PNG Optimizer
Quantize and re-encode PNGs for much smaller file sizes.
What it does
Reduces palette size and re-encodes a PNG using DEFLATE — typical savings are 60-90% for pixel art with no visible quality loss.
How to use it
1. Upload PNG. 2. Set Max colors (32-256). Lower = smaller file. 3. Click Optimize and download.
Pro tip
Always run the optimizer last in your export pipeline. Editing an optimized PNG further can re-introduce noise.
