What is Hex to Base64 Conversion?

Hexadecimal to Base64 conversion is the process of converting hexadecimal (base-16) data into Base64 encoded format. Hexadecimal uses digits 0-9 and letters A-F to represent binary data, while Base64 uses a set of 64 characters to encode the same data in a text-friendly format.

This tool takes your hexadecimal string, converts it to binary data, and then encodes it as Base64. It automatically handles common hex formats including strings with or without the “0x” prefix, and validates that your input contains only valid hexadecimal characters.

How to Use This Tool

  1. 1
    Enter or paste your hexadecimal string into the input field (with or without 0x prefix)
  2. 2
    Optionally click “Validate Hex” to check your hex string format
  3. 3
    Click the “Convert to Base64” button
  4. 4
    Copy the Base64 output or download it as a text file

Frequently Asked Questions

Is hex to Base64 conversion secure?

Yes, all conversion happens entirely in your browser. Your hex data never leaves your device and is never sent to any server, ensuring complete privacy and security.

Can I use hex strings with the 0x prefix?

Yes! The tool automatically removes the “0x” prefix if present. You can enter hex strings with or without this prefix, and both uppercase and lowercase hex digits are accepted.

Why does my hex string need even length?

Each byte of data is represented by exactly 2 hexadecimal digits. A hex string with odd length would represent an incomplete byte. If you have an odd-length hex string, add a leading zero.

Is this tool free to use?

Absolutely! This hex to Base64 converter is completely free with no limitations, registration, or hidden costs.
