Text to Base64 — Encode Plain Text as Base64
Convert plain text strings to Base64-encoded output. Useful for embedding text in data URIs, HTTP headers, and configuration files that require ASCII-safe values.
Common Uses for Text-to-Base64
Encoding text to Base64 is required when including credentials in HTTP Basic Authentication headers (username:password encoded as Base64), embedding small text files in data URIs, passing text through systems that only accept ASCII, and storing text in environments that do not support special characters or line breaks.
Frequently Asked Questions
UTF-8 is used by default, which supports all Unicode characters including emoji, CJK scripts, and right-to-left languages. You can switch to ASCII or Latin-1 (ISO 8859-1) in the settings for legacy compatibility.
Yes. Line breaks are preserved in the encoding. The output will contain the Base64 representation of the full text including newline characters (\n or \r\n depending on your OS).
