Fileshot.io
FreemiumPrivate file sharing with zero-knowledge encryption. Free tier: unlimited storage, 50 GB per file. Share via link with optional passwords. https://fileshot.io
What does this tool do?
FileShot.io is a zero-knowledge encrypted file sharing platform that performs all encryption client-side in the browser before uploading. Files are encrypted using AES-256-GCM with keys derived via PBKDF2-SHA256 and delivered through URL fragments, ensuring the server never has access to decryption keys. The free tier offers unlimited storage with a 10 GB per-file limit, while paid tiers increase file size limits and add features like custom inboxes, API access, and malware scanning. The tool emphasizes privacy as architectural foundation rather than afterthought—it includes optional password protection, burn-after-read functionality, expiry timers, and even a Tor hidden service option for truly anonymous sharing.

Key Features
- AES-256-GCM encryption with PBKDF2-SHA256 key derivation (100,000 iterations) performed entirely in browser
- Decryption keys stored in URL fragment (#) never transmitted to server, invisible to network observers
- Burn-after-read, time-based expiry, and download count limits with cryptographic deletion
- P2P WebRTC mode for direct device-to-device transfer without server storage
- Archive Builder to bundle multiple files into single encrypted link client-side without zipping
- Permanent receive inbox (yourname.fileshot.io) and public portfolio gallery on paid tiers
- REST API and webhooks for programmatic file management and CI/CD integration
- Tor hidden service (filesqi3jl4kzq4sgp42wweaphohrmzmygbw6pjek6x6cjts6qqyh3qd.onion) for anonymous access
- Password protection, randomized download links, and optional malware scanning (Creator tier)
Use Cases
- 1Healthcare professionals securely sharing patient records and medical imaging files with colleagues or specialists
- 2Legal teams exchanging confidential case documents and contracts without exposing them to cloud provider access
- 3Freelancers collecting client files through a permanent inbox link (yourname.fileshot.io) without requiring recipients to create accounts
- 4Developers using the API and webhooks to integrate encrypted file transfers into CI/CD pipelines or design tool workflows
- 5Creative teams sharing large uncompressed design files, video projects, or asset bundles with single-click encrypted sharing
- 6Whistleblowers or journalists anonymously submitting sensitive documents via the Tor hidden service
Pros & Cons
Advantages
- True zero-knowledge architecture—server cannot decrypt files even if compromised, with cryptographic proofs documented in public whitepaper
- No account required for basic sharing; recipients decrypt instantly in browser with just a link, eliminating friction in workflows
- Streaming encryption processes files in 512 KB chunks with flat memory usage, handling arbitrarily large files without RAM bottlenecks
- Generous free tier with unlimited storage and 10 GB per-file, plus optional paid tiers are reasonably priced ($2-12/month) for professional features
- Developer-friendly with REST API, webhooks, and programmatic upload capabilities for automation and integration scenarios
Limitations
- Free tier limited to 10 GB per file—a significant constraint for modern video/design work, requiring paid plan upgrade to $5+/month
- Free tier displays ads and file expiry capped at 90 days, limiting viability for long-term archival or ad-free professional use
- P2P/WebRTC mode requires both parties online simultaneously, reducing utility for asynchronous workflows compared to server-stored alternatives
- No mention of client-side verification tools or detailed audit history—users must trust the whitepaper claims without independent code audit visibility
- Portfolio and inbox features (yourname.fileshot.io) only available on paid Lite+ tiers, fragmenting free and paid user experiences
