Gmail caps email attachments at 25MB. That's smaller than most photos taken on a modern phone, and a fraction of a short 4K video. Here's what the limits are across every email provider — and how to bypass them entirely.
| Email Provider | Attachment Limit | Built-in Workaround |
|---|---|---|
| Gmail | 25MB | Google Drive link (needs Google account) |
| Outlook / Hotmail | 20MB (free) / 25MB (M365) | OneDrive link |
| Yahoo Mail | 25MB | Dropbox or Drive link |
| Apple Mail / iCloud | 20MB | Mail Drop — files expire in 30 days |
| ProtonMail | 25MB | None built-in |
| Seyfr (P2P, no email) | No limit | Goes directly — no email needed |
Seyfr is a peer-to-peer file transfer app. Instead of attaching a file to an email, you open Seyfr on your phone, generate a transfer QR code, and the recipient opens it on their device. Files go directly from you to them — no email, no cloud upload, no size limit.
Free on Google Play (Android) and the App Store (iPhone). No account required.
The QR code is your transfer ticket. Share it with the recipient via text, email, or show it on screen.
They open it in any browser on their phone, iPad or Android tablet, Mac, Windows PC, or Linux machine. No app install needed on their end.
Files transfer at full speed directly to the recipient. No upload wait, no size cap, no compression.
| Feature | Seyfr | Google Drive Link | WeTransfer |
|---|---|---|---|

| File uploaded to cloud | No — direct | Yes | Yes |
| Recipient needs account | No | Sometimes | No |
| Files expire | No | No | Yes — 7 days |
| End-to-end encrypted | Yes | No | No |
| Price | Free | Free (15GB limit) | Free (2GB) / Paid |
Send files of any size — directly to any device — with no email, no cloud, no account.
Gmail's attachment size limit is 25MB. Files larger than 25MB cannot be attached directly — Gmail offers to insert a Google Drive link instead, which requires uploading to Google's servers first.
The Gmail workaround is a Google Drive link (up to 15GB). To send large files without any cloud service, use Seyfr — no email, no upload, no size limit. Works from Android, iPhone, Windows, Mac, and Linux.
Outlook.com free accounts have a 20MB limit. Microsoft 365 accounts have a 25MB limit. Both fall far short of modern file sizes like 4K video or RAW photos.
Use Seyfr. It transfers video files at full original quality — no re-encoding, no compression. A 4K video from your phone arrives on the recipient's device exactly as recorded.
Yes — Seyfr. Open Seyfr on your phone, get a QR code, share it with the recipient, and your file transfers directly. No Google account, no Drive, no email, no size limit.
