Flow
- Convert text to UTF-8 bytes.
- Encode bytes using Base64 alphabet.
- Return padded Base64 output string.
Example
Worked example: text to Base64
- 1 Input text = pi = π
- 2 UTF-8 bytes are encoded with Base64 alphabet.
- 3 Output = cGkgPSDPgA==
The UTF-8 text is converted into valid Base64 output.
How
- Paste plain text into the input textarea.
- Run encoding or keep live mode enabled.
- Copy Base64 output for downstream use.
Cases
- Encode API payload snippets for testing.
- Prepare auth header fragments in dev workflows.
- Store text fixtures in compact portable format.
Avoid
- Assuming Base64 is encryption instead of reversible encoding.
- Encoding empty input and expecting non-empty output.
- Confusing Base64URL format with standard Base64 output.
