What is ASCII encoding?
ASCII (American Standard Code for Information Interchange) is a character encoding standard that represents text characters as numeric codes. Each character has a unique code from 0-127.
What's the difference between Decimal, Hex, and Binary formats?
They're different number systems: Decimal (base 10), Hexadecimal (base 16), and Binary (base 2). All represent the same ASCII codes, just in different formats.
Can I encode Unicode characters?
This tool works with ASCII characters (0-127). For Unicode characters, you'll need UTF-8 encoding tools as they require multiple bytes.
What happens if I decode invalid ASCII codes?
Invalid codes will produce unexpected characters or errors. Make sure your input contains valid ASCII codes in the selected format.
Why use ASCII encoding?
ASCII encoding is useful for debugging, character analysis, data transmission protocols, and understanding how computers represent text internally.
