Binary Code Translator

Binary translator: text to binary and back

A binary code translator converts readable text into 8-bit binary groups (and back) so you can inspect encodings, teach bit basics, or decode classroom puzzles. Each character maps to its UTF-16/UTF-8 code units as the tool implements—handy for demos, not a substitute for a full codec library.

Everything runs in your browser after load. Do not paste passwords, API keys, or private messages into any online encoder.

How to use this converter

1. Paste plain text or a binary string (groups of 0s and 1s).
2. Convert text → binary or binary → text.
3. Copy the result for notes, worksheets, or debugging logs.
4. For hex payloads or Base64 wires, switch to the matching encoder tools.

Before and after examples

Bits, bytes, and readable text

Binary is base-2: only `0` and `1`. Eight bits make a common byte used for ASCII letters. Spaces between byte groups are for humans; strip or keep them consistently when pasting into other tools.

Emoji and non-Latin scripts need more than one byte in UTF-8. If decode looks garbled, check that the binary was produced with the same character encoding assumption as the encoder.

Binary vs hex vs Base64

Hex (base-16) packs the same bits into shorter strings for memory dumps and color codes. Base64 packs bytes into ASCII-safe text for JSON and email. Use binary when teaching bit patterns; use hex or Base64 when integrating with APIs and files.

Classroom and debugging uses

Teachers use text↔binary drills to introduce encoding. Developers sometimes decode legacy logs that dumped bit strings. For network captures and protocol work, prefer hex dump viewers and Wireshark—this translator is optimized for short strings, not pcap files.
