How to use
In Encode mode, type or paste text and select an output format (Hex, Decimal, or Binary). In Decode mode, paste space-separated hex or decimal bytes to convert them back to text.
Why use this tool
Ideal for developers debugging binary protocols, network packets, or encoding issues. The built-in ASCII table is a handy reference for control characters and printable symbols.
FAQ
- What input format does Decode mode accept?
- Space-separated hex values (e.g. 48 65 6C) or space-separated decimal values (e.g. 72 101 108). The tool auto-detects the format.
- Does it support characters outside ASCII (e.g. UTF-8)?
- The tool works with ASCII characters (0–127). For multi-byte Unicode characters, use the Unicode Converter tool instead.
- Is data sent to a server?
- No. All conversion happens locally in your browser. Nothing is transmitted.
