As a freelancer on Upwork, you may be curious if a client has viewed your proposal. The good news is that there is a way to tell if a client has viewed your proposal. Under Sent Proposals, freelancers can see the viewed icon on the right side which provides the timestamps of when clients viewed their proposals. Freelancers can also look at the bell icon on the top navigation bar for notifications about any viewed proposals. This information can help freelancers identify when their proposals are being viewed by clients, allowing them to adjust their strategy if needed. However, it's important to keep in mind that just because a proposal has been viewed doesn't necessarily mean that it will be accepted. It's also worth noting that clients are never sent a PDF file or any other file containing your profile page, if that's what you're asking.
