Frequently Asked Questions
How does text to binary conversion work?
Each character is converted to its ASCII or Unicode code point, then that number is expressed in binary (base 2). For example, the letter A has ASCII code 65, which is 01000001 in 8-bit binary.
Can I convert binary back to text?
Yes. If you paste binary (only 0s and 1s) that is a multiple of 8 bits, the tool automatically detects it and decodes it back to the original text.
Does it support Unicode and Chinese characters?
Basic ASCII characters are fully supported. Extended Unicode characters may produce multi-byte encodings depending on the character set used.
