Like most other email providers, Gmail limits the size of messages and file attachments you can send and receive. Learn about Gmail attachment restrictions and how to get around them so that you can send large files using Google Drive.

Instructions in this article apply to the web versions of Gmail and the Gmail mobile app for iOS and Android.

Message and Attachment Size Limits in Gmail

Gmail processes messages up to 25 MB in size. This limit is applied to the sum of the message's text and the encoded attachment. Encoding makes the file size slightly larger, so if you have a file that is exactly 25 MB, it will not go through.

Trying to send messages larger than 25 MB from Gmail will yield an error. Messages exceeding the limit sent to your Gmail account will bounce back to the sender.

You can attach any file type of file, but the size limit rules out most video and audio formats as well as large PDF documents with hundreds of pictures. That said, there are options for sending large files through Gmail.

Sending and Receiving Larger Files with Gmail

The easiest way to work around message size limit is built-in to Gmail. You can send files using Google Drive while composing a message:

  1. Select the Insert files using Drive icon in the bottom toolbar (it looks like a triangle).
