Thank you for using Infomaniak for the secure transmission of your large documents to your contacts, thus ensuring a professional and effective solution for your data exchanges.

Preamble

• SwissTransfer is a secure online file transfer platform that allows you to send large files in a simple and effective manner.
• Unlike many other file transfer services, SwissTransfer accepts files up to 50 Go, which is particularly useful for large files that cannot be sent by email or other traditional means.
• Moreover, data security is guaranteed as Infomaniak is particularly committed to confidentiality and ethics are at the heart of its concerns.

Transferring data with SwissTransfer

To send files via SwissTransfer:

• Click here to access the Web app SwissTransfer Infomaniak (online service swisstransfer.com).

Downloading data

Files sent via SwissTransfer can be downloaded by the user…

• … or one by one…
• … or by using the "Download All" button, which will create a .zip archive to download:
  • If it exceeds 10 Go, then you will need to download the contained data one by one.
  • Therefore, if you need to send several dozen large files, it is better to group them yourself beforehand in a zip/rar/etc. archive (read below).

Compress files before sending…

You can transfer multiple files with SwissTransfer by selecting them on your device, even if the data to be sent includes folders.

To facilitate sending, it is not mandatory but easy to compress your files in a format like ZIP for example. These manipulations will create a new compressed folder .zip that can be sent more quickly with SwissTransfer as the total weight will be reduced in principle.

... on macOS and Linux

1. From your computer, select the folder(s) to send.
2. Right-click on the folder(s) to archive.
3. Select the "Compress" option:

This guide explains how to attach files and/or images to emails sent from the Web app Mail Infomaniak (online service mail.infomaniak.com), the complete online solution for reading and managing your emails.

Foreword

• Refer to this other guide regarding limitations on sending emails/attachments.

Attach files from your computer to your message

To add an attachment from your computer:

1. Click here to access the Web app Mail Infomaniak (online service mail.infomaniak.com).
2. Click on New message.
3. Click on the paperclip icon Attach a file.
4. Browse the locations to select the files to attach to the message:
   
   • With the Web app **Mail** Infomaniak (online service mail.infomaniak.com) the size limit for **attachments** is **25 MB**.
     • Beyond that and up to a limit of **3 GB**, a link SwissTransfer is generated and integrated into your message: the data is stored in Switzerland in the Infomaniak Cloud and your recipients will be able to use this link to easily download the attachments during a predefined period.
     • Beyond 3 GB (and up to 50 GB), it is recommended to always use SwissTransfer for your sends.

Attach kDrive files to your message

To add an existing attachment from kDrive:

1. Click here to access the Web app Mail Infomaniak (online service mail.infomaniak.com).
2. Click on New message.
3. Click on the kDrive folder icon to browse locations and select the files to attach to the message.

Include an image in the body of your message

To add an image to the message (in the middle of your message text, for example), there are 2 possibilities:

• Drag/drop the image into the input interface (images over 10 MB will not be displayed but will be attached).
• or Click on the icon representing the frame with the mountains then:
  
   
  1. Click the button to upload an image (which allows you to choose it from your desired location and then insert it into the body of the message)…
  2. … or enter the URL of the image you wish to include; the image must be located somewhere on the Internet (you can use the FTP Manager to send your image to your hosting space if you have one) and must still be there at the time your correspondent views the message.

This guide explains why there might be an error during the download, installation, or use of the mobile app SwissTransfer (app for iOS/Android smartphone or tablet).

Device considered as not secure?

When you use the mobile app SwissTransfer, you might see the message “Your device has been detected as insecure”. This message means that the app cannot guarantee that your device is reliable or meets security requirements.

Indeed, SwissTransfer does not require account creation to function. It relies on integrity mechanisms to ensure that the application is used on a genuine, unmodified device in a secure environment. This system is essential to prevent abuse, fraud, or malicious automation.

On Android, these checks are performed through the "Play Integrity" API provided by Google. If this API returns a result indicating that the device or environment is not reliable, or if it is not available, the device is automatically considered insecure.

Why?

This can happen if the phone is rooted, modified (custom ROM, tools like Magisk), if Google Play services are not installed, are outdated, or if the Play Store is missing or outdated. A device without an active Google account can also cause issues. Network errors or an inability to contact Google's servers can also prevent the verification from taking place.

On iOS, equivalent mechanisms allow detecting jailbroken or modified environments, as well as integrity issues related to the Apple system. Again, if the device does not meet the authenticity criteria, the application may not work fully.

What to do?

This does not prevent you from using **SwissTransfer**: all functionalities related to **receiving and opening transfers** remain accessible. Only the creation of a new transfer is blocked if the device does not pass the integrity check.

If you encounter this issue:

• Check that your phone has not been modified, that all system components are up to date, that you are connected to the Internet and that your device has the required official services (Google Play Services for Android, up-to-date Apple system for iOS).

If necessary, you can always use SwissTransfer from a mobile browser or a computer via the website https://www.swisstransfer.com.
