.jpg — JPEG Image
Joint Photographic Experts Group · 1992
Qu'est-ce qu'un fichier .jpg ?
JPEG (Joint Photographic Experts Group) is the most widely used image format on the internet and in digital photography. It uses lossy compression to dramatically reduce file sizes while maintaining acceptable visual quality. JPEG is ideal for photographs and complex images with smooth color transitions. However, each time you save a JPEG, it loses some quality due to re-compression, making it unsuitable for images requiring frequent editing.
