Online PNG and APNG Optimizer - Lossless Compression

Compress PNG images and APNG animations to reduce file size without any loss in visual quality. The optimizer uses advanced lossless compression (OxiPNG) to rewrite PNG data more efficiently, stripping unnecessary metadata and finding optimal encoding parameters. File size reductions of 10–40% or more are common, depending on how well the image was previously optimized.

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.
