PrivDrop: Free Encrypted File Sharing That Sees Nothing
File sharing services like WeTransfer and Google Drive store your files in plain text on their servers. That means the company, its employees, and anyone who breaches the service can read your data. PrivDrop is different. Your file is encrypted in your browser before it ever leaves your device, and only the person with the link can decrypt it. We never see your data.
PrivDrop is a free, encrypted file sharing tool built by topriv. No sign-up, no tracking, no metadata stored. Just drop a file, get a secure link, and share it with whoever you want.
How PrivDrop works
PrivDrop uses end-to-end encryption to make sure your files stay private. The entire process happens in three simple steps:
Encrypt
Your file is encrypted with AES-256-GCM directly in your browser. The encryption key is generated locally and never sent to our server.
Share
You get a unique link. The decryption key lives in the URL #fragment - the part of the URL that browsers never send to the server.
Decrypt
The recipient opens the link and their browser decrypts the file locally. The server only ever handles encrypted, unreadable data.
This is what makes PrivDrop a zero-knowledge service. The encryption key exists only in the URL you share - it never touches our infrastructure. Even if our servers were compromised, attackers would get nothing but encrypted noise.
What makes it different
Most file sharing services were built for convenience, not privacy. Here's how PrivDrop compares to traditional platforms:
Traditional file sharing
Files stored in plain text on company servers. The company can read, scan, and analyze your files. Metadata like IP address, upload time, and file name is logged. Requires creating an account with personal information.
PrivDrop
Files encrypted with AES-256-GCM before upload. Zero-knowledge architecture - we physically cannot read your files. No metadata stored, no IP logging. No account needed - just drop and share.
The topriv privacy ecosystem
PrivDrop is part of a larger set of privacy tools built by topriv. Each tool handles a different part of your workflow, and they all follow the same principle: your data stays in your browser.
PrivConvert
Convert files privately. 115+ tools.
.priv Format
Open encryption standard
PrivDrop
Share files securely
Here's how the ecosystem works together: convert your files with PrivConvert (PDF to Word, image compression, and 115+ other tools), encrypt them with the .priv format, and share them securely with PrivDrop. All three tools follow the same principle - your data is processed in your browser, never on our servers.
Use cases
PrivDrop is built for anyone who needs to send files without exposing them to third parties. Here are some common scenarios:
- Sending confidential documents to a lawyer or accountant - contracts, tax returns, and financial records stay encrypted in transit
- Sharing medical records securely - send lab results, prescriptions, or health data without a third party reading them
- Transferring business contracts - share NDAs, proposals, and agreements with end-to-end encryption
- Sending passwords or API keys to teammates - much safer than pasting secrets in Slack or email
- Sharing personal photos without third-party access - your memories, your control
Open source encryption
PrivDrop's encryption is built on the .priv format - an open source encryption standard published on GitHub. You can inspect, audit, and verify exactly how your files are encrypted. No black boxes, no trust-me-bro security.
The .priv format uses AES-256-GCM encryption and is designed to be simple, portable, and language-agnostic. It works in the browser, from the terminal, and in any programming language. Check out the full specification and source code at github.com/toprivHQ/priv-format.
