Can I change my PayPal to USD?

Could you please elaborate on the process of converting funds from PayPal to US Dollars? I'm particularly interested in understanding if this conversion is directly supported by PayPal, and if so, what steps I need to take to initiate the transaction. Also, are there any associated fees or exchange rates that I should be aware of? Additionally, is there a limit to the amount I can convert, and if so, what is the maximum amount allowed? Lastly, how long does the conversion process typically take, and are there any specific timeframes or windows during which I can complete this transaction?
