There are a couple of different options actually.
After you’ve placed your order, you’ll have the option of either sharing the files with us through cloud-based storage service such as Dropbox or Google Drive, etc. Or you can send us a direct link to a PDF or an archive file (zip, sitx, rar, etc.) if you have them stored on your website.
OR … you can choose to upload them directly to us using our Uploads Center.
There is a 300mb limit on uploads, so if your archive file is larger than that —
1) make sure your files are all compressed using a loss-less algorithm such as zip or lzw and —
2) if your files are compressed and the archive is still more than 300mb, then you’ll have to send your files in batches of archives. For example, two 150mb archives instead of one 300mb archive.
In order to have access to the Uploads Center you will need an active order or re-order with the change option selected.
