Convert Base64 encoded strings to ASCII codes instantly. Perfect for character analysis and debugging.
Paste your Base64 string below to convert it to ASCII codes
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.
Analyze characters in Base64 data by examining their ASCII codes
Debug text encoding issues by inspecting ASCII values of decoded data
Validate that Base64 data contains expected ASCII character ranges
Learn about ASCII encoding and how characters map to numeric codes
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.
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.
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.
