Can I convert a Base64 string that contains non-ASCII characters?

The tool supports UTF-8 decoding, so strings with extended character sets will convert, though the displayed result depends on your terminal or editor's encoding support.

Is there a limit on the length of Base64 input I can decode?

The material does not specify a character limit, but very long strings may require patience as the tool processes the data in the browser.

Does the tool only decode, or can I also encode ASCII text to Base64?

The interface provides both encoding and decoding capabilities, allowing users to convert ASCII to Base64 as well as decode Base64 to ASCII.

What happens if I upload a file to decode?

The converter accepts file uploads and will process the Base64 data contained within the file, outputting the decoded ASCII text in the result area.
