Do I need to set both width and height?

No. You can enter one side only, or both, and the server will generate the resized result from those bounds.

Which formats can I resize?

The first version accepts PNG, JPG, and WebP so the flow stays simple and stable.

Does this resize happen in the browser?

No. The file is submitted to the server action and processed on the server before the result comes back.
