Pull CAD models, simulation outputs, technical drawings, or specification documents off your desktop and drop them straight onto the WeTransfer homepage — the upload starts immediately. No plugins, no file conversion, and your colleagues or clients can download everything without creating an account.
Uploading made effortless
Engineers regularly need to move large, complex files between teams, clients, and contractors, and a cumbersome upload tool slows that process down. With WeTransfer, you drag your files onto the page and the upload begins right away, so you can be adding recipients or copying a share link while the transfer is already in motion. Every file arrives exactly as you sent it — DWG drawings, FEA results, STEP or IGES models, PDF datasheets, and zipped project archives all transfer without compression or re-encoding, preserving the precision your downstream tools depend on. You can deliver files directly to a recipient's inbox or generate a shareable link to paste into a project tracker, email thread, or procurement document. When you need tighter control — for proprietary designs, pre-tender submissions, or client-facing deliverables — password protection and restricted access let you decide exactly who can open the transfer.
Our features are designed to minimize how much of your data we — or anyone else — can access, so you can keep what's yours, yours.

All your questions answered.
WeTransfer accepts any file type, so you can send CAD drawings (DWG, DXF), 3D models (STEP, IGES, STL), simulation outputs, compressed project archives (ZIP), PDFs, Office documents, and high-resolution images without any conversion. There are no restrictions on format, so whatever your engineering software produces, you can transfer it as-is. Files arrive at the other end in exactly the state they left your machine.
Free accounts support transfers up to 3 GB per transfer, which covers most everyday engineering file exchanges. If you regularly work with large BIM models, full simulation datasets, or multi-gigabyte archives, upgrading to Ultimate removes the per-transfer size cap entirely, so you can send as much as a single project requires without splitting files or worrying about hitting a ceiling.
No. WeTransfer transfers files using lossless handling — nothing is re-encoded, resampled, or reduced. A 3D model or finite element analysis file arrives byte-for-byte as it left your machine, which matters when downstream tools need precise geometry or numerical data. The file size may occasionally appear slightly different in WeTransfer's display due to how storage is calculated, but your actual file content is untouched.
Yes. WeTransfer supports folder uploads, so you can drag an entire project directory — with subfolders for drawings, specs, calculations, and reports — onto the homepage. Recipients download the transfer with the original folder hierarchy intact, which means no manual reorganization on their end and no risk of files being mixed together out of context.
WeTransfer gives you a few ways to control access. You can add a password to any transfer and share it with recipients separately from the download link, so only people who know both can open the files. Alternatively, restricted access lets you lock a transfer to a specific list of email addresses — anyone outside that list is blocked even if they have the link. You can also enable download tracking to see exactly who has accessed the transfer and when, which is useful for audit trails on regulated or commercially sensitive work.
