I-GIF ayilahleki kodwa iphoqeleke kumbala we-256-palette ngefremu ngayinye, usebenzisa ukucindezeleka kwe-LZW nokucacile kwe-binary ngombala owodwa. I-WebP inikeza izimo ezilahlekile nezingenalahlekile, ngokukhanya kwe-alpha nokubukeka okutholakalayo kunoma yikuphi.

Ingabe ngizolahlekelwa yikhwalithi eningi uma ngisuka ku GIF ngiye ku WebP?

Ingabe ngingakwazi ukushintsha amafayela amaningi GIF abe WebP ngasikhathi sinye?

Yebo — cindezela amafayela ahlukahlukene GIF endaweni yokulayisha bese siwafaka emgodini ngokufanayo. Abasebenzisi abamahhala bathola i-100 MB ngefayela ngalinye; iPremium ayinaso isikhala ngasinye sefayela futhi isebenza nabasebenza ngokufanayo, ngakho-ke isithombe esingu-200 siqediwe ngezansi kwemizuzu emibini.
