Google allows up to 25 MB size of files to be exchanged through e-mail.

Google's email service, Gmail, has certain limitations on the size of files that can be sent or received through email. The maximum file size limit for attachments in Gmail is 25 megabytes (MB). This means that any file larger than 25 MB cannot be directly attached to an email and sent through Gmail. However, there are alternative methods to send larger files using Google Drive or other file-sharing services.

Here are the file size limits for different types of files in Gmail:

• Attachments: The maximum file size limit for attachments is 25 MB. This includes files like documents, images, videos, presentations, etc.


• Google Drive: If you have larger files to share, you can upload them to Google Drive and share the link in your email. Google Drive allows you to store and share files up to 15 GB in size.


• Compressing files: If you need to send larger files as attachments, you can compress them into a ZIP file to reduce the overall file size. This can be done using software like WinRAR or 7-Zip.

It's important to note that even though Google allows attachments up to 25 MB, some email providers or recipients may have lower attachment size limits. In such cases, it's advisable to use alternative methods like Google Drive or file-sharing services to send larger files.
