Domande frequenti
What is Base64?
Base64 is an encoding scheme that represents binary data using 64 printable ASCII characters, commonly used to embed data in URLs, emails and JSON.
Does it support Unicode?
Yes. Text is encoded as UTF-8 before being Base64-encoded, so emoji and non-Latin scripts work correctly.
Is my data private?
Yes. Encoding and decoding happen entirely in your browser — nothing is uploaded.
