How to send large video files

By Hein de Wilde··4 min read

Video breaks every size limit, so the practical answer is a transfer service link rather than anything email-based — and the important decision is made before you upload: send a compressed preview for review, and the original for delivery. Compressing a master to fit under a free tier is the mistake that costs the most.

First, know your actual number

People guess video sizes wrong by an order of magnitude. The same one-minute clip can be 200 MB or 5 GB depending on how it was recorded:

  • Heavily compressed (H.264/H.265 from a phone or a web export): roughly 60–200 MB a minute for 4K.
  • Camera codecs at higher bitrates: several hundred MB a minute.
  • ProRes 422 HQ: roughly 5 GB a minute for 4K.
  • Camera RAW: more again.

The full arithmetic is here. Check the file before choosing a method, because a ten-minute ProRes cut is around 50 GB and lands in an entirely different bracket from a ten-minute phone video.

The two-file habit

This is the single most useful thing in this article and almost nobody does it consistently.

Send a preview for review. Send the original for delivery.

A viewing-quality H.264 export of a ten-minute cut is a couple of gigabytes, uploads in minutes, plays in a browser, and is entirely adequate for someone to say "the music is too loud at 4:20". Then you make the fix once and send the master a single time.

The alternative — uploading 50 GB, waiting, getting a note, re-uploading 50 GB — is how a day disappears. The saving here is larger than any difference between transfer services.

Choosing where to send it

Under a couple of gigabytes, anything works. Above that, free tiers diverge sharply. From each company's own documentation:

  • SwissTransfer: 50 GB free, no account, deleted after 15 days (checked 1 August 2026). Note that archives over 10 GB have to be downloaded file by file, which is fine for one video and awkward for a folder.
  • Yungle: 10 GB per transfer, unlimited transfers, no ads (mine).
  • Filemail: 5 GB free; Pro goes to 250 GB per transfer (checked 1 August 2026).
  • Smash: 2 GB free with priority; above that queued rather than refused (checked 1 August 2026).
  • WeTransfer: 3 GB free across a rolling 30 days (checked 31 July 2026).
  • Dropbox Transfer: 2 GB free, 30 days (checked 31 July 2026).

For anything above about 50 GB, the ceiling stops mattering and one property takes over.

Above 50 GB, resumability is the only thing that matters

A 100 GB upload takes hours. Your laptop will sleep, your router will restart, or your connection will drop. The question to ask is: does an interrupted upload resume, or start again?

If it restarts, the advertised limit is meaningless — you will never finish. Test this before you trust a service with a real deliverable: start a large upload, disconnect deliberately, reconnect, and see what happens. The technical version of why this is hard.

Other habits at this size:

  • Upload overnight, wired if possible.
  • Disable sleep on the machine doing the uploading.
  • Do not upload from a laptop you need to carry somewhere.

What not to compress

Never re-encode the deliverable to fit a limit. If the ceiling is forcing you to export the master at a lower bitrate, you are damaging the thing you are being paid for in order to avoid using a different service.

Re-encoding is lossy and cumulative — each generation loses quality permanently, and it is most visible exactly where clients notice: gradients, skin tones, motion.

Compress the preview. Deliver the original. How to make a video file smaller covers what actually works when compression is the right call.

If you are delivering, not just sending

A finished job is rarely one file. It is the graded master, a web export, the stems, the subtitles and some stills. Sent as loose files they arrive as a pile; the client emails you asking which is which.

Two things fix that:

Keep the folder structure. Whether a service preserves it varies more than you would expect, and it is worth knowing before you upload 80 GB.

Make it last longer than a fortnight. Clients come back months later. If your delivery expired in fifteen days, that is a re-upload of the whole thing at your cost — which is the most common expensive version of this problem.

For repeat client work, the video editor comparison covers which services handle the delivery half rather than just the upload half.

Quick answers

Ten-minute phone video, one-off. Any free tier. Do not overthink it.

Ten-minute ProRes cut, about 50 GB. SwissTransfer free if the recipient can handle the file-by-file download, or a paid plan. Upload overnight and check resumability first.

A full delivery folder with masters and stems. You need structure preserved and a single-archive download, which narrows the field considerably.

Multiple terabytes. Post an encrypted drive. It is faster and it is standard practice.
