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.

WhatsApp is a trademark of Meta, which does not sponsor or endorse Mastershot. Illustrations are simplified, and limits can change.

Your files stay on your device

Your computer does the work, so the file never has to be uploaded, and that’s also why it’s free: there’s no server time for us to pay for. You don’t need an account, and nothing you make gets a watermark.

Questions

It depends on how it's sent. As a video, WhatsApp recompresses it, and the largest it takes depends on the app: 16 MB on older versions, more on current ones. As a document, a file up to 2 GB goes through unchanged.

Compress it here to 100 MB or less and send it as a video, or attach the original as a document, which takes files up to 2 GB.

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.
