What This Tool Does
Encode text for transport in systems that only support ASCII-safe payload formats.
Use it to inspect or transform input quickly, then carry validated output into code, tests, or API requests.
Common Use Cases
- Build Basic Auth test headers.
- Encode binary-like text for JSON transport.
- Prepare JWT segments for debugging experiments.
Common Pitfalls
- Base64 is not encryption.
- Wrong text encoding can corrupt non-ASCII characters.
FAQ
Is Base64 secure?
No, it is reversible encoding only.
Why does output contain =?
Padding keeps output length aligned to Base64 blocks.
Does this tool send data to a backend?
Most tools process input client-side in your browser unless explicitly noted.
