Send CAD files only the right people can open
CAD files carry proprietary geometry, tolerances, and assembly details that belong with specific people. Before you share a transfer link, set a password directly in the upload window and every recipient must enter it before reaching a single file. Password protection is available on every plan and needs nothing beyond a browser.
Keep your files private
Engineering and design files often contain months of development work, and a password gives you a simple, direct way to control who can open what you send. WeTransfer puts the password field inside the upload window, and that password is never included in the notification email WeTransfer sends, so you pass the code to the recipient through whatever channel suits you. Your DWG, DXF, STEP, IGES, SolidWorks, or ZIP packages arrive intact, with no compression, no re-encoding, and no data loss, so every dimension and layer comes through exactly as drawn. If your access requirements shift after a transfer is already sent, you can add, change, or remove the password on any active transfer from your Transfers panel without uploading the files again. For projects where a password alone is not enough, you can also restrict access to a specific list of email addresses, so only the people you name can download even if the link circulates further.

FAQs
All your questions answered.
Open the transfer window, add your CAD files, then look for the password field in the transfer options before clicking Transfer. Type in your chosen password, complete the upload, and every recipient who opens the link will be prompted to enter it before they can reach any file. The password is never sent in the WeTransfer notification email, so you share it with your recipient separately through your own preferred channel.
Yes. Go to Transfers in your account, click the relevant transfer, and you can set, change, or remove the password at any time while the transfer is active. The change takes effect immediately, so if you need to rotate credentials or open access after a review cycle closes, you can do it without re-uploading any files.
No. WeTransfer sends every file in its original state, with no re-encoding, resampling, or quality loss. A DWG, STEP, IGES, or SolidWorks assembly reaches your recipient exactly as you uploaded it, with every dimension, layer, and attribute preserved. If you upload multiple files, they are packaged into a ZIP for download using lossless compression, so nothing inside is altered.
No account is needed to download. The recipient opens the transfer link, enters the password you shared with them, and downloads the files. This keeps things simple for clients, fabricators, or contractors who may not have a WeTransfer account and do not want to create one just to access a set of drawings.
Yes. In addition to setting a password, you can enable restricted access on the same transfer, which limits downloads to a specific list of email addresses. Even if someone has the correct password and the link, they still cannot download unless their email address is on your list. The two controls work together, giving you a second checkpoint that is useful when sharing proprietary designs with a small, named group such as a manufacturer or a client project team.
