Frequently Asked Questions
How much can PNG files be compressed?
Typically 40-70% reduction depending on image complexity. Screenshots and graphics compress more than photographs.
Is PNG compression lossy or lossless?
Our compressor offers both options. At maximum quality, compression is lossless. Lower quality settings use lossy compression for even smaller files.
Will compressed PNGs look different?
At quality settings above 80%, the difference is imperceptible. Lower settings may show slight artifacts in gradients.
