WeTransfer sends a zip that expires. MDB Builder delivers a structured Manufacturing Data Book your client can open, review, approve and trace — with no link expiry. An honest, side-by-side comparison.
WeTransfer is a fast way to send a large file, and many teams use it as the final step of an MDB handover. But it ends at download: the client gets a zip with an expiring link, no structured book, no online review or approval, and no record of who opened it. MDB Builder delivers the Manufacturing Data Book as a hosted, reviewable deliverable — the client navigates it by chapter, approves it online, and the link does not expire. WeTransfer moves bytes; MDB Builder hands over a deliverable.
For a quick, no-friction transfer of a large file to someone outside your organisation, WeTransfer is hard to beat — and that is exactly what it was built for.
A Manufacturing Data Book is a formal deliverable that the client has to review, approve and keep. WeTransfer treats it as bytes to move once. The gap is everything that happens after the file lands.

Keep WeTransfer for what it is good at — firing off a large file to a contact when there is no formality attached. When the file in question is the Manufacturing Data Book itself, the handover is the point: the client needs to review it, approve it and be able to find it again later.
MDB Builder turns that handover into a hosted, reviewable deliverable with a lasting link and a full audit trail — so the last step of the project is a sign-off, not just a download that expires next month.

Yes, and it is a common last step: assemble the MDB, then send the PDF via WeTransfer. It works for the transfer itself, but it stops there. The client receives a file to download — there is no structure beyond what you uploaded, no online review or approval, no audit trail of who opened it, and the link typically expires. For a formal quality deliverable that the client has to review and sign off, that is usually not enough on its own.
The minimum is a single, bookmarked PDF with a cover page, table of contents and clearly chaptered sections, named to the client's transmittal convention. You can produce that PDF and send it by WeTransfer or email, but the client then has no structured way to review or approve it. MDB Builder delivers the same MRB as a hosted, reviewable deliverable: the client opens it online, navigates by chapter, comments in context and approves — and you keep the audit trail and revision history.
A large quality dossier exceeds email limits, so teams reach for WeTransfer or similar transfer services. Those handle the bytes, but the recipient still just gets a download whose link expires. MDB Builder hosts the assembled dossier so the client can open and review it without a giant download or an expiring link, and you can re-issue a revised version in place rather than sending a fresh multi-GB transfer each time.
For delivering Manufacturing Data Books, yes — it replaces the send-a-zip step with a structured, reviewable, traceable deliverable. For ad-hoc transfers of unrelated large files, WeTransfer remains convenient. The two are complementary: WeTransfer for quick one-off file sends, MDB Builder for handing over the MDB itself.
On most WeTransfer plans, yes — shared links and the files behind them expire after a set period, after which the client can no longer download the dossier. For a quality deliverable that may be referenced months or years later during an audit, that is a real limitation. An MDB delivered through MDB Builder stays available to the client, with its revision history intact.
