'''Joint Photographic Experts Group''' ('''JPEG''') atau '''Gugus Pakar Fotografi Gabungan''' ('''GPFG''') merupakan skema kompresi [[file]] [[bitmap]].<ref name="ak">{{cite book
== Sejarah JPEG ==
Dikembangkan awal [[tahun]] [[1980]] oleh ''Joint Photographic Experts Group'' (JPEG).<ref name="es">{{cite book
Standar kompresi file gambar yang dibuat oleh kelompok ''Joint Photographic Experts Group'' ini menghasilkan kompresi yang sangat besar tetapi dengan akibat berupa adanya distorsi pada gambar yang hampir selalu tidak terlihat.<ref name="wk">{{cite book
Meskipun kompresi gambar JPEG sangatlah efisien dan selalu menyimpan gambar dalam kategori warna ''true color'' (24 bit), format ini bersifat ''lossy'', yang berarti bahwa kualitas gambar dikorbankan bila tingkat kompresi yang dipilih semakin tinggi.
