Base Converter supports conversion between binary (2), octal (8), decimal (10), and hexadecimal (16).

• 📌 Enter a value and select its base, and the tool will automatically convert it to the other three bases.
• ⚡ Supports both uppercase and lowercase letters (A-F in hexadecimal are case-insensitive).
• 🔢 The input value is parsed according to the selected base — for example, the hexadecimal "FF" will be converted to decimal 255.
• 💡 Click the "Example" button to quickly fill in the decimal 255 for testing.
• 📊 Real-time character count is displayed below the input and output boxes.
• ⚠️ If the input value does not conform to the selected base (e.g., the digit 2 appears in binary), an error message will be shown in the output box.
