Ingabe amafayela ami GIF afihlakele ngesikhathi sokuguqulwa?

Yebo — amafayela alayishwe phezulu GIF aphathwa emisebenzini ehlukanisiwe futhi asuswa ngaphakathi kwemizuzu. Asikwazi ukufundela, ukugcina, noma ukuhlanganisa idatha ye-pixel. Inqubomgomo yobumfihlo ogcwele kanye nefasitela lokugcinwa kubhalwe ku /privacy/.
