About this tool
The Image Compressor shrinks PNG and JPEG file sizes with an adjustable quality slider and live before/after comparison. Find the sweet spot where file size drops dramatically but visual quality stays intact.
Images are usually the heaviest part of a web page. Compressing them is the single highest-impact performance optimization for most sites — smaller files mean faster loads, better Core Web Vitals, and lower bandwidth bills.
