Browser-Based File Archiving and Encryption

Create ZIP archives, encrypt files with AES-256, and extract uploaded archives — all in the browser. Uses the Compression Streams API and Web Crypto API for native-performance processing. No server-side storage or processing involved.

Key Features

  • Compression: Create ZIP files with standard DEFLATE compression. Already-compressed files (JPG, MP4) can be stored without re-compression.
  • Encryption: AES-256-CBC encryption for sensitive files. Password-protected archives with industry-standard algorithms.
  • Extraction: Preview archive contents and extract specific files without unpacking the entire archive.

Use Cases

  • Email attachments: Bundle multiple files into a single ZIP before sending
  • Document backup: Encrypt sensitive documents before cloud storage
  • Batch sharing: Package project files for team distribution

Privacy

All archiving and encryption happens locally in your browser. Files never upload to any server. Encrypted content remains encrypted until the recipient enters the password on their own device.
