Finish the work. Get it approved.
Hand it over with proof.
Finishing a creative project should feel finished. Get the final version approved, capture sign-off, and release original files in one considered workflow.
Digital sign-off moment
A signature binds directly to the byte-level SHA-256 fingerprint of each approved deliverable.
Legal clarity captured in seconds through typed or handwritten digital ink.
The work is finished.
The certainty isn't.
Creative work is crafted with extreme care, yet delivered through casual download links and ambiguous email chains. Without a definitive handover moment, projects linger indefinitely.
The Ghost Client & Disputed Versions
Files sent over WeTransfer or Dropbox leave zero legal trail. Months later, a client asks to revert or claims they never approved the exported artwork.
Scope Creep Post-Delivery
Without a clear sign-off ceremony, the project finish line remains blurry. Additional edits arrive weeks later, framed as unaccepted work.
Lost Proof & Scattered Threads
Dropbox links expire. Email approvals get buried. Years later, neither the studio nor the client has definitive proof of what was delivered.
One considered ceremony.
From final draft to sealed archive.
Client inspects watermarked work
No accounts required. The client opens a secure link to review watermarked previews and confirm deliverable manifests.
Formal acceptance declaration
The client confirms satisfaction with the exact version presented, acknowledging the scope is complete.
Digital sign-off moment
A signature binds directly to the byte-level SHA-256 fingerprint of each approved deliverable.
Tamper-proof certificate generated
An immutable PDF certificate is issued with verification QR, signer timestamp, and cryptographic file proofs.
Master files unlock for download
With approval sealed, high-resolution master assets unlock instantly for client download.
Proof that endures.
Long after delivery.
When a handover is signed, Keepsake produces a formal PDF certificate with embedded QR verification. Years later, scanning the certificate instantly proves what was approved and accepted.
