FAQs (Target long-tail keywords)

1. How do I convert an Ethereum private key to an address online? Paste your ETH private key (hex format) into our converter, and it instantly generates the corresponding Ethereum wallet address using the same cryptographic process as ethers.js and web3 libraries.

2. Can I convert a Bitcoin private key to an address using Python? Yes! Our tool shows you the wallet address, and you can replicate the process in Python using libraries like bitcoinlib or ecdsa. We also provide code snippets for Python developers.

3. Is it safe to use a private key to address converter online? Our tool runs entirely in your browser (client-side JavaScript). Your private keys are never sent to any server. However, never use private keys linked to real funds—this tool is for development and educational purposes only.

4. What’s the difference between compressed and uncompressed Bitcoin addresses? Compressed addresses (starting with 1 or bc1) use a shorter public key format, while uncompressed addresses use the full key. Our tool supports both formats for Bitcoin address generation.

5. Can I use this tool for Ethereum testnets like Sepolia or Goerli? Absolutely. Private keys generate the same address across Ethereum mainnet and testnets. Use our tool to quickly get testnet addresses for development.

6. Does this tool support WIF (Wallet Import Format) for Bitcoin? Yes! You can input Bitcoin private keys in WIF, hex, or raw format, and the tool will convert them to the corresponding Bitcoin address.

7. How does ethers.js convert a private key to an address? Ethers.js uses elliptic curve cryptography (secp256k1) to derive a public key from the private key, then applies Keccak-256 hashing and takes the last 20 bytes to create the Ethereum address. Our tool replicates this process.

8. Can I convert a private key to a Bitcoin address without coding? Yes! Our online tool requires no coding knowledge. Just paste your private key, and the address is generated instantly.
