Examples
Tool facts
- Transformation
- Base64 encode / decode
- Encryption
- No
- Typical use

FAQ
Base64 Encoder FAQs
?Is Base64 secure encryption?
No. Base64 only represents data in a text-safe alphabet and provides no confidentiality by itself.
?Why does Base64 make text longer?
Base64 represents binary data using a limited character set, which adds encoding overhead compared with the original bytes.
?Can Base64 contain Unicode text?
Unicode text can be Base64-encoded when it is first represented as bytes with a character encoding such as UTF-8.
