What is ASCII Converter?

The ASCII Converter is a free online tool that converts text to ASCII codes and ASCII codes back to readable text instantly in your browser. ASCII (American Standard Code for Information Interchange) is the foundational character encoding standard that assigns numeric values to letters, digits, punctuation marks, and control characters. Every character you type has an ASCII code â€” the letter A is 65, lowercase a is 97, the space character is 32. Understanding ASCII is essential for programming, data encoding, debugging character encoding issues, and working with low-level text processing. This tool supports both decimal ASCII codes and hexadecimal representations, making it useful for developers, students, and anyone working with character encoding.

Why Use DevBench ASCII Converter?

DevBench ASCII Converter runs entirely in your browser — your data never leaves your device. No sign-up, no limits, no watermarks, completely free forever.

Frequently Asked Questions

What is ASCII?

ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns numbers 0-127 to characters. It includes uppercase letters (A=65 to Z=90), lowercase letters (a=97 to z=122), digits (0=48 to 9=57), punctuation marks, and control characters like newline (10) and tab (9).

What is the difference between ASCII and Unicode?

ASCII only covers 128 characters (0-127) and is limited to English characters and basic symbols. Unicode is a superset that covers over 140,000 characters from all world languages, emoji, and special symbols. The first 128 Unicode code points are identical to ASCII, making ASCII a subset of Unicode.

What are extended ASCII codes (128-255)?

Extended ASCII uses values 128-255 for additional characters like accented letters, box-drawing characters, and symbols. However, there is no single standard for extended ASCII â€” different code pages (like ISO-8859-1 or Windows-1252) assign different characters to these values.

Can I convert non-English characters to ASCII?

Standard ASCII only covers English characters and basic symbols. Non-English characters like accented letters (Ã©, Ã¼, Ã±) or characters from other scripts (Chinese, Arabic, etc.) are not part of standard ASCII. They require Unicode encoding (UTF-8, UTF-16) instead.

What are ASCII control characters?

ASCII codes 0-31 and 127 are control characters that do not represent printable text. Common ones include: 0 (null), 9 (tab), 10 (line feed/newline), 13 (carriage return), 27 (escape), and 127 (delete). These are used to control text formatting and terminal behavior.
