Paste a sequence of character codes and get the text back. The format is detected automatically, or you can set it yourself.
How to use the ASCII to Text Converter
- 1 Paste codes separated by spaces, commas or new lines.
- 2 Leave format on auto-detect, or choose it explicitly.
- 3 Copy the decoded text.

Detected as binary
Input: 0x48 0x69

The 0x prefix is optional
How auto-detection works
If every code is made of eight or more 0s and 1s, it is read as binary. If codes contain the letters a–f or a 0x prefix, they are read as hexadecimal. Otherwise they are read as decimal. Choose a format manually for octal, or when hex codes happen to contain only digits.
