Windows SmartScreen warning?

Windows and your browser may show a warning because the .exe is not yet code-signed. This is normal for new open-source apps.

To verify the file:

  1. Compare the SHA-256 hash shown above with the one on GitHub
  2. In your browser: click "Keep" → "Show more" → "Keep anyway"
  3. On first run: click "More info" → "Run anyway"

The full source code is available on GitHub — you can build it yourself to verify.

Why a Desktop App?

Extra security, better performance

No Browser Extensions

Runs in its own process — no extensions can observe your encryption keys or file contents.

Hardware-Accelerated

AES-NI encryption at native speed — significantly faster than browser-based WebCrypto for large files.

Drag & Drop

Drop files directly onto the app window. No file picker dialogs, no tab switching.

Parallel Uploads

Multiple chunks upload simultaneously for maximum throughput. Paid tiers get 10 parallel streams.

All Features Included

Password protection, email delivery, custom branding, download limits, link revocation — everything from the web version.

Single Portable Exe

Self-contained, no installer needed. Just download and run. All .NET dependencies are bundled inside.
