## Description

A DIGITAL PEN ON YOUR PHONE

OpenSig is the simple, private way to sign documents and create independently verifiable proofs for any file. No complex workflows and no file uploads.

Sign PDFs, images, videos, design files, code, ZIPs and more directly with your device. Add optional encrypted notes to record purpose, intent or context. Use OpenSig to approve documents, lock in deliverables, protect your intellectual property, and timestamp important work.

WHY OPENSIG?

• Private by design – your documents never leave your device
• Works with any file type and size
• Create permanent, tamper-proof proofs
• Add optional encrypted annotations such as purpose or message
• No accounts, no uploads, no monthly subscription. Just verify your email and start signing
• Independent verification: anyone with the file can verify your proof

WHAT YOU CAN DO

• Sign and approve documents
• Prove authorship of creative work
• Timestamp drafts, designs and revisions
• Protect ideas, pitches and deliverables
• Verify file integrity before handoff
