Image Compressor

Image compression is one of the most effective ways to improve website performance. Large, uncompressed images are the single biggest cause of slow page load times — studies show that pages taking over 3 seconds to load lose more than half their visitors. Our free Image Compressor reduces JPG, PNG, and WebP file sizes by 40–80% while maintaining excellent visual quality, all processed locally in your browser. No files are ever uploaded to any server.

Whether you are a web developer optimizing asset delivery, a blogger reducing image attachment sizes, or a photographer preparing files for online sharing, this tool handles compression instantly. Use the quality slider to find the perfect balance between file size and visual fidelity. The before/after size display shows exactly how much you are saving. For best results, start at 80% quality — most users cannot spot the difference between 80% and 100% quality at typical screen resolutions.
