Convert Base64 encoded strings to hexadecimal format instantly. Perfect for debugging and data analysis.
Paste your Base64 string below to convert it to hexadecimal
Base64 to hexadecimal (hex) conversion is the process of decoding Base64 encoded data and then representing it as hexadecimal values. Hexadecimal is a base-16 number system that uses digits 0-9 and letters A-F to represent values, making it compact and human-readable for binary data.
This tool decodes your Base64 string and converts each byte to its two-digit hexadecimal representation. You can customize the output with uppercase or lowercase letters and optionally add the “0x” prefix commonly used in programming languages.
Convert Base64 encoded hashes and cryptographic keys to hex format
Inspect Base64 data in hexadecimal for easier byte-level analysis
Convert Base64 encoded binary data to hex for analysis and comparison
Convert Base64 strings to hex format for use in low-level programming
Yes, all conversion happens entirely in your browser. Your Base64 data never leaves your device and is never sent to any server, ensuring complete privacy and security.
Both are functionally identical and represent the same values. Uppercase (A-F) is more common in documentation, while lowercase (a-f) is often preferred in programming. Choose based on your preference or project requirements.
The “0x” prefix is a convention used in many programming languages (C, JavaScript, Python, etc.) to indicate that a number is in hexadecimal format. It's optional and only needed when writing code.
