About this Base64 Encoder / Decoder
The Base64 Encoder / Decoder converts text to the Base64 representation commonly used for transporting binary-style data through text-based systems. Base64 is an encoding format, not encryption, so encoded content should not be considered secret.
For related tasks, try URL Encoder / Decoder, HTML Entity Encoder / Decoder or JSON Formatter & Validator.
How to use it
- Paste plain text to encode or Base64 text to decode.
- Choose the required action.
- Copy the converted result from the text box.
Practical example
The plain text “Hello” encodes to “SGVsbG8=”. Decoding that Base64 value returns “Hello”.
Frequently asked questions
Is Base64 encryption?
No. Anyone can decode it, so it provides no confidentiality.
Does the tool support Unicode text?
Yes. The browser logic converts Unicode text before Base64 processing.
Why does Base64 often end with =?
Padding characters are sometimes added so the encoded length aligns with Base64 blocks.
