It provides a private and secure way to hide messages inside PNG or JPEG files using the Least Significant Bit (LSB) technique — right from the browser.\n\n---\n\n## 🚀 Features\n\n- 📤 Upload image (PNG/JPG)\n- 📝 Input secret message\n- 🔐 Encode message using LSB technique\n- 👁️ Preview and download stego image\n- 🧩 Optional: Decode hidden messages from images\n- 💻 100% client-side (No server required)\n\n---\n\n## 📸 How It Works\n\n```mermaid\ngraph TD\n    A[User Uploads Image] --\u003e B[User Inputs Secret Text]\n    B --\u003e C[Text Converted to Binary]\n    C --\u003e D[LSB Bits of Image Pixels Modified]\n    D --\u003e E[New Image Created with Hidden Data]\n    E --\u003e F[User Downloads Stego Image]\n    F --\u003e G[Optional: Upload to Decode]\n    G --\u003e H[Extract LSB Bits and Rebuild Message]\n````\n\n---\n\n## 🧑‍💻 Technologies Used\n\n* HTML5 + CSS3\n* TailwindCSS (for styling)\n* JavaScript (Vanilla)\n* Canvas API (for image processing)\n\n---\n\n## 📂 Project Structure\n\n```\nStegoWeb/\n├── index.html\n├── styles/\n│   └── style.css\n├── scripts/\n│   ├── encode.js\n│   └── decode.js\n├── assets/\n│   └── logo.png\n└── README.md\n```\n\n---\n\n## 🛡️ Security Disclaimer\n\nThis is a basic steganography tool and should **not** be used for encrypting or hiding highly sensitive or confidential information.
