Share engineering files and preview them before any download
WeTransfer adds a browser-based preview to every transfer you send. Engineers, clients, and reviewers can open technical drawings, PDFs, videos, and 3D renders right in the browser, pick the files they actually need, and download only those. Nothing to install, no account required on their end.
Browse files and folders, then download
Engineering handoffs often involve dense, mixed file sets: technical specifications, CAD exports, structural PDFs, site walkthrough footage, and high-resolution reference images all going to different stakeholders at different stages. WeTransfer gives every recipient a preview page they open straight in their browser, so a project engineer can scan a specification document and a client can step through rendered visuals before committing to a single download. Reviewers can leave comments pinned to individual files and mark specific items as favorites, which keeps feedback anchored to the exact drawing or document rather than lost in a separate email chain. Every file arrives exactly as it was uploaded: no re-encoding, no compression, no resolution loss, so CAD exports and 4K site footage reach the other end intact. When a transfer contains sensitive schematics or contract documents, you can lock it behind a password or restrict access to a named list of email addresses.

FAQs
All your questions answered.
Recipients can preview images (including TIFF, HEIC, and RAW formats), PDFs, MP4 and MOV videos, MP3 and WAV audio files, and common Office documents directly in the browser without downloading anything. For engineering workflows this covers rendered images, PDF specifications, site walkthrough videos, and presentation decks. File types not in the preview list, such as native CAD formats, are still transferred at full quality and can be downloaded and opened locally.
Yes. The preview page lets recipients browse all the files in a transfer and download only the ones they need, rather than pulling down the entire package. This is useful when a structural engineer only needs the load calculations PDF from a transfer that also contains site photos, video walkthroughs, and multiple drawing revisions. Recipients can also mark individual files as favorites to flag the ones most relevant to their work.
Yes. Anyone with access to the preview can leave comments tied to individual files, so a reviewer can pin feedback directly to a particular drawing or specification document rather than describing it in a separate message. Comments are visible to everyone with transfer access, and the sender receives an email notification each time a new comment is posted. The sender can enable or disable comments before sending, and the preference carries forward to future transfers.
No. WeTransfer does not compress, re-encode, or alter your files in any way during transfer. What you upload is exactly what the recipient downloads, whether that is a multi-gigabyte CAD package, a high-resolution structural drawing, or 4K drone footage of a construction site. Multiple files are packaged into a zip for download, but that process is lossless and does not change the files themselves.
WeTransfer gives you two access control options on all plans. You can add a password to a transfer so only recipients who know it can open the files, and you can restrict access to a specific list of email addresses so the download link works only for named individuals. For engineering teams handling confidential IP, restricted access also triggers a detailed notification each time someone downloads, giving you a clear record of who accessed which files and when. Both settings can be applied before sending or adjusted afterwards from your transfer details page.
