Isicindezeli sezithombe: nciphisa izithombe ngaphandle kokuzilayisha
Isithombe esisodwa sefoni singasinda amamegabhayithi amahlanu, ayishumi, noma ngisho neshumi nanhlanu. Lokho kuyalunga uma kusegalari yakho, kodwa ngesikhathi uzama ukusinamathisela ku-imeyili, ukusifaka kuwebhusayithi, noma ukusithumela ngengxoxo enciphisa amafayela amakhulu, ubukhulu buba yinkinga. Isicindezeli sezithombe sixazulula lokhu ngokubhala kabusha ifayela ukuze lithwale isithombe esifanayo ngamabhayithi ambalwa kakhulu. Isicindezeli Sezithombe se-speedor.net senza wonke lo msebenzi ngaphakathi kuthebhu yakho yesiphequluli, kudivayisi lakho siqu. Akukho okulayishwayo, akukho okugcinwayo kuseva, futhi ifayela elicindezelwe lilungele ukugcinwa masinyane nje lapho izibalo ziqedile.
Kungani usayizi wefayela lesithombe ubaluleke ngempela
Izicindezelo ezintathu ziphusha abantu abaningi baye ekucindezeleni. Eyokuqala isivinini. Ku-web, izithombe ngokuvamile yizona zinto ezinzima kunazo zonke kufanele ikhasi lizilayishe, futhi amakhasi asindayo enza izivakashi zilinde, zenyuke zisuke, futhi zingaphindi zibuye. Ukunciphisa igalari isuka kumamegabhayithi ayishumi nambili iye kwambili kungaba umehluko phakathi kwekhasi elizizwa lisheshayo nelinye eliyimayo kuxhumo lwefoni. Isicindezelo sesibili yimikhawulo eqinile. Abahlinzeki be-imeyili banikeza umkhawulo ezithasiselweni, amafomu okusekela enqaba noma yini engaphezu kwamamegabhayithi ambalwa, kanye nemakethe zenqaba ukubhaliswa lapho izithombe zikhulu kakhulu. Ukucindezela kuvumela isithombe sangempela ukuthi sishone ngaphansi kwaleyo micophelelo ngaphandle kokuthi ususe ingxenye yefreyimu. Isicindezelo sesithathu wukugcinwa nesixhaphozi. Amafayela amancane asho ukuthi izithombe eziningi zingena kudivayisi, ukusekelwa kuqeda ngokushesha, futhi abantu abakuxhumo olulinganiselwe noma oluhamba kancane abaqedi idatha yabo balanda isithombe sakho.
Ukulahlekelwa okuthile kanye nokungalahlekelwa lutho, ngendlela elula
Kunezindlela ezimbili ezibanzi zokwenza isithombe sibe ncane. Ukucindezela okungalahlekelwa lutho (lossless) kuqoqa idatha ngobuhlakani obukhulu ngaphandle kokulahla lutho, ngakho isithombe esikhishiwe sifana ncamashi nomthombo. Kuqinisile kodwa kulinganisiwe: ngokuvamile wonga ingxenye encane yosayizi. Ukucindezela okulahlekelwa okuthile (lossy) kuya ngale kancane ngokususa unomphela imininingwane iso lomuntu okungayiboni kalula, njengokushintsha okuncane kombala esibhakabhakeni noma umumo omncane ethunzini. Ngoba kususa idatha, kungenza isithombe sibe ncane kakhulu, ngokuvamile ngamaphesenti angu-60 kuya ku-80, kusabukeka kahle. Inkinga wukuthi imininingwane esusiwe iyanyamalala unomphela, ngakho akukuhle ukuphinda ucindezele ifayela elifanayo njalo njalo. Indlela efanele ukugcina umthombo wakho ongathintekile ndawonye ephephile bese ucindezela ikhophi lapho udinga inguqulo elula.
Ukuqinisekisa phakathi kwekhwalithi nosayizi
Isicindezeli ngasinye siveza uhlobo oluthile lwedayali yekhwalithi, futhi ukuthola indawo elungele ngempela kuyona yonke inhloso yomdlalo. Yenyusa ikhwalithi kuze kufike engqongweni futhi ifayela alincipha kakhulu. Yehlise kakhulu kakhulu futhi uqala ukubona izimpawu zokucindezela ngokweqile: izikwele ezinjengamabhulokhi eziseceleni komphetho, ukuguquka kombala okudidayo, kanye nomkhondo omncane womsindo eceleni kwemigqa eqinile. Kwizithombe eziningi, isilinganiselwa sekhwalithi esiphakathi kuya kwesiphezulu sisusa ubuningi bobunzima kubuhle bushiya isithombe singahlukene nomthombo osayizini wokuhlola ovamile. Indlela eqotho yokwahlulela "kwanele" ukubheka umphumela esikrinini lapho uzosetshenziswa khona ngempela. Isithombe esizoba avatar encane singabekezelela ukucindezela okuqinile; isithombe esikhulu segunya elivele emonithini yedeskithophu lidinga isandla esithobekile.
