Features
Everything you need to share securely.
Secure PDF Links
AES-256-GCM encrypted in your browser. The decryption key is the hash fragment — servers never see it.
Live Analytics
See which pages are being read and for how long. Real-time, per-viewer, per-page.
Instant Revocation
One click deletes the encrypted blob from storage permanently. The link dies instantly, everywhere.
Military-Grade Security
Trust no one. Not even us.
- 1
Local Processing
PDF metadata is stripped and the file is encrypted entirely within your browser's memory.
- 2
Blind Storage
We store an encrypted blob. We cannot read the filename, the content, or the metadata.
- 3
Hash-Fragment Keys
The decryption key is appended to the URL as a hash fragment (e.g., #key). Browsers do not send hash fragments to servers.
// Client-side encryption process
const key = await crypto.subtle.generateKey(
{ name: 'AES-GCM', length: 256 },
true,
['encrypt', 'decrypt']
);
const iv = crypto.getRandomValues(new Uint8Array(12));
const encryptedBlob = await crypto.subtle.encrypt(
{ name: 'AES-GCM', iv },
key,
documentBuffer
);
// Key never leaves the browserSEE IT IN ACTION

Frequently Asked Questions
Everything you need to know. Full FAQ at /faq
Can PdfWatch read my documents?
No. Your document is encrypted in your browser before upload using AES-256-GCM. The decryption key lives only in your share link — it is never sent to our servers. We are architecturally incapable of reading your files.
Is there a free plan?
Yes. The free plan is permanent, not a trial. Track up to 3 documents with real-time heatmaps, view counts, and the anonymous burner upload — forever, at no cost.
What happens when I share the link?
Your recipient clicks the link. Their browser decrypts the document locally using the key in the link. They read the document. You see a real-time notification on your dashboard. PdfWatch never sees the decrypted content.
Can I revoke access to a document?
Yes. From your dashboard, click Revoke on any document. The encrypted file is permanently deleted from storage and the link stops working instantly.
Is PdfWatch GDPR compliant?
Yes. Viewer IP addresses are hashed before storage, decryption keys are never stored on our servers, and you can permanently delete all your data from the Settings page at any time.
