UploadFiles.io: Ad-Supported Simple Hosting
UploadFiles.io is a simple file hosting service with free 50 GB storage (10 GB per file) and a 5 GB upload limit per file. The free tier is ad-supported, meaning you and anyone who downloads your files will see advertisements. Files do not use end-to-end encryption — UploadFiles.io can access your files. On the free tier, files expire after 30 days. The Pro plan ($5/month) extends expiry to 60-180 days depending on file size and removes ads.
UploadFiles.io is designed for public file distribution where encryption and privacy are not primary concerns. It's straightforward and functional for users who don't mind ads and are willing to accept that the service provider has access to their files.
FileShot: Zero-Knowledge Encrypted File Sharing
FileShot is a zero-knowledge encrypted file sharing platform. Files are encrypted with AES-256-GCM in your browser before upload. The decryption key lives only in the URL fragment and never touches the server. Even FileShot cannot decrypt your files. This architecture guarantees privacy by design — there is no trusted third party.
FileShot offers 50 GB free storage (10 GB per file) with expiration from 1 day to unlimited on the free tier. FileShot includes a desktop app for Windows, macOS, and Linux, and built-in tools: PDF editor, file converter, compressor, metadata scrubber, and virus scanner.
Encryption: Access vs. Privacy
UploadFiles.io uses server-side encryption, which means the service encrypts files at rest using keys they control. This protects files from certain external threats, but it does not prevent UploadFiles.io employees, administrators, or anyone who compromises their infrastructure from accessing your files. If UploadFiles.io receives a legal request for your data, they can comply by decrypting and handing it over.
FileShot's zero-knowledge encryption means the server never receives the decryption key. Files are encrypted before they leave your device. Even if FileShot's servers are compromised, or if FileShot receives a legal request, there is nothing to hand over — the encrypted files are useless without the key, which only you have. This is the difference between server-controlled encryption and true zero-knowledge architecture.
Ads and User Experience
UploadFiles.io's free tier shows ads to uploaders and downloaders. This is how they monetize the service. If you upgrade to Pro ($5/month), ads are removed. FileShot has no ads on any tier.
File Expiration Control
On UploadFiles.io's free tier, files expire after 30 days. Pro users get 60-180 days depending on file size. FileShot gives you full control: choose any expiration from 1 day to unlimited on the free tier. If you want files to remain available longer or indefinitely, the Lite plan ($2/month) removes all expiry limits. You decide how long your files stay live, not the service provider.
Use Cases
UploadFiles.io is suitable for public file distribution where encryption is not a requirement. If you're sharing software downloads, public datasets, or files where privacy is not a concern, and you're okay with ads, UploadFiles.io works for that use case.
FileShot is for anyone who needs confidential file sharing: lawyers sending case files, journalists sharing sources, healthcare professionals transferring patient records, freelancers sending client work, or anyone who wants to ensure their files remain private. If you want zero-knowledge encryption and 10 GB per file free with no ads, FileShot is built for you.
Desktop Integration
UploadFiles.io does not offer a desktop app. You upload and manage files through the web interface. FileShot has native desktop apps for Windows, macOS, and Linux, allowing you to upload files directly from your desktop with drag-and-drop, system tray integration, and local file management. The desktop app brings the zero-knowledge encryption model to a native experience.
Who Should Choose FileShot?
If you need zero-knowledge encryption where even the service provider cannot access your files, FileShot is the right choice. If you want generous file limits (10 GB per file) with no ads on paid plans, FileShot delivers that. If you want full control over file expiration (1 day to unlimited, or unlimited with Lite), FileShot gives you that flexibility. If you want built-in tools for PDF editing, file conversion, compression, and virus scanning, FileShot includes those by default.
