Base64 to Hex
Converts Base64-encoded data to hexadecimal representation.

What Base64 to Hex does
The Base64 to Hex converter on Base64.Guru translates Base64-encoded strings into their hexadecimal equivalents. Users input a Base64 string and receive the corresponding hex output, preserving the original data's integrity during the transformation. The tool handles the dual process of decoding the Base64 input and re-encoding it as hexadecimal, providing a straightforward solution for data manipulation tasks without requiring local software installation.

Best for
Developers, security analysts, and anyone working with binary data who needs a quick, browser-based method to convert Base64 strings into hexadecimal format without installing local encoding utilities.
Limitations
- Output length can be restricted using the Length setting, potentially truncating results
- Hex case (Lowercase/Uppercase) must be manually selected; default behavior not specified
- No indication of file size limits or performance constraints for very long Base64 strings
Base64 to Hex FAQ
- Can I convert hex back to Base64 using this tool?
- Yes, the site provides a reverse converter labeled "Hex to Base64" for the opposite transformation.
- What does the Length setting do when converting Base64 to Hex?
- Specifying a number like "128" limits the output to the first 128 characters of the hex string, while negative numbers like "-128" return the last 128 characters.
- Is there a way to separate hex digits in the output?
- Yes, you can specify a delimiter such as a space or comma to format the hex output with separators between digit groups.
- Does the tool handle uppercase or lowercase Base64 input differently?
- The converter processes standard Base64 character sequences; the Letter Case setting applies to the resulting hexadecimal output, not the input encoding.