Yiziphi izifomethi ezicindezela kahle
Ukukhethwa kwefomethi kwenza ingxenye enkulu yomsebenzi ngaphambi kokuba uthinte nendlela yedayali yekhwalithi. I-JPG iwumqhudelwano owakade wagcina ubukhulu wezithombe; injini yayo elahlekelwa okuthile ilungiselelwe amathoni abushelelezi nokuguquka kwezinto zezwe langempela. I-WEBP ikhetho lesimanje futhi ngokuvamile idlula i-JPG ngasikhathi sinye kwikhwalithi ebonakalayo, ikhiqiza amafayela ambalwa kakhulu ngokubonakalayo, futhi isekelwa yiwo wonke amabhrawuza asebenzayo njengamanje. Ezithombeni, lokho kokubili yikhetho lakho elingcono. I-PNG idlala indima ehlukile: ayilahlekelwa lutho futhi ikhanyisela kumidwebo enombala oyisicaba nemiphetho ecacile, njengokhiya, izithombe zesikrini, imidwebo, kanye nanoma yini enokungabonakali. Ukuphusha isithombe kuye ku-PNG kuthambekele ekwenzeni ifayela elikhulu, kanti ukugcina isithombe sesikrini sombhalo njenge-JPG kukhiqiza ukudida okubi eceleni kwezinhlamvu. Fanisa ifomethi nokuqukethwe konke okunye kube lula kakhudlwana. Uma futhi udinga ukushintsha izilinganiso zephikseli, hlanganisa leli thuluzi nesi-sishintshi sosayizi wezithombe sethu, uphequlule konke okunye kuma-mathuluzi ezithombe ethu okusika nokuguqula.
Ubumfihlo bokucindezela ngokwendawo
Iziveza eziningi ze-inthanethi zithumela ifayela lakho kuseva ekude, ziwenze khona umsebenzi, bese zibuyisela umphumela. Lokho kusho ukuthi isithombe sakho esiyimfihlo, isithombe sesikrini, noma idokhumenti kwakha isikhashana kumshini womunye umuntu. Isicindezeli se-speedor.net asikwenzi lokhu. Yonke inqubo isebenza kusiphequluli sakho isebenzisa izinsiza zekhompiyutha yakho siqu, ngakho isithombe sihlala kudivayisi lakho kusukela ekuqaleni kuze kube sekugcineni. Lokho kuphephe ngempela kunoma yini ebucayi, kusasebenza ngisho noma uxhumo lwakho luphelile phakathi nomsebenzi, futhi kuyashesha nakho ngoba akukho hambo ephindiwe okumele ulinde. Ungakwazi ukucindezela ifolda yezithombe zomndeni noma incwadi eyimfihlo ngokuthula okufanayo kwengqondo. Uma usuqedile, hlola amanye amathuluzi aqala ngobumfihlo kuqoqo lethu la-mathuluzi ezithombe.
Imibuzo evame ukubuzwa
Izithombe zami ziyalayishwa kuseva?
Cha. Isithombe ngasinye sicindezelwa ngokwendawo kusiphequluli sakho usebenzisa idivayisi lakho siqu. Ifayela alikaze liphume kukhompiyutha yakho, futhi akukho okugcinwayo noma okuthunyelwa noma kuphi.
Ukucindezela kuzokwenza isithombe sami sibukeke sibi kakhudlwana?
Ngezilinganiso ezinengqondo, umehluko awubonakali eso. Kuphela uma ushayela ikhwalithi phansi kakhulu lapho izimpawu ezinjengamabhulokhi nokuguquka okudidayo kuqala ukubonakala, ngakho hlola umphumela kusayizi ohlela ukuwusebenzisa.
Yini umehluko phakathi kokucindezela okulahlekelwa okuthile nokungalahlekelwa lutho?
Ukuqoqwa okungalahlekelwa lutho kugcina iphikseli ngalinye lifana nomthombo kodwa konga isikhala esincane. Ukucindezela okulahlekelwa okuthile kususa imininingwane amehlo akho angayiboni kalula futhi kunciphise amafayela kakhulu, nakuba idatha esusiwe ingeke ibuyiselwe.
Iyiphi ifomethi okufanele ngiyikhethe ukuze ngithole ifayela elincane kakhulu?
Ezithombeni, i-WEBP ngokuvamile ikhiqiza ifayela elincane kakhulu kwikhwalithi enikeziwe, kanti i-JPG isondele kuyo futhi ivumelana kabanzi. Kokhiya, izithombe zesikrini, nemidwebo enombala oyisicaba, i-PNG yikhetho elingcono.
Ngingasicindezela isithombe esifanayo ngaphezu kwesikhathi esisodwa?
Ungakwenza, kodwa ukudlula ngakunye okulahlekelwa okuthile kususa imininingwane engeziwe unomphela. Kungcono ukugcina umthombo wakho ungathintekile bese ucindezela ikhophi entsha noma nini lapho udinga inguqulo elula.
Kungani ngicindezela kunokuthi ngishintshe nje usayizi?
Ukushintsha usayizi kushintsha izilinganiso zephikseli, kanti ukucindezela kunciphisa usayizi wefayela ngezilinganiso ezifanayo. Zixazulula izinkinga ezahlukene futhi zisebenzisana kahle uma udinga kokubili ukuncipha nokuba lula.
