About File.io
What is File.io?
File.io is a simple, anonymous file sharing service designed for quick, one-time transfers. Upload files up to 4GB (or up to 100GB on Premium) and share a secure link. Files are automatically deleted after the first download (or after a set expiration), making it ideal for sharing sensitive information that shouldn't linger online.
Who is it for?
File.io is perfect for individuals and professionals who need to send large files temporarily without creating an account or worrying about cloud storage clutter. It's especially useful for developers (via REST API), journalists, privacy-conscious users, and anyone who wants a 'Snapchat for files' experience. It is NOT designed for long-term storage, team collaboration, or managing file versions.
Key problem solved
Traditional file sharing services leave your data on servers indefinitely, creating security and privacy risks. File.io solves this by encrypting all files in transit and at rest, then permanently deleting them as soon as they are downloaded or expire. No account required, no personal data collected, and no forgotten files in the cloud.
Real use cases
Send a contract to a client and have it vanish after they view it; share a large design file with a freelancer without clogging your Dropbox; automate temporary file drops via the API for workflow integrations. File.io handles up to 1 TB of downloads per month on the Premium plan, making it scalable for businesses.
Key features
- Auto-delete after download — Files are permanently deleted once the recipient downloads them, ensuring no data lingers.
- End-to-end encryption — All uploads, downloads, and API requests are encrypted via HTTPS/TLS; stored data uses military-grade encryption.
- No account required — Upload and share files instantly without signing up or providing personal info.
- Generous file size limits — Share files up to 4GB (Free), 10GB (Basic), or 100GB (Premium).
- REST API access — Developers can automate file uploads and downloads programmatically.
- Custom domain name — Premium plan allows you to use your own domain for branded file sharing.
- Expiration control — Set a custom expiration time for files so they auto-delete even if never downloaded.
