Can I convert hexadecimal back to Base64 using this tool?

The site offers a separate Hex to Base64 converter for the reverse conversion process, allowing users to convert hex values back to Base64 encoding.

Does the tool support uppercase or lowercase hex output?

Yes, users can select between Lowercase (a1b2c3) and Uppercase (A1B2C3) letter cases for the hexadecimal output before converting.

Can I format the hex output with delimiters between bytes?

Yes, the tool allows specifying a delimiter such as a space or comma to separate hex digits in the output, or users can leave it default for a continuous string.

Is there a limit on how much Base64 text I can convert at once?

The tool includes a length field where users can specify a character limit (e.g., "128") or use negative numbers to extract the last portion of the hex string, suggesting some output length control is available.
