Indlela yokuZicimeza JFIF

1 Nciphisa i JFIF images yakho kwibhokisi ephezulu, okanye ukhethe kwisixhobo sakho - akukho nto yokufakela kwaye akukho akhawunti yokuyenza.

2 Khetha ukuba ucofe kangakanani na ngemimiselo ebonisiweyo yohlobo lwefayili: umphakamo womgangatho wemifanekiso, umyinge we-bit rate yesandi, okanye ubungakanani obumiselweyo okanye umphakamo womgangatho wevidiyo.

3 Qala umsebenzi kwaye vumela abasebenzi ukuba baphinde bapakishe ifayile; okuqala wakho akatshintshwanga kwindawo.

4 Uthelekiso lobungakanani obutsha nokuqala, emva koko ulayishe ifayili ecinezelweyo JFIF.
