Send PDFs securely — end-to-end encrypted
Your files are encrypted in your browser. We never see your documents or your password. Secure PDF sharing for the zero-trust era.
Simple. Sophisticated. Secure.
1. Set Access
Choose your file and a secure passphrase. You control the keys from the start.
2. Encrypt Locally
Encryption happens in your browser. The file is sealed before it ever hits the web.
3. Shared Link
Get a unique, high-security URL to share via your preferred messaging platform.
4. Unlock & View
Recipient enters the passphrase. Decryption occurs on their side, instantly.
Fortified by Design.
Guided by Privacy.
End-to-End Encryption
AES-256 GCM encryption ensures that only you and your recipient can read the contents. No exceptions.
Zero-Knowledge Security
Our servers have zero access to your passphrases or data. We store only encrypted blobs of data.
Auto Expiry
Links automatically self-destruct after a set period, from 1 hour to 30 days.
Burn on Read
Enable "Delete After First Access" to ensure the document vanishes the moment it is viewed.
Instant PDF Viewer
A seamless, secure browser viewer. No downloads required if you choose not to.
"We couldn't read your files even if we wanted to."
Local-First Architecture
Unlike traditional cloud storage, the encryption happens on your CPU. We only see encrypted ciphertext. Your passphrase never reaches our database.
Military Grade Standards
We utilize industry-standard Web Crypto APIs and AES-256 encryption. This is the same protocol used for top-secret government communications.
Server never sees file contents
HOW IT WORKS ?
We can't see your files. Ever.
Everything happens locally in your browser; our servers only see encrypted data that even we don't have the keys to unlock.
Your File
Original content selected from your local storage.
Encrypted locally
Scrambled on your CPU before it leaves the browser.
In Transit
Transferred as unreadable, high-entropy binary data blocks.
Stored
Recorded as ciphertext only. We hold no master keys.
Decrypted
Recipient uses the local key to reconstruct the file.
How it works: Web Crypto API
We leverage the native browser Web Crypto API to perform cryptographic operations. This ensures that encryption happens at near-native speeds directly in your user agent, never touching a remote server in plaintext.
Your browser's memory is a sandbox. Encryption happens within this isolated environment.
Hardware-accelerated encryption ensures your machine stays cool while files stay safe.
What the server sees
Only randomized ciphertext blocks. No metadata, no previews, no filenames.
Where the key is
The private key is generated locally on your machine. It is never transmitted. To share a file, the key is passed via a secure URL fragment that browsers never send to servers (anything after the #).
Built for what matters most.
Legal Contracts
Secure signatures and sensitive clauses without leaving a digital trail on central servers.
Financial Records
Send audits, bank statements, and tax documents directly to stakeholders.
Sensitive IP
Protect trade secrets and business strategies with auto-expiring access links.
