# How to download a map screenshot as a PNG file (screenshot helper)
This example shows how to download the current map view as a PNG file. The [screenshot helper](https://docs.maptiler.com/sdk-js/api/helpers/#screenshot) is the most convenient way to save map snapshots.
Getting a file directly is a nice option that can be useful to share some debugging context with colleagues, compare multiple styles, or share your creation on social media.
Click on the _Take screenshot_ button to download a image for the current map view

npm install --save @maptiler/sdk
