Frequently Asked Questions

How does PNG compression work?

PNG compression reduces file size by optimizing the encoding. At lower quality settings, the image may be converted to a lossy format for maximum compression.

Is quality preserved?

At high quality settings, the visual difference is minimal. Lower settings trade quality for smaller file sizes.
