Input, output, limits
Input is plain text or a Base64 string. Output is the opposite conversion. No binary file upload; limited by browser string size.
Example
Encode: hello → aGVsbG8=. Decode: aGVsbG8= → hello. Invalid Base64 yields an error message.
FAQ
Is text uploaded?
No. Encode and decode both run in the browser.
What is line-by-line mode?
Each line is Base64-converted on its own. That differs from encoding the whole block.
Is it UTF-8?
Yes. Text is treated as UTF-8.
