How do I convert text to binary?

Paste text with Text → Binary selected. The default UTF-8 setting converts each encoded byte to eight binary digits. For example, A becomes 01000001.

How do I convert binary back to text?

Select Binary → Text, paste eight-bit bytes separated by spaces or a continuous binary string, and choose the original encoding. UTF-8 is the default. Optional 0b prefixes are accepted.

Does it support emoji and non-English text?

Yes. Use UTF-8 or UTF-16. ASCII only represents values 0–127, and Latin-1 only represents code points 0–255; unsupported characters produce an error unless replacement or skipping is selected.

Why does one character produce several binary bytes?

UTF-8 uses one to four bytes per Unicode code point. The letter A uses one byte, while many emoji use four. UTF-16 uses two-byte code units and a surrogate pair for characters outside the Basic Multilingual Plane.

Can I convert binary without spaces?

Yes. Decode accepts continuous digits and reads them in eight-bit chunks. Encoding can use an empty byte separator for compact output. Short final chunks require an explicit padding or dropping option.

Is my text sent to a server?

No. Text encoding, binary parsing and exports run locally in your browser. Saved presets are stored on your device, not uploaded.

About text to binary converter

Convert text to binary code using UTF-8, ASCII, Latin-1 or UTF-16. For example, Hi becomes 01001000 01101001 in UTF-8: H has byte value 72 and i has byte value 105. Each padded byte is displayed as eight binary digits.

UTF-8 supports multilingual text and emoji. A character can occupy more than one byte, so character and byte counts are not always equal. Choose Binary → Text to decode binary using the same character encoding. Invalid characters, incomplete bytes and encoding mismatches produce clear errors instead of silently changing your text.

Advanced settings control byte separators, prefixes, grouping, bit order, text cleanup and byte transformations. Export binary text, a byte table, CSV, JSON or an escaped HTML table, or create a custom row template. Byte-table characters represent individual byte values, not full Unicode characters. Text and conversion stay in your browser; saved presets remain on your device.

How to use Text to Binary Converter

1Paste your text, or choose Binary → Text and paste binary digits.

3Choose byte spacing and padding, or open Advanced for formatting and cleanup.
4Review the output and any validation errors.
5Copy the result or download text, CSV, JSON or HTML.
