Sending files securely: how to protect your files in 2026
Passports, contracts, medical documents — not every file should be easy to intercept. This is how to send sensitive files securely.
Why does sending securely matter?
Ordinary email attachments are not encrypted. Someone who intercepts your internet traffic — on a public Wi-Fi network, or through a data breach at your provider — can read the content.
For everyday files that hardly matters. But for sensitive documents such as passports, tax returns, medical records or business contracts, you want to be sure that only the recipient can open the file.
What makes a file transfer secure?
Three things count:
1. An encrypted connection (HTTPS)
Your file is sent encrypted from your device to the server. Nobody can intercept it during the transfer.
2. A unique download link
Only someone with the exact link can download the file. Share the link through a secure channel (e.g. WhatsApp or Signal).
3. Automatic deletion
After a set period the file is deleted from the server automatically. That way your passport is not stored anywhere unnecessarily.

Is email safe for sensitive files?
Ordinary email is not suitable for sensitive documents:
- Attachments are stored on the mail servers of both the sender and the recipient
- Email providers such as Gmail scan attachments
- Files stay in the mailbox for years, even if you forget about them
- A mistake or a forward makes files visible to others unintentionally
Better: send a download link by email that expires after 24 hours. Then the file does not sit permanently in someone's mailbox.
Comparing the security of each method

| Email attachment | Partly | No | Depends |
| Google Drive | Yes, but Google can read along | No | Limited (US) |

Practical tips
- Choose a short expiry (1 day) for highly sensitive documents
- Send the download link through a different channel than the file itself
- Do not use public Wi-Fi for uploading sensitive files
- After receipt, check the file arrived correctly and then remove the link
