Tips & Information

Multiple Prefixes

When decoding, use 0x for hex (0x41), 0b for binary (0b01000001), and 0o for octal (0o101) inputs.

Quick Reference

Common values: A=65, a=97, 0=48, space=32. The character table shows all values for your input.

Extended ASCII

Characters 128-255 are part of extended ASCII and may display differently depending on the encoding used.

Frequently Asked Questions

ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns numerical values to letters, numbers, and symbols. For example, 'A' is 65, 'a' is 97, and '0' is 48.
You can convert text to ASCII in four formats: Decimal (65), Hexadecimal (0x41), Binary (01000001), and Octal (101). Each format is useful for different programming and technical contexts.
Yes! Use the 'ASCII to Text' mode to convert ASCII codes back to readable text. Enter space-separated decimal numbers (like '72 101 108 108 111') and get the original text back.
Yes, the tool supports full Unicode including emojis and international characters. While traditional ASCII is 0-127, this tool shows the full Unicode code point for any character.
The decoder accepts decimal numbers (72 101), hex with 0x prefix (0x48 0x65), binary with 0b prefix (0b01001000), and octal with 0o prefix (0o110 0o145). Values can be space or comma separated.
ASCII defines 128 characters (0-127) covering English letters, digits, and basic symbols. Unicode extends this to over 140,000 characters covering virtually all writing systems, symbols, and emojis worldwide.
