Base64 Encoder / Decoder

Encode UTF-8 text as Base64 or decode Base64 back to readable text.

Enter text to convert it.

Base64 encodes bytes as text

Base64 represents binary data with printable characters. It is an encoding format, not encryption.

This tool converts UTF-8 text. Decoding rejects invalid Base64 and byte sequences that are not valid UTF-8.

When to use it

Inspect encoded text from APIs, email payloads, or configuration files.
