How to use this tool
- Paste your codes, separated by spaces (e.g. '01001000 01101001').
- Select whether they're binary, decimal, or hex.
- Read the decoded text instantly.
Paste space-separated binary, decimal, or hexadecimal ASCII codes and this decoder converts them straight back into readable text. It auto-handles whichever number base you pick, so you don't need a separate tool for each format.
Frequently asked questions
- What format do the codes need to be in?
- Space-separated groups: 8-bit binary (01001000), decimal (72), or hex (48) — one group per character.
- Why do I get '(invalid input)'?
- One of the codes couldn't be parsed in the selected base — double-check the format dropdown matches your input, and that groups are separated by spaces.
