TV ve multimedya amaçlı görüntülerde, 24 bit renk derinliğinde tercih edilir, masaüstü yayıncılıkta tercih edilmez. JPEO tabanlı, diğer grafik ya da görüntü formatları ise JFIF, BSI, RAW JPEG, STORM, PICT-JPEG'tir.

    .JPE ==> JPEG/JIFF Image
    .JPEG ==> JPEG (Joint Photographic Experts Group. Kullanımı en yaygın kayıplı bir görüntü formatıdır. Genelde Web için görüntü alınırken, özellikle renk geçişlerinin öenmli olduğu görüntüler için kullanılır. Diğer pek çok görüntü formatlarıyla karşılıklı çevrime uğrayabilir. Temelinde, sıkıştırma prensibi yatar. Noktacık tabanlıdır. 24 bit ROB ve CMYK olarak, Alpha kanalı kullanmadan renk üretir. Çok yüksek çözümlemelere (4096 x 4096 noktacık) çıkabilir. Resim detayına bağlı olarak sıkıştırma oranı artar. Sıkıştırma oranı ne kadar yükseltilirse, resmin kapasitesi ve kalitesi düşer. Maksimum 200 kez sıkıştırma yapılabilir. Çoğunlukla eğer görüntü yüksek kalite ayarıyla kaydedilirse çıkarılmış bilginin eksikliği fark edilmez.
