PNG Optimizer & Lossless Compressor
Compress PNG files by up to 70% without losing visual quality. Strip metadata and optimize alpha channels to speed up your website's load time.
The Ultimate Web Image Compressor
PNGs are fantastic because they support transparency and are lossless, but that makes them huge files. If your website is slow, unoptimized PNGs are usually the culprit. This tool runs a local quantization algorithm that groups similar colors and strips invisible metadata (like camera info and color profiles) to drastically reduce the file size—often cutting it in half—while leaving the image visually identical to the human eye.
