I-JPG ayinakubonakaliswa ngokucacileyo, ikhupha ngaphezulu xa igcinwa kwakhona, kwaye ivelisa ukutshixa okubonakalayo kumbala othambileyo nombhalo oqaqambileyo.

Ingaba ndiya kulahlekelwa yintoni ngomgangatho xa ndisuka kwi ICO ukuya kwi JPG?

Kwi umgangatho 80- 85 utshintsho alubonakali kumgama wokubona oqhelekileyo kwaye ifayile ihlala iphantsi nge 60- 80%.

ICO

ICO ipakisha ubungakanani bemifanekiso engumqondiso emininzi kwifayile enye ukuze iiWindows kunye namacebo okucoca ulwelo akwazi ukukhetha ugqibo oluchanekileyo lwemifanekiso engumqondiso yefavicon kunye neendlela ezimfutshane.
