The HiDPI (High Dots Per Inch) image setting in Webflow is used to optimize images for high-resolution displays, such as Retina screens, which have a higher pixel density than standard displays. When this setting is enabled, Webflow automatically serves images at double the resolution (2x) for devices with higher pixel densities.
This helps ensure that images look sharp and clear on these high-resolution displays, reducing the likelihood of pixelation or blurriness. However, using HiDPI images can increase the file size, so it鈥檚 a trade-off between image quality and performance (load time).
You should enable this setting when you want your images to look crisp on devices like Apple鈥檚 Retina displays, but be mindful of the file sizes to avoid slowing down your site.
