Frequently Asked Questions
Does compress png without losing quality reduce image quality?
At high quality settings, the difference is virtually invisible to the human eye. The tool uses smart optimization to remove metadata and redundant data before applying minimal lossy compression.
Is my image uploaded to a server?
No. All compression is done using the HTML Canvas API directly in your browser. Your images never leave your device and are never sent to any server.
What is the best format for PNG images?
PNG uses lossless compression, meaning no pixel data is lost. For further size reduction, convert PNG to WebP (25-35% smaller) or JPEG if no transparency is needed.
