Online PNG and APNG Compressor

Compress PNG images and APNG animations to reduce file size. The compressor offers two approaches: lossless compression (OxiPNG) rewrites PNG data more efficiently, stripping unnecessary metadata and finding optimal encoding parameters with typical reductions of 10-40%. 8-bit palette quantization reduces the image to 256 colors, which can dramatically shrink file sizes (often 60-80% smaller), especially for images with many colors. Adjust the quality slider to control the palette accuracy and the dither amount to smooth color transitions. Both methods can be combined for maximum savings.

For animated APNG files, the "Drop every second frame" option provides an additional lossy size reduction by removing half the frames while keeping the animation duration roughly the same - effectively cutting the frame rate in half. This can significantly reduce file sizes for animations where ultra-smooth playback is not critical.

Optimizing images used on the web saves bandwidth, improves page load times, and contributes to better Core Web Vitals and SEO performance.
