Compress PNG images and keep transparency

PNG compression works best on screenshots, UI images, transparent graphics, icons, and illustrations with repeated colors. The output stays PNG, so transparent backgrounds and PNG-based workflows continue to work.

Reduce PNG file size with clear quality

For PNG, Quality controls color reduction rather than JPEG-style blur. Quality 80 and above is safer for gradients, detailed artwork, and photos saved as PNG. Lower values can produce much smaller files but may add color banding.

When to use PNG compression

Use this page when a design tool, CMS, icon workflow, or transparent asset pipeline expects PNG files after compression. Photos usually compress better as JPEG or WebP, so consider the converter when file size matters more than PNG compatibility.

FAQ

Does PNG compression keep transparency?

Yes. PNG transparency is preserved. Higher Quality values are best for complex semi-transparent artwork and gradients.

Why does PNG Quality affect colors?

PNG is normally lossless, so Pic Forge reduces colors for PNG compression. Lower Quality can make files smaller but may add banding.

Should photos be saved as PNG?

Usually no. Photos normally compress better as JPEG or WebP, while PNG is better for screenshots, UI graphics, icons, and flat-color images.
