See on professionaalne lahendus JPG faili tihendamiseks Python abil. Kasutage Pythonis kõrgetasemelise platvormist sõltumatu tarkvara arendamiseks meie JPG optimeerimise API t. Proovige seda veebis tasuta!
Muutke suured JPG failid väiksemaks ilma kvaliteeti kaotamata. Kustutage mittevajalikud ja kasutamata andmed. Vähendage koodis JPG faili suurust. Python teek pakub arendajatele integreeritud API d JPG sisu optimeerimiseks.
Python teek on iseseisev lahendus ja see ei nõua kolmanda osapoole tarkvara installimist.
