How to compress a video for WhatsApp

  1. Drop the video in. MP4, MOV, WebM or MKV.
  2. The target is already set to 16 MB. Leave it, or change the number if your case is different. Resolution and frame rate caps are optional.
  3. Download and send. The file lands at or under 16 MB and sends as a video, not as a document.

What WhatsApp does to videos

The 16 MB rule
Videos over 16 MB are refused or sent as a document with no preview and no inline playback. Under 16 MB they send as a normal video message.
WhatsApp compresses again
WhatsApp re-encodes every video it sends and it is not gentle. Sending a clean 1080p file at 16 MB gives its encoder something good to work with, which looks better than sending a 4K file and letting it crush it.
Documents are the escape hatch
A file up to 2 GB can be sent as a document, but the receiver has to download and open it. For anything you want watched in the chat, aim for the video limit.

Questions people ask

What is the WhatsApp video size limit?

16 MB for a video message. Larger files can only go as documents, up to 2 GB, without a preview or inline playback.

Why does WhatsApp send my video as a document?

Because it is over 16 MB, or in a format WhatsApp does not treat as a video. An MP4 under 16 MB from this tool sends as a video.

Will a 16 MB video look bad?

A 30-second clip at 16 MB is over 4 Mbps, which is plenty for 1080p. A three-minute clip has to drop to 720p to fit, and still looks fine on a phone.

How long a video fits in 16 MB?

About a minute at good 1080p quality, three to four minutes at 720p, longer at 480p. The tool picks the bitrate from the length; cap the resolution yourself for long clips.

Does it work with iPhone MOV files?

Yes. MOV, MP4, WebM and MKV all go in; an MP4 comes out.

Is there a watermark?

No.
