modern image formats that allow for convenient internet usage and have a variety of features to make them optimal for posting and high-speed uploads and downloads.

While this image quality loss is relatively unnoticeable, this shared quality is why both image file types are best viewed within their original source location, rather than as a saved image. Every time a user saves an image, the pixel transfer from the source location to storage shrinks, meaning that each pixel shrinks as well. Image quality lossīecause both JPGs and JPEGs use pixel-based imaging programs, the files eventually lose quality over time with each transfer. Due to their pixel-based imaging system, both file types show lower quality if a user enlarges the photo too much. Because they use raster imaging, both JPGs and JPEGs are optimal for nonlined, subtly-hued images such as logos, intricate art and high-density photos. This process uses pixels as individual points to create an image. Some more similarities between JPG and JPEG file formats include: Raster imagingīoth JPG and JPEG image formats use the pixel processing program raster imaging.

If you have files with either extension that your image viewer or editor can open without issues, there’s no need to convert JPGs to JPEGs or vice versa. Nowadays, newer versions of Windows now accept file extensions that have more characters and most apps understand and open both JPG and JPEG files equally. UNIX-like operating systems like Mac or Linux never had this limit. JPG exists because the earlier versions of Windows operating systems had a maximum 3-letter limit when it came to file names. The term JPEG is an acronym for the Joint Photographic Experts Group, which is the name of the International Organization for Standardization (ISO) subcommittee that helped create the standard in 1992. jpg, and JPEG files are saved with the file extension. JPG files are saved with the file extension. The only difference is the number of characters used. JPG and JPEG are two equivalent file extensions that both refer to the same digital image format, so there are actually no differences between the JPG and JPEG formats. In this article, we compare JPG and JPEG file formats and explore the details of both image file formats. JPG and JPEG image files are similar file formats that are among the most popular file formats used by businesses and departments that use media. When creating a website, adjusting a media post or preparing a memo, understanding the significance of image files can improve your overall work quality.
