WebP Amathuluzi

Tshintsha WebP kuya futhi kusuka kumafomethi ahlukahlukene

Mayelana WebP

I-WebP inikeza ukucindezela okungcono kakhulu okungenakulahlekelwa nokungalahleki kwezithombe eziku-inthanethi, okwakhiwe yi-Google.

Ukusetshenziswa Okuvamile

Ukuthuthukisa izithombe zewebhusayithi ukuze zilayishwe ngokushesha
Ukunciphisa ukusetshenziswa komkhawulokudonsa kokuqukethwe kwewebhu

Ukushintsha kufomethi ngaphandle kwe-alpha kuyilapho kudlula khona okungalungile: izifunda ezibonakalayo zigcwele umbala oqinile, ngokuvamile omnyama noma omnyama, futhi akukho indlela yokubuyela emuva encane yokufihla isiqephu futhi.
