Description JPEG (Joint Photographic Experts Group, 1992) is the standard for compressed photographs. A .jpg file stores 8 bits per colour channel and discards the detail the eye is least likely to notice, which makes a 24-megapixel photo 5 to 10 MB instead of 70 MB uncompressed. Every camera, phone, browser and editor reads and writes it.
Benefits Opens everywhere. Small files at good quality. Carries EXIF, IPTC and XMP metadata and ICC colour profiles. Rotation and cropping can be done without re-compressing, with the right tool.
Drawbacks Lossy: quality drops a little with every re-save. No transparency, no layers, 8 bits per channel only. Visible blocking and halos at low quality settings or after many edits.
