Seal & Sign by Swiss Trust Layer
Work from the Word, Excel or PowerPoint document you already have. Swiss Trust Layer creates a point-in-time PDF workflow for a Digital Seal or E‑Signature—without overwriting your Office source.

E‑SignatureIllustrative Word-style workspace · Product flow shown for explanation
Two clear choices
The Office ribbon always shows two distinct actions. Pick the one that describes what you need—no legal or technical guesswork from the person using it.
Digital Seal
Use Digital Seal when the document needs an electronic seal and timestamp. It does not ask a person to sign the document.
E‑Signature
Use E‑Signature when you need a person or several people to sign the same PDF version through the available trust-provider route.
How it works
Every meaningful handoff is visible. The add-in makes a PDF snapshot, shows what will happen next, and waits for the connected service before it presents a result.

Choose a route, then follow the exact document snapshot through the visible decisions before a connected service returns a result.

Keep Office in control
The add-in works from a point-in-time PDF. It makes the document state clear before a trust request begins, so the original Office document stays in your hands.
The returned sealed or signed file is a new PDF. The Office source is not overwritten.
If the document is unsaved, read-only or co-authored, the add-in shows the state and lets you decide how to proceed.
The converted PDF is checked before the request begins, including the current service-size limit.
When others need to sign
Build a draft signer list first. Add people directly by email, or choose from an Outlook address list after giving permission. The final review is the deliberate moment to send a request.
Trusted by context
Trust, identity and signing options are confirmed from the authenticated profile, organisation, jurisdiction and connected provider capability. That keeps the product clear when people work across different regions.
Choose a download-only result when you do not want to keep the output in cloud backup.
Optional cloud backup lets you choose a folder and see the storage available to your profile.
Receipts support later verification, audit and supported recovery—even where a non-backed-up file has expired under the retention policy.
Questions, answered plainly
Each action in the add-in explains the next step in the right place. Here are the principles behind the product journey.
Digital Seal applies the configured electronic seal and timestamp to the reviewed PDF snapshot; no person signs the document. E‑Signature creates a request for one or more people to sign the same PDF version through an available trust-provider route.
No. The add-in creates a separate PDF snapshot for the trust request. The returned sealed or signed result is a separate PDF, and the Office source is not silently overwritten.
The product makes the current document state visible. You can save first or, where available, deliberately continue with the current snapshot. The add-in does not save the Office source for you.
No. Selecting a person from an authorised Outlook address list adds a draft signer. You review the document and signer list before you explicitly dispatch a signing request.
The available route is determined by the authenticated profile, jurisdiction and connected provider capability. The page never assumes availability; the add-in confirms the path for the active request.
You choose download only or, if available, cloud backup. Receipts are retained for audit, verification and supported recovery. File retention and cloud-storage availability are shown in the product for your account and selected option.
Ready when your document is
Open the Office add-in, choose Digital Seal or E‑Signature, and review the snapshot before the next service step begins.
