What is ASCII to Base64 Conversion?

ASCII to Base64 conversion is the process of converting ASCII (American Standard Code for Information Interchange) numeric codes into text characters, then encoding the result as Base64. ASCII codes are numbers from 0 to 127 that represent standard characters including letters, digits, punctuation, and control characters.

This tool takes a sequence of ASCII codes (space or comma-separated), converts them to their corresponding text characters, and then encodes the text as Base64. It validates that all codes are valid ASCII values (0-127) before performing the conversion.

How to Use This Tool

  1. 1
    Enter or paste your ASCII codes into the input field (space or comma-separated)
  2. 2
    Optionally click “Validate ASCII” to check your codes are valid
  3. 3
    Click the “Convert to Base64” button
  4. 4
    Copy the Base64 output or download it as a text file

Frequently Asked Questions

Is ASCII to Base64 conversion secure?

Yes, all conversion happens entirely in your browser. Your ASCII data never leaves your device and is never sent to any server, ensuring complete privacy and security.

Can I use both spaces and commas as separators?

Yes! The tool accepts both space-separated (e.g., “72 101 108”) and comma-separated (e.g., “72,101,108”) ASCII codes. You can even mix them if needed.

What ASCII codes are valid?

Valid ASCII codes range from 0 to 127. This includes control characters (0-31), printable characters (32-126), and the DEL character (127). The tool validates all codes before conversion.

Is this tool free to use?

Absolutely! This ASCII to Base64 converter is completely free with no limitations, registration, or hidden costs.
