ASCII Converter

Convert text to ASCII codes in decimal, binary, hex, and octal, or convert codes back to text. Handles printable and non-printable characters.

Frequently Asked Questions

What is the ASCII range?

Codes 0 through 127. 0-31 are control codes, 32 is space, 33-126 are printable characters, and 127 is delete. Beyond 127 belongs to extensions like Latin-1 or UTF-8.

How do I decode a hex byte sequence?

Read pairs of hex digits, convert each pair from base 16 to its decimal byte value (0-255), then look up the character for that value - this tool's 'codes to text' mode expects those decimal byte values (space- or comma-separated), not the raw hex digits themselves.

Is ASCII Big-Endian or Little-Endian?

Single-byte ASCII is byte-order independent. Endianness matters only for multi-byte encodings like UTF-16.
