How to send a long video on WhatsApp

WhatsApp limits the size of videos sent as media and compresses them again when they are sent. Starting from a smaller, well-encoded MP4 means faster sending and a more predictable result. Pick a size, export, then share the file from your phone or WhatsApp Web.

  1. Step 1

    Choose a video
    Pick the video you want to prepare for WhatsApp.

  2. Step 2

    Choose a size
    Select the WhatsApp limit that applies to you.

  3. Step 3

    Download the MP4
    Save the video after its final file size is verified.

What to expect

What happens
The video is re-encoded to an MP4 with H.264 video and AAC audio, the most widely playable combination. Bitrate and resolution are chosen from the size budget, and the finished file is measured before you can download it.
Good to know
WhatsApp may still compress media it receives, and limits vary by app version. Status videos are also limited in length. To send the original without recompression, share it as a document instead.

Questions

Most current versions accept videos up to about 100 MB as media. Older versions and some devices were limited to 16 MB, so that size is offered too.

WhatsApp recompresses large videos to save data. A smaller input at a sensible resolution usually survives that step with less loss.

Yes. Attach it as a document instead of a video. Documents are not recompressed, but recipients have to download them to watch.
