Image blurriness can occur for several reasons. Two of the most common reasons are below:
Device pixel ratio (DPR) not taken into consideration
Most devices have a DPR greater than 1 and sometimes greater than 2.
When delivering images to devices with a DPR greater than 1, you'll want to proportionately increase the pixels in the image as well.
For example, in order to generate an image to be displayed on a device with a DPR of 2.0, all you need to do is to set the
dpr transformation parameter to

Resizing images leads to blurriness
Image resizing may cause some blurriness, especially when scaling the image up from a smaller original size. One potential solution for this is using the
