What is Base64 to ASCII Conversion?

Base64 to ASCII conversion is the process of decoding Base64 encoded data and then representing each character as its corresponding ASCII (American Standard Code for Information Interchange) numeric code. ASCII codes are numbers from 0 to 127 that represent standard characters including letters, digits, punctuation, and control characters.

This tool decodes your Base64 string back to text, then converts each character to its ASCII numeric value. The output shows a sequence of numbers representing each character in the decoded text, which is useful for character analysis, debugging, and understanding text encoding.

Frequently Asked Questions

Is Base64 to ASCII conversion secure?

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.

What is the difference between ASCII and Unicode?

ASCII is a 7-bit character encoding supporting 128 characters (0-127), primarily for English text. Unicode is a much larger standard supporting characters from all languages. This tool shows standard ASCII codes for decoded characters.

Should I use spaces or commas as separators?

Both are valid. Spaces are more readable for viewing, while commas are useful for CSV format or importing into spreadsheets and programming languages. Choose based on your needs.

Is this tool free to use?

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