How To Send Large Files Through Gmail
Gmail’s maximum attachment size limit of 25 MB applies to both single and multiple files.
💡 Tip: If you have email accounts in different mail service providers, check out how to send large files via email in the most popular ones.
A file greater than the recommended size will be converted into a Google Drive link. The recipients of your email can then click this link and download the file.
Sending large files through Gmail with Google Drive
If your file is over Gmail’s 25 MB limit, the most reliable method is to send it through Google Drive. Instead of attaching the file directly, Gmail inserts a Drive link so your recipient can access the file without bounce-back errors.
- Open Gmail and click Compose.
- Click the Google Drive icon at the bottom of the message window.
- Upload your file (or select one already in Drive).
- Choose the Drive link (not “Attachment”).
- Confirm sharing permissions so recipients can open the file.
- Send your email.
This method is faster than splitting files into multiple email messages and helps preserve original file quality. It’s also easier to resend later because you can reuse the same Drive link.

How to send large files via Gmail without Google Drive
Using Google Drive is the easiest way to send large files. However, if you don’t want to use Drive, you can do the following to reduce file size before sending:
- Archive it
To make the file smaller, zip it. Spreadsheets and documents benefit most from this, but media files might not get much smaller.
- Reduce video size
You can re-export videos at a lower resolution (like 1080p to 720p), a lower bitrate, or for a shorter time. Even small changes to the bitrate can make a big difference in file size.
- Optimize images
Attachments often fail because the images are too big. Change the size, lower the quality of the export a little, and save in formats that work well, like JPG (for photos) or WebP if they work.
- Divide the files among several emails
Divide a big file into manageable chunks and send them in different messages. It is slower and more difficult for recipients to handle, but it does work.
- Use a file transfer service
Send a download link via Gmail after uploading the file to a file transfer website. For very large files, this is frequently the simplest non-Drive method.
- Get rid of unnecessary content
Before exporting, get rid of duplicate images, hidden slides, old revisions, or extra pages. Sending only the final files keeps attachments smaller and cleaner.
- Before sending, minimize the size of the file
To make the final file fit within Gmail's limit, export documents in lighter formats (like PDF), reduce the image resolution, or shorten videos.
📌 Note: Switching to another email provider is unlikely to solve attachment size issues, as most services enforce similar limits. Gmail, Yahoo Mail, AOL Mail, and Proton Mail allow up to 25 MB per email, Outlook permits 20 MB, and Hotmail supports only 10 MB—meaning large files will exceed the threshold on most platforms.
Use Clean Email To Simplify Email Management
If your inbox is full of large messages, cleaning it first can make sending and receiving attachments much easier.
Clean Email helps you quickly find heavy emails, remove old clutter, and keep new buildup under control with automation. It’s available on macOS, mobile, and the web, so you can manage storage from any device.
Instead of having to sort through thousands of messages by hand to keep free space over time, you can use bulk actions with just a few clicks.
Then, set up Auto Clean rules to keep processing messages that fit size, age, sender, or category filters (like old big promos) so that storage space doesn't fill up again.
These and other features work together to make a cleanup system that can be used over and over again to keep Gmail storage healthy and make attachments easier to use.
