About Binary Decoder

Binary Decoder is a free online tool that converts binary data back into human-readable text. It supports multiple input formats including raw binary (0s and 1s), hexadecimal, and Base64 encoded data. Whether you are reverse-engineering data packets, debugging encoded transmissions, or studying how computers store information, this tool makes it easy to inspect and convert binary data into text, hex, decimal, octal, or Base64 representations.

The decoder handles multiple character encodings including UTF-8, ASCII, and ISO-8859-1 (Latin-1), so it works correctly with international text and special characters. Advanced options let you specify the binary format (auto-detect, byte-spaced, or nibble-spaced) and bit order (MSB or LSB). All processing happens entirely in your browser using JavaScript — no data is ever sent to a server, keeping your information completely private.

Frequently Asked Questions

What is Binary Decoder? expand_more
Binary Decoder is a free online tool that converts binary data (sequences of 0s and 1s) into readable text. Each group of 8 binary digits represents one byte, which maps to a character in the selected encoding. For example, the binary 01001000 01101001 decodes to the text "Hi".
What input formats are supported? expand_more
The tool accepts three input formats: Binary (raw 0s and 1s, with or without spaces), Hexadecimal (hex digit pairs like "48 65 6C 6C 6F"), and Base64 (standard Base64 encoded strings). You can switch between them using the Input Format dropdown.
What is the difference between MSB and LSB bit order? expand_more
MSB (Most Significant Bit) First means the leftmost bit in each byte has the highest value — this is the standard convention used by virtually all modern systems. LSB (Least Significant Bit) First reverses the bit order within each byte, which is used in some specialized protocols and legacy hardware.
Is my data secure when using this tool? expand_more
Yes, completely. All decoding is performed locally in your web browser using JavaScript. No data is transmitted to any server, stored, or logged. Your binary data and decoded results remain entirely on your device.
