Base64 Encode and Decode Online (UTF-8 Safe)

Type or paste text and press Encode, or paste Base64 and press Decode. Accents, other alphabets and emoji work because the text is handled as UTF-8.
Frequently asked questions
- What is Base64?
- A way to write any data using only letters, numbers, + and /. It is used in emails, data URLs and tokens.
- Is Base64 encryption?
- No. Anyone can decode it, so never use it to hide a password.
- Why does decoding fail?
- The text may contain characters outside the Base64 set, or be missing padding or part of the data. URL-safe Base64 uses - and _ instead of + and /, which this tool accepts.
