Nothing is lost if you open a JPEG file and close it without resaving.Īnother format, PNG, can use lossy compression like JPEG or “lossless” compression that does not lose any data. So if you edit your JPEGs by cropping them, correcting their color, eliminating red-eye in flash photos, sharpening them or making other changes, more details will be thrown away each time you save a new version. To make these files compact, though, the JPEG format compresses image data by discarding picture details (a process known as “lossy” compression), starting with ones that people notice least. It also makes compact files that don’t hog space on a camera’s memory card or take long to download. It’s universal, compatible with all digital cameras, all photo software and all commercial print services.
