How it works
Four steps, start to finish.
Drop your file
Any type, up to 2 GB.
Encrypted locally
Before anything leaves your browser.
Split and stored
Sharded across multiple locations.
Share the link
Only people with the link can access it.
Under the hood
What actually happens to your file.
Key generation
A 256-bit AES key is generated entirely in your browser. Optional ML-KEM post-quantum encapsulation wraps it.
Client-side encryption
Your file is encrypted with AES-256-GCM before any data leaves your device. The key never touches our servers.
Shard distribution
The encrypted blob is split into 4 shards and uploaded to separate storage nodes. No single node holds a complete file.
Zero-knowledge link
The decryption key lives in the URL fragment (#). It never reaches our servers. Only the person you share the link with can decrypt.
The difference
You deserve better than this.
Google Drive
- Scans every file you upload for ad targeting
- Google holds the encryption keys, not you
- Files live on their servers permanently
- Tied to your Google account, everything is tracked
Dropbox
- Employees can access your files if requested
- Encryption keys are controlled by Dropbox, not you
- History of data breaches (68M accounts in 2012)
- Shares data with third parties for analytics
WeTransfer
- Files sit on their servers completely unencrypted
- Anyone with the link can download, zero access control
- Free tier deletes after 7 days but keeps metadata
- No end-to-end encryption on any plan
Email attachments
- 25 MB limit, useless for real files
- Stored in plaintext on every server it touches
- Your ISP, their ISP, and both email providers can read it
- Stays in inboxes forever with no expiration
Snow
Use cases
Built for people who care about what they share.
Whistleblowing & leaks
Submit documents to journalists or oversight bodies. Auto-delete ensures nothing persists.
Edward Snowden had to set up an elaborate encrypted pipeline just to get NSA documents to journalists. With Snow, one link would have done it.
Medical records
Share lab results, prescriptions, or insurance docs without worrying who else can read them.
In 2015, Anthem's breach exposed 78.8 million medical records stored on unencrypted servers. Client-side encryption would have made the stolen data useless.
Contracts & legal
Send NDAs, signed agreements, or sensitive business documents to clients securely.
The Sony Pictures hack in 2014 leaked thousands of contracts, salary sheets, and internal emails. All stored in plaintext on their servers.
Source code
Transfer proprietary code, SSH keys, or config files between teams without exposing them.
In 2021, Twitch's entire source code and payout data leaked from an unprotected internal server. Zero-knowledge storage would have prevented the exposure.
Personal files
Send tax returns, ID scans, or private photos to family. No account required on either end.
The 2014 iCloud breach leaked private photos from hundreds of accounts. The images were stored without end-to-end encryption, making them readable by anyone with server access.
Research & journalism
Share unpublished papers, datasets, or source material that needs to stay confidential.
The Panama Papers source leaked 11.5 million documents to journalists using encrypted channels. Self-destructing links would have added another layer of protection.
Why Snow
Fast, simple, gone when you want it.
Instant links
Upload finishes, link is ready. Share it anywhere.
Works everywhere
No app, no account, no install. Just a browser.
Auto-expires
Files delete themselves. Pick 1 hour to 30 days.
Post-quantum ready
ML-KEM key encapsulation on top of AES-256. Future-proof.
File tools
More than just file sharing.
File Converter
Convert between PNG, JPEG, WebP, AVIF, GIF, and BMP.
Runs entirely in your browser using the Canvas API. Your images never leave your device. No upload, no server processing.
Image Compressor
Reduce file sizes with adjustable quality.
Smart compression that finds the sweet spot between quality and size. PNGs get converted to WebP automatically for better results.
Secure Paste
Self-destructing encrypted text with syntax highlighting.
Share code snippets, passwords, or notes that auto-delete after reading. AES-256 encrypted, with optional access codes and burn-after-read.
Metadata Stripper
Remove EXIF, GPS, and hidden data from photos.
Strip location data, camera info, timestamps, and embedded thumbnails before sharing images. Shows exactly what metadata was found.
Your files. Your keys. Your rules.
No account, no analytics, no compromise. Start encrypting in seconds.
