How to send a large file as an attachment on Gmail

It’s very easy to send a file attachment through Gmail, even if the file is several gigas.

What is the maximum size of an attachment on Gmail?

You can send attachments up to 25MB in size. If you’re sending multiple attachments, their total size can’t exceed this limit. If your file is larger than 25MB, Gmail will automatically add a Google Drive link to the email instead of including the file as an attachment. The recipient can download the file. This way, they’ll be able to access the file, even if you delete the file from Google Drive.

Why does Gmail allow large files as attachments?


Gmail will automatically test whether the recipients of your email have sufficient access rights to the document. If not, Gmail will ask you to change the sharing options, without leaving your new mail creation interface.

Obviously, by offering such features to its hundreds of millions of Gmail users, Google hopes to get them even more used to always using its countless services. And not to go elsewhere, to for example (which offers the same functionality via its SkyDrive service) or to specialists in sending large files (, and others).

This system also requires the recipients of the email to have a Google account (to access the document on Google Drive). One more way to get Internet users used to use their Google account permanently.
