What is PNG Quantization?
PNG quantization is a process that reduces the number of distinct colors in an image. By intelligently mapping a large palette of colors to a smaller, optimized set, quantization can significantly decrease the file size of PNG images while maintaining visual quality that is often indistinguishable from the original.
Automatic vs Manual
Our tool offers two powerful modes. Automatic quantization uses advanced algorithms to find the best representative palette for your image based on your target color count. Manual mode gives you full creative control, allowing you to specify exactly which colors should be used in the final output.
Privacy & Efficiency
Process hundreds of images in seconds without ever uploading them to a server. Our browser-based quantization technology ensures your data stays on your machine, providing maximum privacy and zero network latency for a professional workflow.
