• Desktop application for offline use
• CLI tool for automation and scripting

Security Features

• AES encryption for metadata storage
• Password-protected encryption/decryption
• Separate storage of metadata and images
• Clean image generation without metadata
• No server-side storage of sensitive data

Usage

Web Interface

1. Upload Image

   • Drag and drop an image or click to browse
   • View original metadata in the results panel

2. Remove Metadata

   • Click "Remove Metadata" to strip all EXIF data
   • Download the cleaned image

3. Encrypt Metadata

   • Enter a secure password
   • Click "Encrypt & Save Metadata"
   • Save the encrypted .metadata file

4. Decrypt Metadata

   • Enter the same password used for encryption
   • Click "Load Encrypted Metadata"
   • Select the .metadata file to view decrypted data

CLI Commands

# Remove metadata
metadata-cli remove input.jpg output.jpg

# Remove and encrypt metadata
metadata-cli encrypt input.jpg output.jpg -p yourpassword

# Decrypt metadata
metadata-cli decrypt input.jpg.metadata -p yourpassword

API Usage

import { encryptMetadata, decryptMetadata } from './utils/crypto';

// Encrypt metadata
const encrypted = encryptMetadata(metadata, password);

// Decrypt metadata
const decrypted = decryptMetadata(encryptedData, password);

Technical Details

Encryption

• Uses AES encryption from CryptoJS
• Metadata is stored in separate .metadata files
• Password-based encryption for secure storage

Image Processing

• Clean image generation using HTML Canvas
• Complete removal of EXIF data
• Maintains original image quality

Security Considerations

• Client-side processing only
• No metadata stored on servers
• Secure password handling
• Encrypted metadata stored separately from images

Development

Prerequisites

• Node.js 18+
• npm or yarn
• Web browser for development
