Hexadecimal to Base64 parses a hex string into its underlying bytes and then Base64-encodes them. Input can be space-separated pairs (48 65 6C 6C 6F), colon-separated (48:65:6C), or a continuous hex string (48656C6C6F). All produce the same Base64 output.
How to Use Hexadecimal to Base64
Paste hex bytes into the input.
Click "Encode to Base64".
Toggle URL-safe if needed.
Copy the output.
Common Use Cases
- Encoding hex-formatted cryptographic keys or hashes for use in Base64-only APIs.
- Converting hex packet captures to Base64 for transmission in JSON payloads.
- Verifying encode/decode round trips between hex and Base64 representations.
Example Input and Output
Encoding "Hello" from hex to Base64.

Frequently Asked Questions
Does my hex input need spaces?
No. The tool accepts continuous hex strings like 48656C6C6F as well as spaced, colon, or dash-separated pairs. The only requirement is an even number of hex characters.
What is URL-safe Base64?
URL-safe replaces + with - and / with _, and removes = padding — safe for embedding in URLs and filenames without percent-encoding.
