How to send bigger
A TransferThing link
Drop the portfolio, the video or the whole folder here, paste the link in the message. Up to 5 GB, without an account for you or the recipient.
A cloud drive link
Put the file on Google Drive, OneDrive or Dropbox and paste the share link. It uses your storage there; check who can open it.
Make it lighter
Export the PDF with smaller images or shorten the video. It works for a few MB, not for a showreel.
A free account to follow your transfers.
See what was downloaded, and find your links again.
