Send CAD files to clients without the hassle
Getting CAD files to a client usually means wrestling with email attachment limits or clunky FTP setups. WeTransfer cuts through that: upload your files, copy the link, and share it wherever the conversation is already happening. Your client clicks to download, no account needed on their end.
One link, instant access
Engineers and designers working with CAD files need a sharing method that handles large, complex files without altering them. WeTransfer generates a unique download link the moment your upload finishes, ready to paste into an email, a project management thread, or a client chat. DWG, DXF, STEP, IGES, and any other format you work in transfers exactly as-is, with no compression, no conversion, and no change to geometry or metadata. If you are sending proprietary design files or anything sensitive, you can lock the link with a password or restrict access to specific email addresses so only the intended recipients can get through. One link covers as many clients or collaborators as you need, so there is no limit on who can download from the same URL.

FAQs
All your questions answered.
WeTransfer handles any file type you can upload, so DWG, DXF, STEP, STP, IGES, IGS, STL, OBJ, and proprietary formats from tools like SolidWorks, AutoCAD, Revit, or CATIA all transfer without issue. Files arrive at the other end exactly as they left your machine, with no conversion, no re-encoding, and no change to the underlying data. If your CAD package produces a format not listed here, it will still transfer fine — WeTransfer does not restrict by file type.
Go to wetransfer.com, sign in, and add your files using the upload button or by dragging them in. Switch to link mode using the option in the transfer window, then click Transfer. Once the upload completes, WeTransfer gives you a unique URL you can copy and share anywhere, whether that is an email, a Slack message, a client portal, or a WhatsApp thread. The link works for any number of recipients, so one URL covers your entire distribution list.
Yes. WeTransfer supports folder uploads, so you can upload an entire project directory and recipients download it with the original folder hierarchy preserved. This is particularly useful for CAD assemblies where part files, references, and sub-assemblies need to stay organized relative to each other. Just drag the folder into the transfer window the same way you would a single file.
WeTransfer gives you two options for locking down access. You can add a password to the transfer before sending, then share that password with your client separately, so anyone who stumbles on the link cannot download without it. Alternatively, you can enable restricted access and specify the exact email addresses allowed to download, meaning only those recipients can get through even if the link circulates elsewhere. Both options are available on all plans and can be set before you send or updated from your transfers panel afterwards.
Yes. WeTransfer includes download tracking, which you can enable when setting up a transfer. For email-based transfers, you will see a status against each recipient once they download, including the date and time. For link-based transfers, you can enable tracked downloads so that recipients verify their email before accessing the files, and you receive a notification each time someone downloads. This gives you a clear record that the client received and pulled the files, useful when coordinating on project milestones or handoffs.
