BIN ⇄ Intel HEX Converter

A lightweight, responsive, and pure front-end tool designed to convert files between Binary (BIN) and Intel HEX formats directly in your browser.

✨ Features

• Plug & Play: No installation required. Runs entirely in any modern web browser.
• Drag & Drop: Supports dragging files directly into the interface for quick loading.
• Privacy Focused: 100% client-side processing. Your files are never uploaded to any server, ensuring firmware security.

  • Supports custom Base Address (Offset).
  • Auto-Trimming: Intelligently identifies and removes redundant 0xFF or 0x00 padding at the end of BIN files to produce compact HEX files.
• Robust HEX → BIN:
  • Full support for Extended Linear Address Records (Type 04).
  • Strict Checksum Validation: Errors are caught with precise line numbers and details if a HEX file is corrupted.
• Cross-Platform: Works on Chrome, Edge, Firefox, Safari, and even mobile browsers.

🚀 How to Use

1. Select File: Click the "📂 Choose File" button or simply drag and drop a .bin or .hex file into the container.
2. Set Offset (Optional): If converting BIN to HEX, you can modify the starting hex address in the BIN2HEX OFFSET field.
3. Convert:
   • Click BIN → HEX to generate an Intel Standard Hexadecimal file.
   • Click HEX → BIN to generate a raw binary image.
4. Download: Once processed, the browser will automatically prompt you to save the output file.

⚠️ Note on "Directory Memory"

This version uses the standard Browser File API to ensure maximum compatibility across all devices (including mobile and older systems). Due to browser security restrictions, standard APIs cannot "remember" or "lock" your last-used local directory. This is a security feature designed to protect your file system.
