Frequently Asked Questions
How does PNG compression work?
Our tool uses libimagequant to reduce 24-bit PNG images to 8-bit palette (256 colors). This lossy color quantization achieves 60-80% compression while maintaining near-identical visual quality.
Is this the same as TinyPNG?
Yes, we use the same underlying technology (libimagequant/pngquant) as TinyPNG. The compression results are comparable.
Will PNG compression affect transparency?
No. Alpha channel transparency is preserved during compression.
How is this different from PNG optimization?
PNG optimization (like OxiPNG) only achieves 10-30% savings. Our lossy compression via color quantization achieves 60-80% — much more effective.
