About This Decimal to Binary Converter

This tool converts decimal numbers to their binary (base-2) representation. You can choose between different bit lengths (8, 16, 32, 64) or let the tool automatically determine the minimum required bits. Negative numbers are converted using two's complement notation.

How to Use This Tool

Step-by-Step Guide:

1. Step 1: Input your decimal numbers using either:
   • Drag and drop a .txt file containing decimal numbers
   • Click to browse and select a file
   • Type or paste decimal numbers directly into the text box
2. Step 2: Select your desired conversion options
3. Step 3: Choose the bit length (or leave as auto-detect)
4. Step 4: Click "Convert to Binary" to process your numbers
5. Step 5: Review your converted binary values in the output box
6. Step 6: Use the results by copying or downloading

Conversion Options Explained:

• Space Separated: Decimal numbers are separated by spaces (e.g., "10 15 255")
• Comma Separated: Decimal numbers are separated by commas (e.g., "10,15,255")
• Line by Line: Converts each line separately, maintaining line breaks
• Bit Length: Controls how many bits are used in the binary representation

Example Conversion:

Input: 10 15 255
Output (8-bit): 00001010 00001111 11111111

Input: -10
Output (8-bit, two's complement): 11110110
