# Convert GIF to WebM
To convert GIF to WebM, run `npx optimo animation.gif --format webm`. WebM is usually far smaller than GIF for animated content. Optimo handles format conversion and optimization in a single step.

## Command
Convert a file by targeting the output format:

```
npx optimo animation.gif --format webm

Tip: add `--dry-run` to preview changes.

## Why convert?
