: No, our PNG compressor preserves the alpha channel (transparency) while reducing file size.
: Typically 40-70% reduction depending on the image content. Simple graphics with flat colors compress better than complex images.
: If you do not need transparency, converting to JPG will give smaller files. Use PNG compression when you need to keep the transparent background.
