Converters
Text to ASCII Binary
Translate basic ASCII text to padded binary groups, or recover text from whitespace-separated groups.
About this tool
When to use it
Translate basic ASCII text to padded binary groups, or recover text from whitespace-separated groups.
How to use it
Choose the direction, enter ASCII text or eight-bit groups, and select Convert ASCII. Keep the groups separated with spaces when decoding. Use Unicode for characters that are outside ASCII.

Input
Text to binary: AExpected output
01000001A has ASCII value 65. The tool writes eight digits for readability even though supported values use only seven bits.
Errors and unsupported input
11111111 or an emojiUse byte groups representing 0–127. Non-ASCII characters require a different character encoding; this tool does not treat arbitrary UTF-8 bytes as ASCII.

Questions
Frequently asked questions
Is this a general binary-file decoder?
No. It converts ASCII characters. File Base64 is the appropriate companion for representing arbitrary file bytes as text.
