How to Encode Text to Base64 Online
Type or paste plain text into the box above and it converts to Base64 instantly — no button to click, no upload, and no account needed. This tool only encodes; if you need to decode a Base64 string back to plain text instead, use our dedicated Base64 Decoder.
Example
Typing Hello World encodes instantly to SGVsbG8gV29ybGQ=.
Common Use Cases
- Embedding small binary-safe strings directly in JSON, XML, or config files.
- Preparing values for Basic Authentication headers or API tokens.
- Encoding text or credentials for safe transport through systems that only accept plain text.
FAQs
Is Base64 encoding secure?
No — Base64 is an encoding, not encryption. It's trivially reversible by anyone, so it should never be used to protect sensitive data; it's meant only for representing binary or text data safely as plain text.
Does this support special characters and emoji?
Yes — the input is UTF-8 encoded before conversion, so accented letters, symbols, and emoji encode and decode correctly.
Does this tool also decode Base64?
This page is encode-only, for a simpler, focused experience. Use our separate Base64 Decoder tool if you need to convert a Base64 string back into plain text.
