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 through Iroh peer-to-peer networking — 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 move from you to them — no email, no JITPOMI cloud-drive upload, no fixed application transfer cap.
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 the SEYFR app on their phone, iPad or Android tablet, Mac, Windows PC, or Linux machine. The SEYFR app is required on the receiving device.
Files transfer at a speed determined by the devices and network path. SEYFR does not intentionally recompress them and has no fixed application transfer-size cap; device, platform, storage, network, and relay limits still apply.

Send files of many sizes — directly to a supported device — with no email, no JITPOMI cloud drive, 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.
Cloud-storage limits depend on the provider and plan. SEYFR can transfer a large file between supported devices without email, a SEYFR account, or a JITPOMI cloud-drive upload. It has no fixed application cap, but device, storage, platform, network, and relay limits still apply.
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, without intentional recompression. 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 using Iroh peer-to-peer networking. No Google account, no Drive, no email, no fixed application transfer cap.
