# image/webp Return a copy of the image with its output format set to WebP. This tags the image — encoding happens later in `image/bytes`, `image/write`, or `image/base64`. ## Syntax

[image/webp $img ?opts]

## Parameters - `$img` — an `Image` value - `$opts` — optional map; `:quality` 0–100 (default 80). Out-of-range values are clamped, not errors. ## Examples

set img [image/open "test/fixtures/images/test.jpg"]
set out [image/webp $img %{ quality 70 }]
[image/format [image/decode [image/bytes $out]]]   # → "webp"

## Returns A new `Image` with the same pixels and dimensions but WebP as its output format and the given quality. `nil` when the argument is not a live `Image`. ## See Also `image/encode`, `image/bytes`, `image/write`, `image/base64`
