Base64 to HEX Converter
Convert between Base64 and hexadecimal (HEX) formats. Essential for developers working with binary data, cryptography, and low-level programming.
What is HEX (Hexadecimal)?
Hexadecimal is a base-16 numbering system that uses 16 distinct symbols (0-9 and A-F) to represent binary data. Each HEX digit represents 4 bits, making it a compact way to represent binary data. HEX is commonly used in programming, cryptography, color codes, and memory addresses.
Common Use Cases
Cryptography: Convert Base64-encoded hashes or encrypted data to HEX for analysis or comparison.
Binary Data Inspection: Debug binary protocols, file formats, or network packets by viewing them in HEX.
Hash Verification: Convert Base64 hashes (SHA-256, MD5) to HEX format for verification against HEX checksums.
Low-Level Programming: Work with memory dumps, byte arrays, or raw binary data in embedded systems.
How It Works
Base64 to HEX: The tool decodes Base64 to binary data, then converts each byte to its two-digit hexadecimal representation (00-FF).
HEX to Base64: The tool converts pairs of HEX digits to bytes, then encodes the resulting binary data as Base64.
Format Notes
HEX strings can be entered with or without spaces/colons (e.g., 48656C6C6F or 48:65:6C:6C:6F). The tool automatically handles both formats. Output HEX is displayed as a continuous string of uppercase characters.
Privacy and Security
All conversions happen locally in your browser. Your Base64 and HEX data are never sent to any server. This ensures complete privacy for sensitive data like cryptographic keys or hashes.
