Frequently asked questions
Does my text get uploaded anywhere?
No. Base64 Encoder runs entirely in your browser — your text is never sent to a server.
Does it work with non-English text and emoji?
Yes. The text is first converted to UTF-8 bytes before Base64 encoding, so Unicode text, emoji and non-Latin scripts are all handled correctly.
How do I decode a Base64 string back to text?
Use the companion Base64 Decoder tool to convert Base64 back into readable text.
