Binary to Text Converter
🔒 ブラウザで動作
Convert text to binary and binary to text. Supports ASCII encoding. Paste text or binary digits and get instant results.
このツールの使い方
- Type or paste text to encode, or paste space-separated binary digits to decode.
- Each character is mapped to its 8-bit ASCII byte, and the direction is detected from what you type.
- Copy the converted output from the result field.
よくある質問
- How is text turned into binary?
- Each character is taken as its ASCII (or Unicode) code point and written as an 8-bit binary number, so “A” (65) becomes 01000001.
- What format should I paste to decode?
- Space-separated 8-bit groups work best, e.g. 01001000 01101001. The tool reads each group as one byte and maps it back to a character.
- Does it handle accented or non-English characters?
- Plain ASCII letters and symbols map cleanly to 8 bits; characters beyond the ASCII range use multiple bytes, which can make the binary longer than one group per visible character.
- Is my text sent to a server to convert?
- No. Encoding and decoding happen in your browser, so whatever you paste stays on your device.
