You can use SURFfilesender if your institution has acquired a SURFfilesender licence. When you log in to SURFfilesender, you are presented with a screen where you have to select your institution.

The maximum file size per upload via HTML5 is 500 GB. All modern browsers support HTML5. If you use encryption, then the maximum file size is 2 GB. If your browser doesn't support HTML5, but Adobe Flash, then the maximum file size per upload is always 2 GB. Use another browser or update your browser to be able to send larger files.
Yes, you can. Using SURFfilesender you can send files to anyone you wish, including people and organisations without a licence. As a SURFfilesender user you can send these people a 'voucher' to upload/send files to you.
To use encryption for added security, tick the ‘encryption’ box on the upload page. Come up with a key (password) that you can easily remember and contact the receiver after uploading and sending your files to pass on the key. We advise you do this via a different channel than e-mail, for example by telephone or SMS. As soon as the receiver enters this key they can download the files. The encryption and decryption of files is done by the browser during uploading and downloading. Additional software is not necessary. Warning: to use encryption your upload has to be less than 2 GB.
No, you can download uploaded files via SURFfilesender using any modern, up-to-date browser. There are no additional requirements for downloading files.
If you have a problem logging into SURFfilesender you should contact your institution's helpdesk.
You can resume an interrupted or cancelled upload. To do this you have to re-send the same file with the same name. SURFfilesender recognises the file by its name. Once your upload has started you will see the progress bar start where the previous upload stopped.
When uploading a file, you will see a green tick once the file has been successfully uploaded. This tick will only be visible if you are using an up-do-date browser that supports HTML5.
Yes, you can. However, we advise that you rename the document before resending to be sure that all your changes have been correctly transferred.
No problem. Log in to SURFfilesender and then go to the ‘My Files’ tab. Here you have the option to delete one or more files. The recipient will receive a message that the file is no longer available.
