How to Compress PNG Files Online

Upload your PNG file and adjust the quality slider. The compressor re-encodes the image at your chosen quality level, significantly reducing file size while preserving transparency. All processing happens in your browser.

Why Compress PNG?

PNG files are lossless and often much larger than necessary for web use. Compressing PNGs reduces page load time, saves bandwidth, and improves Core Web Vitals scores without visible quality loss at 70-80% quality.
