Text ↔ Binary Converter
Convert plain text into binary (01001000…) and binary back to text — both directions.
About the Text ↔ Binary Converter
Text ↔ Binary Converter turns any string into the 0s and 1s that computers use internally — and reverses the process. It's a quick way to teach the ASCII system, solve CTF challenges or encode short messages for fun.
How to use
- Pick a direction: Text → Binary or Binary → Text.
- Paste your input and press Convert.
- Copy the output (groups of 8 bits per character) or download it as text.
Benefits & key features
- Bidirectional, with sensible spacing between bytes.
- Handles UTF-8 so accented characters and emojis round-trip correctly.
- Zero-dependency and fully offline.
- Great for educators teaching binary and character encoding.
Pro tip
Pair with Base64 Encoder/Decoder when you need a more compact, web-safe encoding — binary is for fun, Base64 is for transport.
