Why email can't send it
Gmail's limit for personal accounts is 25 MB of attachments per message; anything bigger is removed and replaced with a Google Drive link. Other providers sit in the same range or lower. So the question isn't how to attach a large file — it's which link to send instead.
Your free options, compared
| Method | Size | Account needed | Downside |
|---|---|---|---|
| Email attachment | About 25 MB | Yes (yours) | Anything bigger turns into a cloud link anyway |
| WhatsApp, sent as a document | Up to 2 GB | Both sides on WhatsApp | Copy stays on both phones and in backups |
| Cloud drive link | Your free storage quota | Yes (yours) | Link works until you remember to revoke it |
| Expiring download link (Transient Files) | Up to 1 GB per file | None | Deleted after 24 hours at most — by design |
Pick by how long the file should exist. For a hand-off that's done once the other person has it, an expiring link leaves nothing behind. For a file several people will keep working on, a cloud drive fits better.
Sending a 1 GB file, step by step
- Open the large-file upload page and choose the file — no account, no email address.
- Choose how long the link lives: 1, 12 or 24 hours, or until it's downloaded once.
- Keep the tab open until the upload finishes, then copy the link and send it by any chat or email.
- Several large files? Put up to 50 of them (2 GB in total) behind one folder link.
How long will the upload take?
Upload speed is usually the bottleneck, and it's often far lower than your download speed. A 1 GB file is about 8,000 megabits, so it takes roughly 13 minutes at 10 Mbps upload, under 3 minutes at 50 Mbps and about 80 seconds at 100 Mbps. Use Wi-Fi or a wired connection rather than mobile data for anything this size.
Zip it or not?
Compressing a folder into a ZIP bundles it into one file, but videos, photos and most archives are already compressed and barely shrink. Zip to keep files together, not to make them fit. For videos, the only way to get much smaller is re-encoding at a lower quality — which is exactly what a link lets you avoid.
What if the file is bigger than 1 GB?
Split it or use a service built for size. Tools like 7-Zip can split an archive into parts (for example 900 MB each) that you send as separate links or as one folder; the recipient needs all the parts to rebuild it. For multi-gigabyte projects that need to stay available for days, a cloud drive or a paid transfer plan is the honest answer.
