How to share large files on a Mac without the file bouncing

AirDrop, if the other person is in the room

For Mac to Mac or Mac to iPhone, AirDrop is the fastest thing on the list and has no practical file size limit. It goes peer to peer over Wi-Fi and Bluetooth, so a 5GB video moves at local network speed rather than upload speed.

Open Finder, drag the file onto the recipient in the AirDrop sidebar, they accept, done. There's no account to make and nothing uploads anywhere.

The catch is obvious and total: they have to be an Apple user, nearby, with AirDrop discoverable. Which rules out most work. I use it constantly for moving things between my own devices and almost never for sending anything to anyone else.

Mail Drop handles up to 5GB and nobody uses it

Mail Drop is built into Apple Mail. Attach a file that's too big, and macOS offers to send it via Mail Drop instead. The recipient gets a download link in the email rather than an attachment, so it lands in any inbox on any platform.

Per Apple's Mail Drop limits page, you can send up to 5GB, recipients have 30 days to download, and the attachments don't count against your iCloud storage, though there's a 1TB Mail Drop ceiling across everything you've uploaded.

Five gigabytes, free, already installed, and it works fine when the person on the other end is in Outlook or Gmail. For a one-off it's hard to beat, and the only reason more people don't use it is that Apple never bothered telling anyone it exists.

Two things to know. It only appears in Apple Mail, so if you live in Gmail's web interface you'll never see the prompt. And the 30-day window is real, which makes it wrong for anything a client might come back to in month two.

iCloud Drive for the file you'll send more than once

Drop the file in iCloud Drive, right-click, Share, Copy Link. You get a URL you control, and you can change or revoke access later.

The limit here is your iCloud storage plan, which for most people means 5GB free and therefore not much. If you're already paying for iCloud+ it's the most frictionless option on a Mac, because the file is somewhere you'd have put it anyway.

Same pattern as Google Drive, really. I compared the general link-sharing approaches in file to URL if you want the non-Apple options too.

WeTransfer for when you need it to just work on someone else's machine

WeTransfer stays popular because it asks nothing of the recipient. They click, the file downloads, and nobody has to make an account.

The free tier has tightened, though. WeTransfer's plan limits page currently puts free users at up to 10 transfers or 3GB total in any 30-day rolling window, so it's no longer the bottomless free option it was when everyone got into the habit.

Fine for a client who you suspect will struggle with anything more complicated. Wrong if you send large files weekly.

Compressing first is underrated and takes four seconds

Right-click, Compress. macOS makes a .zip and it costs you nothing to try.

It won't help much with video or already-compressed images, but a folder of PSDs, a pile of Word documents or a chunky PDF will often drop enough to sneak under a limit. I've watched people spend ten minutes signing up for a transfer service to send something that would have zipped down to 18MB.

If you go this route, be aware that some corporate mail filters strip or quarantine zip attachments, which I wrote about in sending zip files.

Big and important are different problems

Everything above solves size. None of it solves the thing that actually goes wrong with an important document, which is that you have no idea what happened to it after you hit send.

When I was doing go-to-market at a data SaaS I'd send a 40MB report to a prospect, watch the transfer succeed, and then spend a week with absolutely no information at all. A successful upload tells you something about your broadband and nothing whatsoever about your deal.

If the file is a proposal, a deck or a report that a decision hangs on, use something that tells you what the reader did with it. That's the category DocSend, Papermark and LiveDocument live in, and it's a different purchase from a transfer tool. We built LiveDocument so you can record a video walkthrough over a PDF or an image and share both behind one link, with page-level analytics showing which pages held attention. It is not a file transfer service and it won't move your 5GB video folder, so for that job Mail Drop is still your answer and I'd use it myself.

What I'd actually do with a 900MB folder

Say a designer has sent me 900MB of brand assets and I need to get them to a client by this afternoon.

If the client were sitting across the table I'd AirDrop it and be done in ninety seconds. They're not, so it's Mail Drop: attach the zipped folder in Apple Mail, let macOS swap it for a link, send. It lands in their Outlook looking like a normal email, they've got 30 days, and I haven't signed up for anything or eaten into my iCloud storage.

The only thing that would change my mind is if I expected them to keep coming back to those files over the next few months. Then it goes in iCloud Drive or Google Drive instead, because the 30-day clock would eventually break the link and I'd be the one re-sending it.
