Video is where "send large files" stops being theory. A few minutes of 4K footage is bigger than any email limit, and most chat apps quietly shrink the video to save bandwidth. This guide explains how to send large video files in full quality — from a phone or a computer — and which method fits which size.
Why are video files so large?
A video file's size is its bitrate multiplied by its length. Phones and cameras record at high bitrates so that the image survives editing. The math is simple — Mbit/s × seconds ÷ 8 = MB:
| Bitrate | 1 minute | 10 minutes | 1 hour |
|---|---|---|---|
| 20 Mbit/s (typical HD) | 150 MB | 1.5 GB | 9 GB |
| 50 Mbit/s | 375 MB | 3.75 GB | 22.5 GB |
| 100 Mbit/s (typical 4K) | 750 MB | 7.5 GB | 45 GB |
| 400 Mbit/s (high-end / editing codecs) | 3 GB | 30 GB | 180 GB |
So a ten-minute 4K clip is already more than double the WeTransfer free limit, and a wedding or a shoot day runs into hundreds of gigabytes.
Why does video lose quality when I send it?
Because many channels re-encode it. Messaging apps compress photos and videos sent as regular media to save data — WhatsApp's own help notes that shared media is usually compressed and may be lower quality than the original. Social networks re-encode everything on upload.
You keep full quality when the channel treats the video as a file, not as media: an email attachment, a cloud link, a transfer service, a messenger's "document" option, or a direct transfer. Compression is not something you need to accept — it is a side effect of the channel.

How do I send large video files from a computer?
On a Mac or PC the easiest full-quality route is a direct link:
- Open StrongFolder and add the video files — or the whole project folder with its
Footage,AudioandExportssubfolders. - Copy the link and send it to the editor or client.
- Keep the tab open while they download. The video goes straight from your disk to theirs; it is never stored on a server.
Because nothing is uploaded first, the recipient starts receiving the first file within seconds instead of waiting for your whole upload to finish.

How do I send a large video from my phone?
- iPhone to Mac or iPhone: AirDrop keeps the original quality and is fast when both devices are nearby.
- Android to Android or Windows: Quick Share works between nearby devices; for other combinations see our AirDrop alternative for Windows and Android.
- To anyone, anywhere: open strongfolder.com in the phone's browser, pick the video from your gallery or files and share the link. Keep the browser in the foreground and the screen on — phones pause background tabs to save battery, and the video is streaming from your phone.
- In a messenger: use the "document" or "file" option rather than the gallery button, so the app sends the file instead of a compressed copy.
From a computer to a phone, show the link's QR code on screen and scan it with the phone camera. Every link also has a QR code, handy for sending from a computer to a phone. Details in PC to phone file transfer.
How long will it take?
Transfer time depends on the sender's upload speed: size in GB × 8,000 ÷ Mbit/s = seconds. A 7.5 GB ten-minute 4K clip takes about 20 minutes at 50 Mbit/s and about 10 minutes at 100 Mbit/s. A 45 GB hour of 4K takes about 2 hours at 50 Mbit/s. A wired connection and a laptop on power make a long transfer far more reliable than Wi-Fi on battery.
Should I compress the video first?
Only when the recipient does not need the original. A smaller H.264 or H.265 export is fine for a quick approval or for social media. For editing, colour grading, archiving or delivery to a client, send the master: every re-encode throws away detail you can't get back.
Zipping a video folder doesn't help either — video is already compressed, so the ZIP is almost the same size and just adds packing and unpacking time.
When is StrongFolder not the best choice for video?
- You need to send and go offline. A transfer service or cloud link keeps the file available after you close the laptop.
- The client wants to watch and comment in the browser. Review platforms and cloud drives play video online; StrongFolder delivers files for download.
- You have several terabytes of rushes. A shipped SSD is often faster than any upload.
- Your phone can't stay awake for the whole transfer. Copy the video to a computer first, or use a cloud app that uploads in the background.
Summary
To send large video files without losing quality, send the original file through a channel that doesn't re-encode it. Use a messenger's document option or a transfer service for a single clip of a few GB, a cloud drive for long-term client access, and a direct P2P link for large clips and whole footage folders.
