How to Send Large Video Files (Without the Email Size Limit)
Product screenshots on this page show the current SEYFR 1.x interface while 2.0 is in development.
Written by JITPOMI, the team that builds SEYFR.
Email services impose attachment limits, while high-resolution video files can be much larger. Here is how to transfer a selected video file wirelessly between supported devices. SEYFR has no fixed app transfer cap, but device storage, platform limits, and network conditions still apply.
Keep the project together
Move the folder—not dozens of separate uploads.
When footage, audio, graphics, and project files belong together, select the folder and send its contents in one transfer. SEYFR preserves the relative paths of supported folder transfers.
The Email Attachment Size Limit Problem
No email provider will let you attach a large video. Their limits haven't meaningfully increased in years:
| Service | Attachment limit |
|---|---|
| Gmail | 25 MB |
| Outlook | 20 MB |
| Yahoo Mail | 25 MB |
| iCloud Mail | 20 MB |
| Seyfr | No fixed app cap* |
SEYFR 1.x UI
For context: a 1-minute 4K video from an iPhone records at about 400MB. A single 4K YouTube export is typically 1–5GB. A 10-minute Android 4K video is 2–6GB. Email is simply not the right tool for video.
How to Send Large Video Files with Seyfr (Free)
Seyfr transfers files using peer-to-peer networking between devices over Wi-Fi — no upload, no email, no JITPOMI cloud drive. Transfer time depends on the devices, network path and connection quality.
Install Seyfr on both devices
Download and install Seyfr on the sending device (iPhone or Android) and the receiving device (Windows, Mac, or Linux).
Select Send on the sender
On a phone, select Send, choose Videos, and select the video. On a desktop, select Send and drag the video onto the S, or click the S and choose it in the file picker. Seyfr then generates a QR code and token to share.
Open Receive on the receiver
On a desktop receiver, select Receive, paste the token, optionally choose a destination folder, and click Receive. On a phone receiver, select Receive, scan the QR code or paste the token, click Receive, then save the video to Photos.

How to Send a Large Video from Android to Mac
Android to Mac is the hardest combination — Android File Transfer doesn't support it reliably, and AirDrop only works with Apple devices. Seyfr solves this completely:
- Install Seyfr on both your Android phone and Mac
- Open Seyfr on Android, select Send, and choose your video file
- Open Seyfr on Mac, select Receive, paste the token, and optionally choose a destination folder
- Click Receive — the video transfers using peer-to-peer networking without intentional recompression
Transfer speed on a 300Mbps home Wi-Fi: depends on the devices and connection.
How to Send a Large Video from iPhone to Mac
iPhone records video in HEVC (H.265) which is very efficient — but 4K Cinematic Mode videos from iPhone 16 Pro still reach 3-6GB for a 3-minute clip. AirDrop is the native option but requires both devices. Seyfr is a alternative:
- Install Seyfr on both your iPhone and Mac
- Select Send on iPhone, choose Videos, and select the video
- Open Seyfr on Mac, select Receive, paste the token, and optionally choose a destination folder
- Click Receive—SEYFR transfers the selected file without intentionally recompressing or re-encoding it
How to Send a Large Video from iPhone to PC (Windows)
iPhone to Windows is harder than iPhone to Mac because Windows has no AirDrop. iTunes is the traditional option but it's slow and cumbersome. Seyfr:
- Install Seyfr on both your iPhone and Windows PC
- Select Send on iPhone, choose Videos, and select the video
- Open Seyfr on your PC, select Receive, paste the token, optionally choose a destination folder, and click Receive
Works on Windows 10 and Windows 11 with the native Seyfr desktop app.
How to Send a Large Video from Android to PC
Android to PC via USB requires drivers and MTP protocol which often fails. Seyfr does it wirelessly:
- Install Seyfr on both your Android phone and Windows PC
- Select Send on your Android phone, choose Videos, and select the video
- Open Seyfr on your PC, select Receive, paste the token, optionally choose a destination folder, and click Receive
Why Not Just Use WhatsApp or Messenger?
Messaging-app behavior depends on the send mode and current service limits; media modes may recompress content, while document modes can behave differently. Check the current service documentation.
SEYFR does not intentionally recompress or re-encode the selected file. verifies received content against its BLAKE3 content hash.
Send the file that every other app says is "too large."
Stop uploading your own files just to download them again. SEYFR transfers directly between devices with no fixed application size cap.
Frequently Asked Questions
What is the Gmail attachment size limit?
Email and cloud-storage limits vary by provider and plan. For a large video, SEYFR offers a no-account transfer: stop uploading your own files just to download them again. Send the file directly peer-to-peer.
How do I send a video that is too large for email?
Send the file that every other app says is "too large." Stop uploading your own files just to download them again. Use SEYFR to transfer the video directly to the recipient's device. Your devices don't have to be on the same Wi-Fi.
Does Seyfr compress videos?
No. Seyfr sends files bit-for-bit identical. Your 4K ProRes video, your RAW footage, your lossless audio — all arrive at exactly the quality you recorded. Nothing is compressed, re-encoded, or reduced.
How fast does Seyfr transfer large videos?
Transfer speed depends on your Wi-Fi network. On a typical 300Mbps home Wi-Fi, Seyfr transfer time depends on the devices, network path, relay use and connection quality.
Does Seyfr work without internet?
SEYFR does not require a cloud-storage upload step. A relay helps the devices connect and steps back when a direct path works. If no direct path can be established, it forwards the end-to-end encrypted transfer without reading or storing the video.
