Seal any document with patent-filed, IANA-registered verification technology. Built for audit and legal evidence workflows. A forged copy cannot pass verification.
No technical knowledge required. No software to install.
Drop any document. We compute its unique SHA-256 fingerprint — in Blind mode, without ever seeing your content.
7 layers of security seal your document. Any alteration — even a single byte — fails verification instantly.
Anyone can verify authenticity instantly — in an audit, in a dispute, anywhere in the world.
Watch how documents become tamper-evident with 7 layers of security.
Enterprise-grade document protection
In Blind mode, your document is encrypted in your browser before upload — we cannot read it. In standard mode, files are stored only to power your share links and can be deleted anytime.
Every document is sealed with HMAC-SHA256 + Ed25519 dual-signing — cryptographic proof of integrity that anyone can verify.
Animated holographic stamp that rotates in real time — a static copy or screenshot cannot pass verification.
Any modification is detected the moment the document is verified — the stamp freezes and marks it as forged.
.pvf files open in any browser — no special software needed.
Works with PDF, images, text files and more. Any file can be protected.
Built on patent-filed, IANA-registered verification technology and real cryptography
Technology patent filed at the Israel Patent Office. Novel verification architecture.
Official IANA-registered file format. application/vnd.vertifile.pvf — recognized internet standard.
Every document is sealed with HMAC-SHA256 + Ed25519 dual-signing — independent proof anyone can verify.
In Blind mode, documents are encrypted before they reach us — we could not read them if we tried. Not a policy. A design choice you can verify.
Defense in depth for the documents your organization depends on.
Every document gets a unique digital fingerprint. Change one pixel and the fingerprint is completely different.
Two-key verification: one key signs, another verifies. A forged signature cannot pass verification.
Each document proof is sealed with a cryptographic signature — independent, verifiable evidence that the document has not changed since it was sealed.
In Blind mode, your document is encrypted in your browser before upload. We cannot read it — not as a policy, but as mathematics.
Each file carries built-in self-checks that give an instant first-line indication. Authoritative verification runs online against the Vertifile registry.
Animated holographic stamp refreshes every 5 minutes. Screenshots and recordings become useless.
Every access, verification, and download is logged. Full accountability for audits and legal evidence workflows.
With Blind mode, Vertifile cannot read your documents — even if we wanted to, even if compelled. Encryption happens in your browser, and the key never reaches our servers.
Your documents are encrypted with AES-256-GCM directly in the browser, before they ever leave your computer. What reaches our servers is unreadable code.
The encryption key is transmitted only via URL Fragment — a part of the address that is never sent to the server. No one besides you and the recipient can open the document.
Every document is signed with a dual digital signature: Ed25519 for sender identity and HMAC for content integrity. Any change, no matter how small, is detected instantly.
Designed to support GDPR and HIPAA compliance workflows. When the server cannot read your content, there is nothing to leak, nothing to breach, nothing to expose.
A real university diploma protected by Vertifile
Change a single letter and the verification stamp freezes instantly.
Open a real protected document. Then open the same document after a single byte was altered — and watch verification fail in real time.
Built for every sector that runs on trusted documents.
Diplomas, transcripts, certificates
Medical records, prescriptions, lab results
Contracts, court documents, notarizations
IDs, permits, official documents
Employment letters, payslips, references
Invoices, bank statements, audit reports
Everything you need to know about Vertifile
A PVF is a tamper-evident document file format developed by Vertifile. It wraps your original document with cryptographic verification and a live holographic stamp that proves authenticity in real-time.
PVF files open directly in any modern web browser — Chrome, Safari, Firefox, or Edge. No special software or plugins required.
In Blind mode, your documents are encrypted in the browser before they leave your device — we cannot read them even if we wanted to. In standard mode, your file is stored to power its share link and can be deleted anytime. Only the cryptographic fingerprint is used for verification.
Vertifile offers Pro ($29/month, 500 docs, $0.15/doc overage) for individuals and professionals, Business ($79/month, 1,000 docs, $0.10/doc overage) for teams, and custom Enterprise pricing with unlimited documents. Free during early access — no credit card required.
Protection takes seconds. Upload your document and get a tamper-evident PVF file instantly.
PDF, images (JPEG, PNG), and text files. We are continuously expanding supported formats.
