Base64 to HEX Converter

Converting Base64 to Hexadecimal Byte Arrays

Developers frequently need to bridge the gap between Base64 transport strings and hexadecimal representations when debugging low-level protocols, inspecting cryptographic hash digests, or reverse-engineering binary formats.

This utility decodes the input Base64 string into raw binary bytes and formats each byte into two hexadecimal characters (0-9, A-F), providing delimiter customization such as space separation, colon separation, or raw hex output.

How to Use

1. Paste your Base64 string into the input text area.
2. Select your desired byte separator (spaces, colons, or continuous hex string).
3. The hexadecimal representation appears instantly in the output panel.
4. Copy the hex string or byte length statistics for use in your code.

Key Features & Capabilities

• Instant conversion of Base64 to uppercase or lowercase hexadecimal.
• Custom delimiter support including space, colon, comma, or continuous hex.
• Calculates total byte length and hexadecimal string length in real time.
• 100% private in-browser conversion without server requests.

Common Developer Workflows

• Analyzing binary communication protocols and network packet captures.
• Inspecting cryptographic tokens, HMAC digests, and raw public keys.
• Converting encoded firmware binaries into hex dump views for reverse engineering.
• Cross-verifying hash checksums between different encoding formats.
