Ok, let's say I have an offline wallet for storing my bitcoin, now I have got a good amount of bitcoin, but i don't want to take out everything from the wallet, I only want to take out a small amount, is that possible?

What sort of offline wallet? This is important to know, for example if you are using a paper wallet then the procedure to safely spend will be very different than the procedure for a hardware wallet, etc.– chytrikCommented Nov 6, 2019 at 0:46

Yes, bitcoin is divisible to the 0.00000001 bitcoin, we call this small amount the "Satoshi" for example so even if you got less than 1 bitcoin you have a pretty wide margin on what amount you want to transfer it could be 200.0099 or 0.0005123 be careful of the fees though
For the transfer part I suggest you to use electrum
You will find more useful information about the transfer from cold to online wallet there: Can I spend/transfer bitcoins directly from cold storage?
Yes, it is possible. Basically any bitcoin wallet application should allow you to choose exactly how much to send to another address.

1Note: sending a transaction that doesn't spend the entire offline wallet's balance will most likely create a change address. It is VERY important to understand how a change address works, for example if OP has a paper wallet and spends only part of the balance, the remaining balance will no longer be stored at the paper wallet's address. This can (and has) lead to a loss of funds for users in the past.– chytrikCommented Nov 6, 2019 at 0:50

care to explain? let's say I have got 10 bitcoins on a paper wallet, now i only want to take out 1 bitcoin, you mean the remaining 9 will be changed to another address?– oliberCommented Nov 6, 2019 at 1:07

@oliber yes (but that also depends on how many UTXOs represent those 10 BTC). Each UTXO must be spent in it's entirety, so the remainder will be sent to a new address you control (a 'change address'). Generally, whatever software you use to send craft and send the transaction will automatically create a change address for you (but it will not be the paper wallet address! It will be a new one). See: bitcoin.stackexchange.com/questions/736/…– chytrikCommented Nov 6, 2019 at 1:21

yes that's a good point about paper wallets. When @oliber said 'offline wallet', I assumed it was a hardware wallet, in which case the wallet would take care of the change address.– DariusCommented Nov 6, 2019 at 13:55

@chytrik, realistically if you want to send from a paper wallet, you'll use an app which imports your private key from the paper wallet, then creates, signs, and broadcasts your transaction for you. The app will most likely make a 'change' address for your 9 bitcoins. If you want to store those 9 bitcoins in another paper wallet, you should get the app to send it to that new paper wallet. You could re-use the old paper wallet although it's a bit less secure (realistically probably secure enough though) and makes your transactions easier to track.– DariusCommented Nov 6, 2019 at 13:56
