i-nomacs sisimahla, sivula umthombo ovulekileyo wokujongisisa umfanekiso, oxhasa amaqonga amaninzi. Ungayisebenzisa ukujonga zonke iifomati zemifanekiso eqhelekileyo kuquka iRAW kunye nemifanekiso yepsd.

I-nomacs ibonakalisa iwijethi ebonisa ulwazi olongezelelweyo olufana ne-thumbnails, i-metadata okanye i-histogram. Iyakwazi ukukhangela imifanekiso kwi-zip okanye kwiifayile ze-MS Office ezinokukhutshelwa kulawulo. Imethadatha egcinwe ngomfanekiso inokuboniswa kwaye unokongeza amanqaku kwimifanekiso. Umboniso we-thumbnail wencwadi eneenkcukacha yangoku ibandakanyiwe kunye nephaneli yomhloli wefayile evumela ukutshintsha phakathi kweefolda. Ngaphakathi kulawulo ungasebenzisa isihluzo sefayile, ukuze kube yimifanekiso kuphela eboniswayo amagama efayile anomtya othile okanye athelekise imbonakalo eqhelekileyo. Ukwenza i-cache isebenze kuvumela ukutshintsha ngokukhawuleza phakathi kwemifanekiso.

I-nomacs ibandakanya iindlela zokuguqula umfanekiso wokulungelelanisa ukuqaqamba, umahluko, ukugcwala, i-hue, i-gamma, ukubonakaliswa. Inomsebenzi wombala we-pseudo ovumela ukudala imifanekiso yemibala yobuxoki. Uphawu olulodwa lwe-nomacs lungqamaniso lweziganeko ezininzi. Ngolu phawu unokuthelekisa ngokulula imifanekiso ngokusondeza kunye/okanye ukunweba kwindawo enye kanye okanye ngokuyigquma ngokukhanya okwahlukileyo.
