Indlela yokuZicimeza PNG

2 Khetha ukuba kunzima kangakanani ukucofa: umgangatho okanye injongo ye bitrate, kwaye ngokuzenzekelayo ubungakanani obuncinane ukuba ubungakanani bubalulekile kuwe ngaphezulu kweenkcukacha.

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

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

Ewe: ii-akhawunti ezikhululekileyo ziqhubekeka imifanekiso ukuya kwi-5 MB nganye; amacebo angenangxaki abetha loo mgangatho kuqala kunemifanekiso, kuba akukho nto igqityiwe. Ukuba ugqithile kuyo, ukujika kwi-PNG kuqala kuninzi kakhulu ngokwaneleyo - i-BMP ihlala ilishumi ukuya kwezilishumi elinambini iphindaphindo lobungakanani bomfanekiso ofanayo njenge-PNG.

Xa i Cima PNG iphumeze, yintoni ekufuneka yenziwe emva koko?

Umguquli kule ndawo uhambisa imifanekiso ukuya nakwi WebP, PNG, JPG ne AVIF, apho ugqiba khona ukuba ifayile encinci ifanele ilahle iiseva ezidala. Ukwenza oku ngokulandelana okubalulekileyo: khetha ii-pixels kuqala kwaye isiqulathi-zifayili emva koko, kuba isiqulathi-zifayili sigqibo esiphantsi kwaye ii-pixels zibiza kakhulu.

Ingaba iinxuwa ezifanayo ziqhuba into eyahlukileyo?

Iinjini zifana - iilayibrari ezifanayo, abasebenzi abafanayo, iziqhoboshi ezifanayo. Okuhlukileyo kumbono odityanisiweyo, kwaye umbono apha uhlala kwipropathi yefomati le ndawo ibizwa emva: i-.webp efana ne-extension ingagcina i-VP8 frame elahlekile, enye engalahlekiyo, okanye udweliso, ngoko ke indlela yokusebenza efanelekileyo igqibwa ngefayili nganye kunokuba yi-extension nganye.
