How the PNG quality setting works

What Quality does

Controls the color-quantization target of pngquant. At the top of the range PNG stays lossless; lower values allow more colors to be merged into a smaller palette so the file shrinks dramatically — especially on flat UI screenshots and icons. 75 (Balanced) works for most PNGs; drop to 60 for icons and diagrams, raise to 90+ when pixel fidelity matters.

What Is PNG Image Compression?

PNG image compression is the process of reducing the file size of a PNG image while preserving its visual quality. Effective compression can significantly improve page load times, enhance user experience, and lower server storage and bandwidth costs.

Why Should You Compress PNG Files?

  • 📌 Faster Page Load Speed: Smaller images load faster, improving Core Web Vitals scores and SEO rankings.
  • 📌 Lower Storage & Bandwidth Costs: Reduced file sizes cut server storage and CDN traffic expenses.
  • 📌 Better Mobile Experience: Smaller files load more smoothly on mobile networks, reducing user wait time.
  • 📌 Easier Sharing & Transfer: Smaller files are easier to share on social platforms and messaging apps.
