Hex to Base64 Encoder

A hex to Base64 encoder converts hexadecimal byte values into Base64. Use it when a debugger, hash tool, certificate utility, or binary inspector gives you hex and another system expects Base64.

1. Paste spaced, continuous, or 0x-prefixed hex bytes.
2. The tool removes separators and validates that the number of digits is even.
3. Copy the Base64 output.

Input: 48 65 6C 6C 6F

Output: SGVsbG8=

• Hex must represent whole bytes, so it needs an even number of digits.
• Do not paste decimal byte values into this tool.
• If you need readable text first, decode the hex elsewhere or use a text encoder.

• Reverse the conversion with Base64 to hex.
• Encode plain text with Text to Base64.
• Work with hex text using the Hex converter.
