Message and Attachment Size Limits in Gmail
Gmail processes messages up to 25 MB in size.
Sending messages larger than 25 MB from Gmail yields an error.
Messages sent to your Gmail account that exceed the limit bounce back to the sender.
Still, there are options for sending large files through Gmail.
Finish composing your message, then selectSend.
SelectSendagain if asked to grant access to the file.
The recipient receives a link to download the file or view it in a web surfing app.
As an alternative, split the file into smaller chunks or usea file sharing service.
