How it works
- Text is converted to UTF-8 bytes in the browser.
- Encoding creates a Base64 representation of those bytes.
- Decoding validates the Base64 input and converts UTF-8 bytes back to text.
Limitations
- Binary files are not supported in the initial scaffold.
- Invalid Base64 or non-UTF-8 output is reported as an error.
FAQ
Is Unicode text supported?
Yes. The tool uses TextEncoder and TextDecoder so non-ASCII text round trips correctly.
Can I decode arbitrary binary data?
This scaffold is text-focused. Binary file handling can be added later with a file-safe UI.
