File Share

How does one-time File Share work?

Upload your file and get a single-use download link plus a QR code. Once the file is downloaded the first time, it is automatically deleted from the server for a clean, secure handoff.

Security and limits

• Maximum file size: 50MB
• Unused links are cleaned up after one hour
• File is deleted right after the first download

Best use cases

• Sending contracts, invoices, or PDFs that should not persist after delivery
• Sharing design assets or code snippets without leaving a permanent trail
• Handing off credentials or configuration files securely (with end-to-end precautions)

FAQ

Is this link really single-use?
Yes. After the first successful download the file is deleted from the server and the link stops working.

How long does a link stay active?
Links expire automatically after 1 hour if not downloaded.

What about file types?
All common file types are allowed up to 50MB.

Tips for secure sharing

• Always share the link or QR only with the intended recipient
• If the file is sensitive, send the link through a trusted channel
• Remind recipients that the link works once; ask them to download immediately

Performance & reliability

Uploads are capped at 50MB to keep transfers fast. Temporary storage is cleaned automatically, and rate limiting helps prevent abuse so genuine users get consistent performance.
