GlueDo is a cross-platform desktop application built with Python. It allows you to embed one or multiple files inside another file without changing its appearance or usability. Extraction is supported from within the app.

• Embed any file into PNG, JPG, MP3, PDF, or TXT formats
• Extract embedded content from a wrapped file
• Drag-and-drop interface with left/right panels
• File thumbnails and control buttons ("Add", "Clear", "Save")
• Automatically creates a ZIP archive when embedding multiple files
• Final .exe can run independently on any system (no Python needed)

• Hide a .pdf inside an .mp3 to create a stealth audio-document
• Embed a ZIP archive into a .png image
• Distribute multiple files as a single media container
• Conceal sensitive data in harmless-looking files

The app displays two panels (left and right), each accepting drag-n-drop files.

• ➡️ Embeds file(s) from the left panel into the right file
• ⬅️ Embeds file(s) from the right panel into the left file
• If only one panel is filled → triggers extraction into the other panel
• Displays messages like:
  • “FILE IS EMPTY”
  • “NO EMBEDDED DATA FOUND”

To build a standalone Windows executable:

pyinstaller --noconfirm --windowed --onefile main.py
