Lossy compression, siv los ntawm hom zoo li JPEG, tshem tawm cov duab cov ntaub ntawv mus tas li kom txo cov ntaub ntawv loj. Qhov tseem ceeb yog nrhiav qhov chaw qab zib qhov twg compression yog maximized thaum tswj qhov pom kev zoo. Rau feem ntau cov duab hauv web, JPEG qhov chaw zoo ntawm 75-85% muab qhov sib npaug zoo, txawm tias qhov no tuaj yeem sib txawv raws li cov duab cov ntsiab lus.\n\nLossless compression, siv los ntawm PNG thiab qee cov duab WebP, txo cov ntaub ntawv loj yam tsis muaj kev poob zoo.

Qhov no ua rau tsis muaj compression zoo tshaj plaws rau cov duab uas zoo yog qhov tseem ceeb, xws li cov duab khoom rau e-lag luam lossis cov duab uas yuav raug kho ntxiv.\n\nCov txheej txheem compression Advanced muaj xws li kev nce qib JPEG loading, uas qhia cov duab hauv kev ua kom zoo dua, thiab chroma subsampling, uas txo cov ntaub ntawv xim uas tib neeg lub qhov muag tsis tshua nkag siab.

Qhov tseem ceeb yog nkag siab pixel ceev thiab cov cuab yeej muaj peev xwm. Ib daim duab 1200px dav yuav zoo meej rau kev saib duab, tab sis nws yog overkill rau 375px mobile screen, nkim bandwidth thiab qeeb load sij hawm. Tsim ntau qhov ntau thiab tsawg ntawm cov duab kom ntseeg tau tias txhua lub cuab yeej tau txais cov duab tsim nyog.\n\nCov duab teb siv HTML’s srcset tus cwj pwm thiab cov duab kos los pab cov duab sib txawv raws li qhov loj me thiab kev daws teeb meem.
