Binary to ASCII Converter - Convert Binary Strings to Text

This powerful binary to ASCII converter allows you to convert binary strings to text using various character encodings including ASCII, UTF-8, UTF-16, and many other international character sets. Perfect for programmers, developers, and anyone working with binary data.

How do I convert binary to ASCII text?

To convert binary to ASCII:
1. Enter your binary string (only 0s and 1s)
2. Select the appropriate character encoding
3. Click Convert

The tool will automatically group the binary into 8-bit chunks and convert each chunk to its corresponding character.

What character encodings are supported?

The tool supports many character encodings including:
- ASCII/UTF-8 (default)
- UTF-16 (little and big endian)
- Windows-1252, Windows-1251, etc.
- ISO-8859 series (Latin1, Latin2, etc.)
- Asian encodings: Big5, Shift JIS, EUC-JP, etc.
- Cyrillic: KOI8-R, KOI8-U, CP866
- And many more international character sets

Can I open files directly?

Yes! The tool supports two file opening modes:
- Open File: Opens text files and converts them to binary
- Open Binary File: Opens binary files and converts them to text

This makes it easy to work with existing files without manual copy-paste.

What happens with non-printable characters?

Non-printable characters are handled as follows:
- Printable ASCII (32-126): Displayed normally
- Control characters (9, 10, 13): Tab, newline, carriage return
- Null character (0): Displayed as middle dot (·)
- Other non-printable: Displayed as [hex] format
- Invalid UTF-8 sequences: Displayed as [hex] format

How does the View Selection feature work?

The View Selection feature allows you to:
1. Select text in the output area
2. Click the View Selection button
3. The selected text will be converted back to binary
4. This is useful for reverse conversion or verification

What if my binary string isn't a multiple of 8 bits?

The tool automatically pads your binary string with leading zeros to make it a multiple of 8 bits before conversion. For example, '101' becomes '00000101' before processing.
