A desktop application to convert numbers between multiple bases, built with Python and Tkinter.

• ✅ Convert between all bases: Binary · Octal · Decimal · Hex · Base32 · Base64
• 💡 Visual bit LED display — each bit shown as a colored circle
• 🔁 Two's complement with step-by-step explanation
• 📖 "Do it by hand" tab — learn how to convert without a computer
• 📜 Conversion history panel
• 💾 Export history as .txt, .csv, .json or .pdf
• 🌙 Dark / light mode toggle
• 🗂️ Modular codebase — clean separation between logic and UI

• Python 3.8 or higher
• Tkinter (included in the standard Python installation)
• reportlab — only required for PDF export

Every conversion uses decimal as an intermediate step:

Input (any base) → Decimal → Target base

Example: converting 1A (hex) to binary:

1. 1A hex → 26 decimal
2. 26 decimal → 11010 binary

Used to represent negative numbers in digital systems:

+5  →  0000 0101   (original)
       0000 0101
       ---------
C1  →  1111 1010   (invert all bits)
    +          1
       ---------
C2  →  1111 1011   (= -5 with sign)
