How to Reduce Image File Size Without Losing Quality

Large images are one of the most common reasons a website feels slow. The good news is that you can usually shrink an image significantly before most people would notice any difference in quality.

Start by choosing the right format for the content — photos usually compress better as JPG or WebP, while flat graphics compress better as PNG. From there, use a quality slider rather than the maximum setting; quality around 70-85% is often visually indistinguishable from 100% but noticeably smaller in file size.

It also helps to resize images to the dimensions they'll actually be displayed at, rather than uploading a much larger original. Between choosing the right format, a sensible quality setting, and appropriate dimensions, most images can be reduced by 50% or more with no visible loss in quality.
