The problem with raster images is that when you upscale it, it will lose its quality.

Abhijeet,

Thanks! Just one example:

New version Sketch included these artboard’s presets:

I started with iPhone 6 375x667px.

Supposably I want use embedded image for profile picture 50x50px. I prepared image 150x150 px, 72dpi and imported into Sketch. Then:

I scaled image to 50x50px for artboard 1x is for the non-retina display and my export panel will look like this:

3 images as a result: 50x50 (@ 1x.png), 100x100 (@ 2x.png), 150x150 (@ 2x.png)

It’s correct?
