What is it?
JPG (يكتب أيضًا كـ JPEG - مجموعة خبراء التصوير المشتركين) هو تنسيق ضغط صور مفقود تم إنشاؤه في عام 1992. إنه أكثر تنسيق صورة مستخدم على الإنترنت، وفي الكاميرات الرقمية، وعلى الهواتف الذكية في جميع أنحاء العالم.
يعمل التنسيق عن طريق التخلص من بيانات الصورة التي من غير المرجح أن يلاحظها العين البشرية، مما يحقق تخفيضات دراماتيكية في حجم الملف. يمكن أن يكون JPEG عالي الجودة أصغر بـ 10 مرات من النسخة غير المضغوطة من نفس الصورة مع عدم وجود فقدان مرئي تقريبًا في الجودة.
