Built for Modern Teams That Value Integrity

Webpages can be altered in seconds using DevTools or Photoshop. VerifyShot produces cryptographic, tamper-evident records to document web states with technical clarity and transparency.

Product & Design Teams

Document staging environments, visual bug reports, and client sign-offs with an independent NTP timestamp and cryptographic audit ID.

Researchers & OSINT Analysts

Preserve articles, social media posts, public disclosures, and breaking news before they are edited, retracted, or deleted.

QA, Testing & Internal Documentation

Document visual bugs, staging releases, and deliverable sign-offs with clear time metadata for seamless internal workflows and freelancer-to-client communication.

E-Commerce & Digital Marketers

Track competitor pricing, ad copy variants, promotional campaigns, and marketplace product listings with verifiable timestamps.

Engineered for Verifiable Authenticity

How VerifyShot adds a layer of trust and helps verify whether web captures remain authentic and tamper-evident.

Atomic NTP Time Synchronization

Never rely on local system clocks that can be changed arbitrarily. VerifyShot queries distributed Network Time Protocol (NTP) servers to register the exact atomic time.

DOM Modification Warning

Before capturing, the extension inspects the active DOM tree for local inspector modifications, alerting you if webpage text or elements were altered in browser memory.

Multi-Format SHA-256 Hashes

Each session registers cryptographic hashes for all exported formats (lossless PNG, compressed JPG, and PDF document) under one unique Audit ID.

Zero-Knowledge Image Privacy

Your images never leave your browser. The SHA-256 fingerprint is calculated 100% locally using the Web Crypto API. Only the mathematical hash is recorded.

Unverified Export (Offline Mode)

Need a quick screenshot without cloud registration? Use the secondary "Unverified Export" button to burn in watermarks offline with zero database queries. Always free and unlimited.

Structured PDF Verification Reports

Generate clean, shareable PDF documents with the verified web capture, embedded audit metadata, source URL, and tamper-evident verification banner.

How VerifyShot Works

Effortless capture inside your browser — no heavy software or third-party servers required.

01

Capture Webpage

Click the extension icon to capture either the entire scrolling webpage or visible viewport. VerifyShot automatically fetches atomic NTP time and validates the DOM state.

02

Stamp & Seal

In the integrated editor, crop or review the image. The tamper-evident watermark stamp and cryptographic SHA-256 fingerprint are generated locally.

03

Verify Independently

Anyone can drop the exported file into our public Verifier tool. The browser recalculates the hash and confirms authenticity against the registry in under 0.2s.

Independent Authenticity Verifier

Received a screenshot or PDF sealed with VerifyShot? Test its integrity and provenance in seconds.

Drag & Drop Any PNG, JPG, or PDF

Verification is executed 100% locally in your browser memory. Your files are never uploaded.

Everything You Need to Know

Common questions regarding client-side Zero-Knowledge hashing, legal transparency, and lifetime access.

No. VerifyShot follows strict Zero-Knowledge client-side architecture. Your screenshots are never transmitted to our servers. Only the mathematical SHA-256 hash value (an irreversible 64-character fingerprint) and public time metadata are recorded in the registry.

Standard screenshots rely on your local operating system clock, which can be modified in settings. VerifyShot requests verifiable UTC timestamps from distributed Network Time Protocol (NTP) servers. Furthermore, our capture script inspects the page DOM tree for local inspector alterations before initiating capture.

Anyone can drag and drop your exported PNG, JPG, or PDF file onto our public Authenticity Verifier Tool. The verifier computes the file's SHA-256 hash in client memory and matches it against the registry in milliseconds, confirming whether the file matches the exact SHA-256 record registered at capture time.

Yes! Users who register during our early-adopter rollout receive the early_adopter tier with unlimited quota. When paid subscriptions are introduced later, your early-adopter account remains grandfathered into lifetime unlimited access. You can create your free account here

The secondary download button in the editor burns the timestamp watermark onto the canvas but bypasses all database queries and network calls. It is completely free, unlimited, and ideal for quick internal drafts where permanent verification is not needed.
