Seal, open, or send a file. Nothing leaves your browser unless it's locked first.

Zero ZIPs. Zero compression. Exactly what was sent. Send files up to 100MB in their original fidelity. Sealed in your browser, and automatically deleted once a link expires or reaches its view limit.

Creating a .ddg file never changes or removes your original — it stays exactly where it was.

Password (only needed if downloading — not for sending a link) Confirm password

Link expires after

Maximum times it can be opened (1–200)

These settings only apply to a share link — a sealed download has no expiry, since it isn't tracked by any server.

Your download started automatically. The extension is just a label — it isn't required to open the file, and needs no app installed. Share it however you'd normally send something; share the password separately.

Share this link (decryption key built-in) Recipient's email (optional — only opens your own mail app, never sent anywhere) Add a message (optional)

This code lets you revoke the link early or check confirmations. It's saved to a "My sent links" list in this browser, and the same power is embedded in the bookmarkable manage link below — so you're not limited to this one moment to capture it, but treat it as sensitive wherever it ends up. Bookmark this to check confirmations later (works even from a different browser — this browser's storage isn't required)

This link is your master control. Anyone with it can revoke access or read confirmations. Treat it like a password and bookmark it privately.

The link is the key. No passwords required. Our servers only store locked data and can never see your files, keys, or recipient emails.
