WhatsApp will send a file up to 2 GB — but only if you send it as a document. Send a video through the photo button and it is re-compressed and arrives visibly worse. That is the whole trick: send as a document to keep the original, and send a link when the file is over 2 GB.
Media versus document
This is the distinction that matters and the interface does not explain it.
Send as media (the photo/video button) means WhatsApp re-encodes to save bandwidth. A 4K clip arrives compressed and downscaled. For a family video that is fine — it is why it plays instantly. For anything you shot professionally, it is destroyed.
Send as document (the paperclip, then Document) means the file is transferred as-is. No re-encoding, no downscale, original quality.
To send a video at full quality, attach it as a document. On iOS you may need to save it to Files first. It is one extra tap and it is the difference between a deliverable and a preview.
The same applies to photos. Sent as media, images are compressed. Sent as a document, the original file arrives — which matters if you are sending anything that will be printed or edited.
Size limits
- Documents: up to 2 GB.
- Media: smaller, and re-compressed regardless.
Two gigabytes is a lot for a phone video and not much for anything shot properly. A minute of 4K in a camera codec can be several gigabytes on its own.
Above 2 GB
Send a link. Upload the file somewhere and paste the URL into the chat — the message is tiny and nothing gets re-encoded.
Almost anything clears WhatsApp's 2 GB document ceiling: SwissTransfer sends 50 GB free with no account (checked 1 August 2026), and even the smallest free tiers match the 2 GB you already had. What you gain over WhatsApp is that the file is not also sitting in a chat thread on two phones. The full comparison covers who offers what.
This is also the better answer for a folder of files. WhatsApp has no concept of folder structure, so a shoot sent as thirty separate documents arrives as thirty separate documents, in whatever order they finished uploading. Sending a folder properly is its own problem.
Things worth knowing
Compression is not reversible. If you sent as media and it looks bad, you cannot fix it at the other end. Send it again as a document.
Your phone keeps a copy. Files sent and received are stored locally, and depending on settings, backed up. If you routinely move client material through WhatsApp, that material is on your phone and in your backup, which is worth a thought if the phone is ever lost or the files are sensitive.
Backups are not covered by the same protections as messages in transit. WhatsApp messages are end-to-end encrypted in transit. What happens to a file after it lands on a device — in the camera roll, in a cloud backup — is governed by that device's settings, not by WhatsApp. For anything genuinely confidential, that distinction matters.
It is a poor archive. Chats get cleared, phones get replaced, and media gets auto-deleted by storage-management settings. If a file needs to exist in six months, it needs to be somewhere else too.
Sending from a phone generally
If you are on a phone rather than at a desk, WhatsApp is one of several options and not usually the best one for large files. Sending large files from an iPhone covers Mail Drop, AirDrop, iCloud links and the browser route, and which of them keeps the original.
Quick answers
Video to a friend, quality does not matter. Send as media. It is instant.
Video where quality matters. Send as a document, under 2 GB.
Over 2 GB. Upload and send a link.
Client work. Send a link, not a WhatsApp file. You get an expiry, a link you can revoke, and a delivery that is not sitting in a chat thread either of you might clear — secure sharing is what that looks like.
Anything with someone else's personal data. Not WhatsApp. Use a link with an expiry and think about who ends up holding a copy — on a phone, that is usually more people than you intended.
