DEVELOPER / THE EVERYDAY TOOLKIT
Base64 Encoder / Decoder.
Encode Unicode text to Base64 or decode a Base64 string back to text. Useful for inspecting text payloads, working with API examples and understanding encoded content.
SIMPLE BY DESIGN
How to use Base64 Encoder / Decoder
- Paste plain text to encode, or a Base64 string to decode.
- Select Encode to convert UTF-8 text into standard Base64.
- Select Decode to read standard Base64 as UTF-8 text.
- Review the result and use Copy output.
Text encoding without the extra steps.
Base64 represents binary bytes using a limited set of printable characters. This utility converts text to UTF-8 bytes before encoding, so it supports accents, non-Latin scripts and emoji. The decoder expects standard Base64 containing valid UTF-8 text.
A FEW THINGS TO KNOW
A little more clarity.
Does this support emoji and Unicode?
Yes. Encoding uses UTF-8 bytes, and decoding converts valid UTF-8 bytes back to Unicode text.
Is Base64 encrypted?
No. Anyone can decode a standard Base64 value. Use proper encryption when you need confidentiality.
Why does decoding fail?
The input may be malformed Base64, a URL-safe variant, or binary data that is not valid UTF-8 text.
