# Convert a tweet to WebM

WebM is the right choice when the video is going onto a web page. A ten-second WebM is routinely a tenth the size of the equivalent GIF at visibly better quality, which is why an autoplaying muted WebM has replaced the GIF on most modern sites.

## How it works

1. Paste the link to the post.
1. Keep WebM as the format and the 16:9 canvas.
1. Adjust the zoom-in motion and the 6-second length.
1. Press Render video, then download the WebM.

## Settings on this page

| Setting | Value |
| --- | --- |
| Format | WEBM |
| Aspect ratio | 16:9 |
| Theme | dim |
| Background | solid |
| Background colour | #15202b |
| Frame rate | 30 fps |
| Duration | 6s |
| Animation | zoom-in |

It is also the universal fallback here: browsers without WebCodecs cannot produce MP4, but almost all of them can record WebM from a canvas. If you choose MP4 on an older Safari, this is what you get, and the tool tells you rather than mislabelling the file.


## Questions

### Should I use WebM or MP4 on my website?

Serve both if you can, WebM first. WebM is smaller; MP4 covers the handful of players that still refuse WebM.

### Why does WebM export take as long as the video is?

WebM here is recorded from the canvas in real time rather than encoded frame by frame, so a six-second clip takes about six seconds. MP4 encodes faster than real time.

### Can I upload WebM to Instagram or TikTok?

Not reliably. Both prefer MP4. Use WebM for websites and MP4 for social platforms.
