Cov duab tuaj ntau hom, thiab txhua tus muaj kev siv. Qee cov ntawv txuas ntxiv uas koj yuav khiav mus yog JPEG, TIFF, PSD, BMP, PICT, thiab PNG.
Ntawm no yog qee cov lus qhia dav dav rau kev siv txhua hom ntaub ntawv:
- Yog cov duab yog rau lub vev xaib lossis mobile, siv JPEG, PNG, lossis GIF.
- Yog tias cov duab yuav tshwm sim hauv cov khoom luam tawm, siv TIFF.
- Yog tias koj xav khaws cov ntawv uas tseem tuaj yeem kho tau, xaiv koj cov software cov ntaub ntawv ntuj xws li PSD rau Photoshop.
Thaum siv JPEG
Joint Photographic Experts Group (JPEG lossis JPG) yog qhov zoo tshaj plaws rau cov duab thaum koj xav tau khaws cov ntaub ntawv me me thiab tsis txhob hnov qab muab qee qhov zoo rau qhov txo qhov loj.
Thaum cov ntaub ntawv JPEG pib, lub compressor saib cov duab, txheeb xyuas cov xim sib txawv, thiab siv lawv hloov. Cov xim ntawm lub compressor tsis qhia tias yog "poob." Tus nqi ntawm cov ntaub ntawv xim hauv daim duab txo, uas kuj txo cov ntaub ntawv loj.

Peb hom JPEG yog Baseline, Baseline Optimized, thiab Progressive.
- Baseline (Standard) - Txhua lub web browsers paub txog hom JPEG no.
- Baseline Optimized - Qhov kev xaiv hom JPEG no muab cov xim zoo dua thiab zoo dua me ntsis compression. Tag nrho cov browsers niaj hnub txhawb nws, tab sis yav dhau los tsis tau. Nws yog koj qhov kev xaiv zoo tshaj plaws rau cov ntaub ntawv JPEG hnub no.
- Progressive - Tsim cov ntaub ntawv JPEG uas tso tawm thaum nws rub tawm, pib blocky, thiab tau txais kev pom meej dua thaum nws rub tawm. Nws tsis ua kom cov duab rub tawm sai dua, tab sis nws tuaj yeem muab qhov kev xav ntawm kev nrawm txij li cov duab blocky loads tam sim ntawd ntawm kev sib txuas qeeb. Nrog rau feem ntau ntawm cov neeg siv internet ntawm kev sib txuas ceev niaj hnub no, Progressive JPEG tsis tshua siv.
kab hauv qab
TIFF (Tagged Image File Format) yog haum rau txhua hom bitmap (pixel-raws li) dluab destined rau luam vim hais tias hom ntawv no siv qhov kev lag luam CMYK xim qauv. TIFF tsim cov ntaub ntawv loj, ua tsaug rau ib qho kev daws teeb meem ntawm 300 ppi uas tsis muaj qhov tsis zoo. TIFF tseem khaws cov khaubncaws sab nraud povtseg, alpha pob tshab, thiab lwm yam tshwj xeeb thaum khaws cia los ntawm Photoshop. Hom ntaub ntawv ntxiv uas khaws cia nrog TIFF cov ntaub ntawv sib txawv hauv Photoshop sib txawv, yog li sab laj nrog Photoshop cov kev pab kom paub meej ntxiv.
Thaum siv PSD
PSD yog Photoshop's natural format. Siv PSD thaum koj xav tau khaws cia cov khaubncaws sab nraud povtseg, pob tshab, kho cov khaubncaws sab nraud povtseg, qhov ncauj qhov ntswg, clipping paths, txheej style, blending hom, vector text, thiab shapes.
Tsuas yog Photoshop tuaj yeem qhib thiab kho cov ntaub ntawv PSD, tab sis qee tus neeg kho duab yuav qhib lawv.
kab hauv qab
Siv BMP rau txhua hom bitmap (pixel-raws li) cov duab. BMPs yog cov ntaub ntawv loj, tab sis lawv tsis muaj qhov tsis zoo. BMP tsis muaj txiaj ntsig tiag tiag dhau TIFF, tshwj tsis yog tias koj tuaj yeem siv nws rau Windows wallpaper. BMP yog ib hom duab uas tshuav dhau los ntawm cov hnub qub ntawm lub computer graphics thiab tsis tau txais kev siv ntau ntxiv lawm.
Thaum siv PICT
PICT yog ib qho qub, Mac nkaus xwb bitmap hom siv rau Quickdraw rendering. Zoo ib yam li BMP rau Windows, tsis muaj coob tus neeg siv PICT ntxiv lawm.
Thaum siv PNG
Siv-p.webp
Txhawm rau khaws cov pob tshab, khaws cov ntaub ntawv-p.webp
Thaum siv GIF
Siv-g.webp
