Frequently asked questions
What is the difference between Base64 and Base58?
Both encode bytes as text. Base64 is compact and used everywhere (data URIs, JWTs); Base58 drops easily-confused characters (0, O, I, l) and is used by Bitcoin and IPFS.
How do I convert hex to text?
Set the input format to Hex and paste your hex — the Text row shows the decoded UTF-8 (plus Base64, Base58 and Binary).
Is anything sent to a server?
No. All encoding and decoding happens locally in your browser.
