Zmenšit velikost souborů PSB

Formát PSB lze snadno komprimovat, pokud jej uložíte jako PSD, ale formát PSD nepodporuje obraz, který má šířku nebo výšku více než 30000 pixelů. V tomto případě je komprese souboru PSB složitější řešení. Můžete zkusit PSB Compress Software, ale nemůžeme zaručit, že konečný komprimovaný soubor PSB bude čitelný. Tato aplikace používá nezdokumentované funkce formátu PSB. Chcete-li zvýšit šanci na správnou práci, zkuste komprimovat funkce, které neodstraní důležitá data. Snižte velikost PSB za předpokladu „tak, jak je“. Je lepší používat běžné PSD velikost zmenšit aplikaci

Soubory PSB mohou být až 2 GB, takže můžete získat případ, kdy tato aplikace nemůže nahrát soubor PSB, aby se zmenšila jeho velikost. V tomto případě je lepší použít on-premise psd formát řešení jako Aspose.PSD a napište komprimovat kód sami. Příklady kódu horké pro kompresi formátu PSB najdete v tomto článku, stačí přepnout karty ve vestavěné aplikaci PSB File Reduce App
