Gmail Attachment Size Limit: How to Send Large Files via Gmail?

The Gmail max attachment size has remained unchanged at 25MB for years. This is to avoid overloading your limited Gmail inbox and to avoid stressing your mail server with large files. If you force Gmail to send attachments larger than 25MB, they must be sent as a Google Drive link automatically generated by Gmail. Honestly, this is the easiest way to send files that exceed Gmail's attachment limit. However, even if you try to send a file smaller than 25MB, you may still find that it doesn't work because it exceeds the limit of the MIME standard. In other words, the actual attachment size you allow to send is less than 25MB.

But don't lose heart. The following two sections provide you with two useful workarounds to bypass the Gmail size limit. Read on.

The Google Drive link auto-generated by Gmail gives us a hint that we can send our large files as a downloadable link embedded in our email. And we need to rely on some cloud storage services like Google Drive, One Drive, and Dropbox in this method to help turn the files into the link. However, instead of creating links on the spot when composing emails (suitable for people having rich time), this approach is to prepare file links beforehand so you can attach it to your email immediately. Here we also take Google Drive as an example:

Step 1. Sign up for Google Drive with your Google account. You’ll receive a 15GB free storage space.

Step 2. In Google Drive, click on the + New button on the upper left corner of the page to create a folder or directly upload your single file or folder file into Google Drive.

Step 3. Go to Gmail. At the top left, click Compose.

Step 4. In the Compose page, click the Google Drive icon at the bottom menu row and select the files you want to attach. Then click Insert.

Step 5. Click Send.

Another way to overcome the Gmail attachment size limit is to compress the file using WinRAR. This approach is suitable for files that are around 30MB in total. Here is the detailed process:

Step 1. Install WinRAR on your PC.

Step 2. Put all the files you want to attach in one folder.

Step 3. Right-click on the folder > Send to > Compressed (zipped) folder. You’ll get a zipped file that is 30 or 40 percent smaller than the original files.
