How to use Base64
Base64 is an encoding that represents binary data as text. It is not encryption, so never use it to protect secrets.
Encode text as Base64
Choose Encode, enter your text, and run the tool. UTF-8 content such as Korean and emoji is fully supported.
Decode Base64 as text
Choose Decode and enter a Base64 string. Invalid characters, padding, and non-UTF-8 bytes produce a clear error.
