File Share
Upload and share any file with a one-time download link
About File Share - One-Time Secure File Transfer
Our free File Share tool provides a secure, one-time file transfer service that automatically deletes your file after the first download. Upload any file up to 50MB and instantly receive a shareable link and QR code for quick, private file delivery.
Unlike traditional file sharing services that keep your files indefinitely, our one-time download approach ensures that your files do not persist on servers after delivery. Once the recipient downloads the file, it is immediately and permanently removed from our servers.
With built-in QR code generation, automatic hourly cleanup, and rate limiting for abuse prevention, File Share is the ideal solution for sending sensitive documents, credentials, design assets, and any file that should not remain accessible after transfer.

Tips & Best Practices
- Share links privately: Always send the download link or QR code only to the intended recipient through a trusted communication channel.
- Notify recipients promptly: Remind recipients that the link works only once and expires in one hour, so they should download immediately.
- Use QR for in-person sharing: The QR code is ideal for quickly sharing files with someone nearby using their phone camera.
- Verify the download: Ask recipients to confirm they successfully downloaded the file, since the link will no longer work after first use.
- Encrypt sensitive files: For highly sensitive content, consider encrypting files with a password before uploading for an extra layer of security.
- Stay within limits: You can upload up to 5 files per hour. Plan your sharing sessions accordingly for best experience.
