Frequently Asked Questions

Does PNG optimization reduce image quality?

The tool uses intelligent compression algorithms that minimize quality loss while maximizing file size reduction. You can adjust the quality slider to find your preferred balance between size and visual fidelity.

What is the maximum file size I can upload?

The tool supports PNG files up to 50MB. For larger files, consider using desktop optimization software or splitting the images.

How much file size reduction can I expect?

Typical savings range from 20% to 70% depending on the original PNG compression level and your quality settings. Images with transparency and many colors generally see greater reductions.
