# Resize

API endpoint - `/api/2/img/[IMAGE-URL]/resize?size=[NEW-SIZE]`

## Description

**Resize** - resizes image with preserving aspect ratio and optimizes it using lossy compression. If you need the exact size then use fit operation.

## Parameters

**size** (**required**) - new size (in pixels) of the image in the format `WIDTH and xHEIGHT`. You can specify only one dimension and the second will be calculated according to the image's aspect ratio.

**dppx** (optional) - Number of dots per pixel defines the ratio between device and CSS pixels. The query parameter is a hint that enables extra optimisations for high density screens. The format is a float number in the same format as window\.devicePixelRatio.

**trim-border**(optional) - Will remove the edges of the image with the same color, if the option specified.

### Examples

* `size=200` - resize to 200 px wide preserving aspect ratio
* `size=x80` - resize to 80 px high preserving aspect ratio
* `dppx=2` - sending a hint to the API that screen has DPI=2
