Storing Bitcoin securely is a top priority for every cryptocurrency holder. Among the most trusted cold storage solutions is the paper wallet—a physical document containing your Bitcoin private and public keys, often printed in QR code format. Because it exists offline, a paper wallet is immune to online threats like hacking and malware. However, when you need to access or move your funds, you must import or export Bitcoin to and from this offline medium.
This comprehensive guide walks you through the secure processes of importing Bitcoin from a paper wallet and exporting Bitcoin to a paper wallet, while preserving the integrity of your digital assets. Whether you're securing long-term holdings or accessing funds for transactions, understanding these steps is essential.
What Is a Paper Wallet?
A paper wallet is a form of cold storage where your Bitcoin’s public address (for receiving funds) and private key (for authorizing transactions) are printed on paper. Since it's not connected to the internet, it offers strong protection against cyber threats.
However, its security only holds as long as the private key remains offline. Once you import that key into a software wallet, the offline advantage is lost—making timing and caution critical.

How to Import Bitcoin from a Paper Wallet
Importing Bitcoin means transferring funds from your paper wallet into a software or online wallet by revealing the private key. This process is also known as "sweeping" the wallet.
Step-by-Step Import Process
- Choose a Trusted Software Wallet
Use a reputable Bitcoin wallet that supports private key import (e.g., Electrum, BitPay, or OKX Wallet). Ensure the app is downloaded from an official source. - Access the Import Function
Open your wallet app and navigate to the "Import Private Key" or "Sweep Paper Wallet" option. This is typically found under settings or wallet management. Scan or Enter the Private Key
- Use your device’s camera to scan the QR code of the private key on your paper wallet.
- Alternatively, manually input the private key if scanning isn’t possible.
- Confirm and Wait for Balance Update
After submission, the wallet will scan the blockchain for associated funds. Once confirmed, your Bitcoin balance will appear in the software wallet.
⚠️ Important Security Note: After importing, your paper wallet is no longer secure. The private key has been exposed to an online device. Always transfer any remaining funds to a new cold storage solution immediately.
Best Practices When Importing
- Use an Air-Gapped Device: If possible, use a clean, offline computer to scan the private key and create a transaction without ever connecting to the internet.
- Avoid Public Wi-Fi: Never import keys on unsecured networks.
- Double-Check Addresses: Ensure the scanned private key matches the one printed to prevent theft from tampered wallets.

How to Export Bitcoin to a Paper Wallet
Exporting Bitcoin involves sending funds from an online wallet to a paper wallet for secure long-term storage. Unlike importing, you don’t expose the paper wallet’s private key during this process.
Step-by-Step Export Process
- Generate a New Paper Wallet (Offline)
Use a trusted, offline tool like bitaddress.org (downloaded in advance) to generate a new Bitcoin address and private key. Print it securely—avoid saving digital copies. - Copy the Public Address
Locate the Bitcoin public address (usually labeled “Address” or shown as a QR code). This is where you’ll send funds. Send Bitcoin from Your Online Wallet
- Open your software or exchange wallet.
- Initiate a Send transaction.
- Paste the paper wallet’s public address as the recipient.
- Confirm the transaction amount and network fees.
- Wait for Blockchain Confirmation
After broadcast, wait for at least 3–6 confirmations on the Bitcoin network. You can track progress using a blockchain explorer by entering the address.
Your Bitcoin is now safely stored offline.
Securing Your Paper Wallet After Export
Once your funds are sent:
- Store Physically Securely: Keep the paper wallet in a fireproof safe or safety deposit box.
- Create Backups: Make multiple copies and store them in separate locations to prevent loss from damage.
- Use Tamper-Evident Seals: Protect against unauthorized access by sealing the paper in tamper-proof packaging.
- Avoid Digital Photos: Never photograph or scan your paper wallet—this creates online vulnerabilities.
Frequently Asked Questions (FAQ)
Q: Is it safe to import a paper wallet’s private key?
Yes, but only if done through a secure, trusted wallet app on a virus-free device. Remember: once imported, the paper wallet is no longer safe for future use.
Q: Can I partially transfer funds from a paper wallet?
No. When you import a private key, all funds associated with that address are moved. Bitcoin does not support partial sweeps—only full control of the entire balance.
Q: What happens if I lose my paper wallet?
If you lose your paper wallet and have no backup, access to your Bitcoin is permanently lost. Always create duplicates and store them securely.
Q: Can I reuse a paper wallet after importing?
No. Reusing a paper wallet after import exposes you to theft. The moment the private key touches an online device, it may be compromised.
Q: Are paper wallets still recommended in 2025?
While still secure in theory, hardware wallets are now preferred due to better usability and recovery options (e.g., seed phrases). Paper wallets remain viable for one-time storage but require meticulous handling.
Final Thoughts: Balancing Security and Accessibility
Paper wallets offer a simple, cost-effective way to store Bitcoin offline. By understanding how to import and export Bitcoin securely, you maintain control over your assets while minimizing exposure to digital threats.
However, always treat the act of importing as a one-way transition—once online, move remaining funds to a new cold storage solution immediately.
For those looking to bridge cold storage with modern convenience, platforms like OKX provide secure tools for managing both hot and cold wallets seamlessly.
