Password-protect your engineering PDFs
Engineering documents carry real stakes, whether that's specifications, tender packs, or compliance reports you can't afford to send openly. WeTransfer lets you set a password on any PDF transfer before it goes out, so the files stay locked until the right person enters the right code. No specialist tools, no IT setup — it works on every plan.
Keep your files private
Engineering teams regularly share drawings, method statements, and technical reports where controlling who gets in matters as much as getting the file there. WeTransfer builds the password prompt directly into the transfer, so anyone opening your link is stopped at a gate before a single page of your PDF is visible or downloadable. You set the password while uploading in the transfer window, and it never travels inside the notification email, giving you a separate channel to share it with the intended recipient. PDFs are previewable in-browser once the password clears, so engineers and reviewers can read through documents without downloading immediately. For situations requiring tighter control, you can also restrict access to specific email addresses, adding a second layer on top of the password.

FAQs
All your questions answered.
Yes. WeTransfer supports folder uploads, so you can group multiple PDFs into a single transfer and lock the whole package behind one password. Recipients hit the prompt when they open the link and must enter the correct password before any file in the bundle is accessible. The files arrive exactly as sent, with no quality loss or compression that would affect technical detail.
No. The password stays exactly as you set it for the life of the transfer. You can update or remove it at any time from your Transfers panel without re-uploading any files, so if a project phase ends or personnel changes, you can rotate access without creating a new transfer.
No account is needed to download. Recipients click the transfer link, see the password prompt, enter the code you shared with them separately, and can then preview or download the PDF directly in their browser. The password is never included in the notification email, so you control how and when it reaches the right person.
Yes, and for confidential specifications or commercially sensitive reports it's worth doing both. Password protection stops anyone without the code, while restricted access limits downloads to a specific list of email addresses you define. Even someone who obtains the link and the password cannot download the files unless their email address is on your approved list.
Link transfers have no recipient limit, so you can share a single password-protected link with as many reviewers, contractors, or clients as needed. If you prefer email delivery, free accounts support up to 10 recipients per transfer, while paid plans increase that to 50. Either way, all recipients hit the same password prompt before accessing the files.
