Start typing to convert.
Example
Hello becomes 72 101 108 108 111 in decimal and 48 65 6C 6C 6F in hexadecimal.
Limits and behavior
Only standard 7-bit ASCII values 0–127 are supported, with a 100,000-character input limit. Control codes are preserved when decoding. Extended ASCII code pages and Unicode are different standards and are not guessed.
FAQ
Why is a Turkish letter rejected?
Letters such as İ, ğ, and ş are Unicode characters outside the original 7-bit ASCII range. Rejecting them prevents silent data corruption.
