Maintain Image Quality When Applying CSS Transform and Scale
The CSS image-rendering property helps us set an algorithm for scaling our image. The images sometimes look blurry when the transform & scale is applied. To improve the image, use the CSS image-rendering property. Let us see how to maintain the image quality.
Syntax
The syntax of CSS image-rendering property is as follows −
Selector { image-rendering: /*value*/ }
Above, the value can be −
auto − This is the default and the web browser choose the scaling algorithm automatically
smooth − Smooths out the color in your image.
high-quality − Provides higher-quality scaling
crisp-edges − Preserve the contrast and edges in your image
pixelated − The nearest-neighbor algorithm is considered if the image is scaled up.
The following examples illustrate CSS image-rendering property.
Example
In this example, we are trying to enhance the quality of an image using the smooth, pixelated, and crisp-edges values of the image-rendering properties −
#one { image-rendering: smooth; } #two { image-rendering: pixelated; } #three { image-rendering: crisp-edges; }
Let us see the example −
<!DOCTYPE html> <html> <head> <style> img { height: 200px; width: 200px; } #one { image-rendering: smooth; } #two { image-rendering: pixelated; } #three { image-rendering: crisp-edges; } </style> </head> <body> <img id="one" src="https://images.unsplash.com/photo-1610208309350-766d71494a03?crop=entropy&cs=tinysrgb&fit=crop&fm=jpg&h=128&ixlib=rb-1.2.1&q=80&w=128" /> <img id="two" src="https://images.unsplash.com/photo-1610208309350-766d71494a03?crop=entropy&cs=tinysrgb&fit=crop&fm=jpg&h=128&ixlib=rb-1.2.1&q=80&w=128" /> <img id="three" src="https://images.unsplash.com/photo-1610208309350-766d71494a03?crop=entropy&cs=tinysrgb&fit=crop&fm=jpg&h=128&ixlib=rb-1.2.1&q=80&w=128" /> </body> </html>

#one { image-rendering: pixelated; } #two { image-rendering: smooth; } #three { image-rendering: crisp-edges; } #three { image-rendering: high-quality; }
Let us see the example −
