Frequently asked questions
- How is Base58 different from Base64?
- Base58 removes easily confused characters (0, O, I, l) and symbols, so it is safer to copy by hand, which is why Bitcoin uses it.
- Is this the same as a Bitcoin address?
- It uses the same alphabet, but real addresses add a checksum (Base58Check). This tool does plain Base58 encoding of text.
- Is my data uploaded?
- No. The conversion runs entirely in your browser.
