We use WeTransfer for receiving your files. You can send up to 10 GB (some older browsers will only support transfers of 2 GB). To send multiple files, you must create a single, compressed archive. This will also reduce the size of the files and make the transfer quicker. To compress files on a Mac, Control+mouse click on your folder, and select “Compress …” when the contextural menu appears.
Please let us know if you’re having technical issues with our upload page. You can call us at 612.339.7725 or email firstname.lastname@example.org.
