Send CAD files without the size headaches
CAD files are dense by nature. Assemblies, drawings, and project packages can grow well beyond what any email client will accept. WeTransfer handles them straight from your browser, no plugins or desktop software required, and nothing gets compressed or altered along the way. Free accounts support files up to 3 GB, and Ultimate lifts the size limit entirely.
No file is too big
Getting a CAD file to a colleague, client, or fabrication partner should not involve splitting archives or hunting for an FTP workaround. WeTransfer lets you upload directly from the browser and share a download link that works on any device, with no account needed on the receiving end. Your files arrive exactly as you exported them, whether that is a single DWG, a full Fusion 360 assembly, or a folder of referenced files with the original directory structure preserved. You can lock the transfer with a password or restrict access to specific email addresses if the design is confidential. For larger projects or ongoing client work, upgrading to Ultimate means no transfer size cap and transfers that stay live for as long as the job requires.

FAQs
All your questions answered.
Free accounts support transfers up to 3 GB, which covers most individual CAD files and smaller assemblies. If you are sending full project packages with multiple components, referenced files, or high-detail mesh exports, upgrading to Ultimate removes the size limit entirely.
No. WeTransfer sends your files exactly as they are, with no compression, no conversion, and no alterations of any kind. What you upload is precisely what your recipient downloads, which matters when file integrity is critical for manufacturing, engineering review, or client handoff.
Yes. WeTransfer supports folder uploads, and recipients download them with the original folder structure preserved. That means linked files, external references, and project subfolders all arrive in the right place, ready to open without any manual reorganization.
WeTransfer supports any file type, so you can send DWG, DXF, STL, STEP, IGES, OBJ, FBX, and any other format your CAD or design software exports. There are no format restrictions or compatibility requirements on the platform's end.
You have a couple of options. You can add a password to the transfer so only recipients who have it can access the download. You can also restrict access to specific email addresses, meaning only those addresses can open the link. Both options are available on all plans, including the free tier.
