Images can exist some of the heaviest components of a website, pregnant they are made upwards of more than bytes and therefore have longer for a browser to download. If you resize images for the web, you can reduce the bytes in an image to make them load faster.

If you're working with JPEGs, you'll notice that you tin can exist quite liberal with the slider. There's oftentimes no discernible departure between an image saved at 100% quality and ane saved at 60% quality, or even as low as thirty%.
