Gmail Attachment Size Limit: How Big Can Files Be? (2026)
Gmail lets you send attachments up to 25 MB total per email and receive up to 50 MB. If a file is bigger than 25 MB, Gmail automatically uploads it to Google Drive and inserts a link instead. Here’s exactly how the limits work.
The Limits at a Glance
Sending
- Up to 25 MB total — that’s all attachments in one email combined, not per file
Receiving
- Up to 50 MB
Google Drive sharing
- Share files up to 10 GB via a Drive link
How the 25 MB Limit Is Measured
The 25 MB cap is the combined size of every attachment in a single message — not a per-file limit. Three 10 MB files in one email exceed the cap; one 24 MB file is fine.
When a file (or the total) goes over 25 MB, Gmail doesn’t reject it. Instead, it uploads the file to your Google Drive and drops in a Drive link automatically, so the recipient downloads it from there. This is why you can effectively “send” much larger files than 25 MB — Drive does the heavy lifting.
How to Send Files Larger Than 25 MB
- Use a Google Drive link. Gmail does this automatically for oversized files, or you can attach from Drive manually using the Drive icon in the compose window.
- Zip or compress the files first to squeeze under 25 MB.
- Share via a cloud link (Drive, Dropbox, etc.) and paste the URL into the email body.
- Split large files across multiple emails if compression isn’t an option.

"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
