How to send large files via email, without paying

The results for how to send large files via email are mostly transfer services, and the advertising rate on this search tells you why. Before any of them: both of the two commonest mail accounts in the world already solve this, free, and one of them does it without being asked.

Gmail

It does it for you

25 MB

Google: “For personal Gmail accounts, the limit is 25 MB.” Above that, nothing fails — “Gmail automatically removes the attachment and adds it as a Google Drive link in the email.”

Which means a great many people searching this have already been handed the answer and did not recognise it as one.

Apple Mail

Mail Drop, free with iCloud

5 GB

Apple: “With Mail Drop, you can send attachments up to 5GB in size.” It works from Mail on a Mac, on an iPhone or iPad, and from iCloud.com in any browser.

And the detail that makes it usable: “All files types are supported and attachments don’t count towards your iCloud storage.”

The limit that matters is not yours

Every guide to this subject tells you your own provider’s ceiling. Apple names the one that actually decides whether the message arrives: “The recipient’s email app may have a smaller message size limit that prevents the attachment from being delivered.”

You can be comfortably inside your own allowance and still have the file bounce, because the person receiving it is on a company mail server with a stricter rule. A link is immune to this and an attachment is not — which is the practical argument for sending a link even when the file would technically fit.

Three things to check before you rely on it

30 daysApple: “After you’ve sent an email, the recipients will have 30 days to download the Mail Drop attachments.” A link found in an old thread will be dead.
FoldersApple lists an “uncompressed folder is attached to the message” among the reasons Mail Drop refuses. Compress the folder first and it goes.
PermissionsA Drive link sends fine and opens for nobody if the sharing setting is wrong. The message goes; the file does not.

That last one is the commonest silent failure in this whole subject. The email arrives, the recipient clicks, and is asked to request access — which they may or may not do, and which you will not learn about unless they tell you.

So the order to work through is short, and it costs nothing. Try attaching it. On Gmail, anything over the limit becomes a Drive link by itself. On Apple Mail, you are offered Mail Drop when the message exceeds what your provider accepts — Apple: “Mail will ask you to send the attachments using Mail Drop.” If neither applies, put the file in whatever cloud storage came with your account and send the link deliberately rather than accidentally.

A transfer service earns its place in one situation: sending something to somebody you have no shared platform with, where a link that expires is a feature rather than a problem. That is a real case. It is not the case most people are in when they search this, which is emailing a video to a colleague or a folder of photographs to a relative — and for that, the tools are already in the account.

The way people ask sorts them by what they are sending. How to send a large file through email and how do you email large files are the general version. How to send large video files is the commonest specific one, and it is also the case where compressing first often removes the problem entirely. And send big files free is somebody who has already been quoted a price for something their mail account includes.

One habit is worth more than any of the routes above. Before sending anything large, ask whether it needs to be large. A video exported at a sensible size, a scan made at a sensible resolution, a set of photographs that are not all full-resolution originals — each of those turns a transfer problem into an ordinary attachment, and none of them requires a service.

Where to start

Four ways in.

“I use Gmail.”
It is above. Then links and permissions
“I use Apple Mail.”
Also above. Then mail drop limits
“It is a video.”
Go to making it smaller
“It has to be private.”
Read what you are sharing

Sending a link is the answer to almost all of this, and the one way it fails is a setting rather than a size.

Making it smaller

Often the real answer. A file that fits needs no service, no link and no expiry date.

What this tower will not do

It will not open with a transfer service. Two of the largest mail providers include a free answer, and one of them applies it automatically.

It will not quote only your own size limit. Apple documents that the recipient’s limit can be smaller, and that is the one that decides whether the file arrives.

And it will not rank the transfer services yet. That needs the same files — a long video, a folder of raw photographs, a document with a deadline — through each of them, with what each keeps and for how long published alongside. What holds instead is simple: the limits on this page are quoted from Google’s and Apple’s own documentation.
