Why compress PNG?
PNG files are lossless and uncompressed by default, making them large. Optimizing color depth and removing metadata can cut file size by over half.
Does it affect transparency?
No — transparency (alpha channel) is fully preserved during PNG compression. Perfect for logos, icons, and UI elements.
PNG vs WebP?
If you don't need PNG specifically, converting to WebP gives 30–50% better compression. Try our PNG to WebP converter for even smaller files.
