Hex to Base 32




Reverse conversion tool: Base 32 to Hex converter

Hexadecimal (base-16) and Base32 are two common number systems used in data encoding, cryptography, and software development. Our free and easy-to-use Hex to Base32 Converter tool allows you to quickly convert any hexadecimal input into a Base32-encoded string. Whether you’re working on TOTP secrets, QR codes, or binary-safe text representations, this tool is optimized for performance and accuracy.

What is Hexadecimal?

Hexadecimal is a base-16 numbering system that uses digits from 0-9 and letters from A-F to represent values. It’s commonly used in computing for representing binary data in a more compact and readable format.

What is Base32?

Base32 is a text-based encoding scheme that represents binary data using 32 printable characters (A-Z and 2-7). It is widely used in email-safe data transmission, QR code encoding, and cryptographic applications like TOTP (Time-based One-Time Passwords).

Why Convert Hex to Base32?

Converting hexadecimal data to Base32 offers several advantages:

  • Human-readable and email-safe format
  • Compact encoding for binary data
  • Compatible with RFC 4648
  • Useful for TOTP secrets, QR code content, and API keys

How Our Hex to Base32 Converter Works?

  1. Input Hex Value: Enter your hexadecimal string (e.g., 4D616E).
  2. Binary Conversion: The hex value is converted to its binary equivalent.
  3. Group into 5-bit Segments: Binary is split into 5-bit chunks.
  4. Map to Base32 Alphabet: Each 5-bit chunk is mapped to a Base32 character.
  5. Apply Padding (if needed): Padding is added to align the result with 40-bit blocks.
  6. Display Result: The final Base32-encoded string is shown.

Example: Convert Hex to Base32

Let’s take a real-world example:

  • Hex input: 4D616E
  • Binary equivalent: 01001101 01100001 01101110
  • Grouped into 5-bit: 01001 10101 10000 10110 1110
  • Mapped Base32 characters: J V Q W 4
  • Final Base32 Output: JVQW4===

This detailed step-by-step output is shown in the tool interface.

Developer Implementations

Here are sample code snippets to help you implement Hex to Base32 conversion in your projects:

Python:

import base64
base32_encoded = base64.b32encode(bytes.fromhex('4D616E')).decode()
print(base32_encoded)

JavaScript:

// Use a base32 library like base32.js or custom logic

Java:

// Use Apache Commons Codec or Google Guava for base32 encoding

Practical Use Cases

  • TOTP (2FA) Secret Keys
  • QR Code Data Representation
  • Encoding Binary Files for Email
  • Data Security in Transmission

Does the tool work offline?

Yes, it’s fully client-side and secure.

Is Base32 more efficient than Hex?

Yes, Base32 encoding is more compact and readable.

Can I decode Base32 back to Hex?

Yes, use our Base 32 to Hex Converter.
