Seal, open, or send a file. Nothing leaves your browser unless it's locked first.
Zero Zip. Zero compression. Exactly what was sent. No more shrinking photos, splitting files into parts, or fighting attachment limits. Sealing locks a file so only the right key can open it — the diamond cracks if that's ever not the case, whether the key was wrong or the file was changed along the way. A sealed download needs a password you set yourself, shared however you like. A share link needs no password at all — it expires on its own, opens only a limited number of times, and you can switch it off early, any time.
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.
This link has the same power as the code above — anyone who gets it can revoke your link or read its confirmations. Treat it like a password: bookmark it privately, don't paste it into a shared doc or channel.
No password to share — the link itself is the key. Diamond Digit's server only ever holds locked, unreadable data — never the key, never the content, never the recipient's email.
This preview only exists in your browser's memory for this tab. Nothing is written to disk unless you choose to save it. This can't prevent someone from screenshotting or recording their screen — no viewer can.
