Images with clean edges and lines will lose some of their sharpness in the compression. Lossy compression may be a space-saver, but when dealing with very heavily compressed images, the quality will suffer.Post-processing is easier because white balance and saturation in JPEGs are set with the click of the shutter.Compared to lossless formats like GIFs, JPEGs are dramatically smaller in size. By intelligently discarding all the colors that the human eye can’t pick out - called lossy compression - JPEGs keep their file size as small as possible. Their small file sizes allow for quick transfer and fast access for viewing online.JPEG files are arguably the most universally recognized image file format - compatible with most browsers, software, and apps.But this file format is still very much a mainstream favorite. Serious photographers still shy away from shooting in JPEGs because they want to keep all the image detail for post-processing or printing. The real value came in the JPEG’s ability to store metadata - such as where and when a picture is taken, and even camera settings. Now, anyone could snap and store images in small enough files to fit on limited camera storage while displaying reasonably well. JPEG files came into their own with the advent of digital cameras and the World Wide Web. They came up with the concept of lossy compression, which removed visual data that the human eye couldn't see and averaged out color variation. That’s when a group called the International Organization for Standardization (ISO) started working on ways to bring photo-realistic pictures to small screens around the world.Īt the same time, the Joint Photographic Experts Group (JPEG) arrived on the scene and created its own standard to compress graphics files enough to work on the average PC. In 1986, monitor technology couldn’t produce on-screen graphics.
