Plain Text

Base64

Fully supports Unicode text (emoji, accents, non-Latin scripts)

Convert any text — including emoji and non-Latin scripts — to and from Base64 encoding entirely in your browser. Different from our Image to Base64 tool, which is for encoding image files.

常见问题解答

What is Base64 encoding used for?
It represents binary or text data using only safe ASCII characters — commonly used in URLs, data embedded in HTML/CSS, email attachments, and API payloads.
Does this handle emoji and accented characters correctly?
Yes — text is encoded as UTF-8 bytes before Base64 conversion, so any Unicode character round-trips correctly.
Is this different from the Image to Base64 tool?
Yes — that tool encodes image files specifically. This one is for plain text you type or paste directly.
