ASCII to Binary – Convert Text to Binary Codes Instantly

Instantly convert readable text (ASCII) into 8-bit binary format. This tool takes every character from your input and provides its corresponding binary code, separated by spaces for readability. Perfect for computer science students, developers, and curiosities about how data is stored at the lowest level. Works 100% in-browser.

Conversion Direction

How to Use the ASCII ↔ Binary Converter

Operation options:

  • ASCII → Binary: Enter plain text. Each character is encoded as an 8-bit binary byte (e.g. A → 01000001), separated by spaces.
  • Binary → ASCII: Enter space-separated 8-bit binary groups (e.g. 01001000 01101001). Each group is decoded to its ASCII character.

How to use:

  1. Paste or type your input into the Input area.
  2. Select the conversion direction: ASCII → Binary or Binary → ASCII.
  3. The result appears instantly in the Output area. Use Copy to copy your result, or Clear to reset.

Tips:

For Binary → ASCII:

  • Each binary group must be exactly 8 digits long and contain only 0s and 1s.
  • Separate bytes with spaces — e.g. 01001000 01101001 decodes to Hi.

For ASCII → Binary:

  • Every character maps to its standard 8-bit ASCII binary representation.
  • Spaces, punctuation, and special characters are all supported.
