Android Studio resimleri uzantıya göre kaydetmek

Android Studio Java kodlamasından oluşan duvar kağıdı uygulamam var. Tüm görseller JPG uzantısı olarak kaydeder ben ise görüntüleri uzantıya göre kaydetmesini istiyorum. Çünkü uygulamaya GIF resim yüklediğim zaman GIF gösteriyor yani oynatıyor. Ancak resmi indirirsem .JPG uzantını olarak indiriliyor ben ise GIF olarak kaydetmesini ve GIF şeklinde paylaşmalarını istiyorum. Ya da resimleri uzantısına göre kaydetmesini. Bunu nasıl yapabilirim?
