How does the free upload & proof service work?

Submit your artwork file and our designers will check and optimise it, then send you a free digital mockup to review. You are never asked for payment until you are 100% happy with the layout proof. Uploads are transferred securely, with a 500 MB limit per submission — for files larger than 500 MB, please provide a cloud storage link (Google Drive / Dropbox / OneDrive) instead.
