TinyPNG is a free online tool that intelligently compresses PNG and JPEG images while preserving visual quality. It uses a technique called quantization to selectively reduce the number of colors in an image, merging similar shades that the human eye cannot easily distinguish. This often reduces file size by 50% to 80% with no noticeable loss in perceived quality. The tool is widely used by web developers and designers to speed up page loading and reduce bandwidth costs.

The workflow is straightforward: drag and drop images onto the page, wait a few seconds, and download the compressed files. TinyPNG also offers a paid API for developers who need automated compression in their build pipelines, and a plugin for Photoshop that compresses images directly within the editor. For anyone publishing images on the web, TinyPNG is one of the simplest and most effective performance optimizations available.
