Range Validation
Warns if any code is outside the valid ASCII range (0–127).

Saved me hours. The live conversion and character counter are exactly what I needed for debugging API payloads.

Super clean interface. The stats panel showing input vs output size ratio is incredibly useful for understanding encoding overhead.

❓ FAQ
What is ASCII?+
ASCII (American Standard Code for Information Interchange) is a 7-bit character encoding that assigns numbers 0–127 to characters. It includes uppercase (65–90) and lowercase (97–122) letters, digits (48–57), punctuation, and 33 control characters.
What are ASCII control characters (0–31)?+
Codes 0–31 are non-printable control characters with special functions: 0 (NUL), 7 (BEL/bell), 8 (BS/backspace), 9 (TAB), 10 (LF/newline), 13 (CR/carriage return), 27 (ESC). They originated from teletype machine signals.
What is the ASCII code for space?+
Space is ASCII code 32 (decimal), 0x20 (hex), or 00100000 (binary). It's the first printable ASCII character. Codes 33–126 are visible printable characters; code 127 is DEL (delete), a control character.
What is the difference between ASCII and Unicode?+
ASCII covers only 128 characters (7-bit). Unicode supports over 1 million code points and includes every writing system. UTF-8 is backward compatible with ASCII — the first 128 UTF-8 code points are identical to ASCII.
Can this tool handle extended ASCII (128–255)?+
Standard ASCII is 0–127. Extended ASCII (128–255) varies by encoding (ISO-8859-1, Windows-1252). This tool validates for 0–127 strict ASCII but will still convert codes 128–255 using String.fromCharCode().
