Nchifukwa chiyani malo osinthika amakono amayendetsa Kuchepetsa PDF?
+
WEBP.to imapangidwa m'malo mwa m'badwo watsopano wazosankha zakale: mtundu umodzi womwe umachita kuwonongeka, kuwonongeka, alpha ndi animation, ndipo motsimikizika amalandiridwa pang'ono kuposa JPEG kapena PNG yomwe idachokera. Anthu amafika pano atasankha kuti zosasinthika zakale zimawawononga bandwidth, ndipo lamuloli limayambitsanso: mtundu uti, mtundu uti, zomwe zimachitika ndi kuwala. Kuchepetsa PDF ndi pamodzi ndi kutsitsa ndi akaunti yomweyo, chifukwa chake mafunsowa amafunsidwa m'malo limodzi.
Pamene Kuchepetsa PDF yatha, kodi ndi chiyani chomwe chimayenera kuchitika?
