Frequently Asked Questions

Does compressing PNG reduce quality?

No. PNG uses lossless compression, so the compression level only affects encoding efficiency, not the visual content.

What is the difference between PNG compression level and quality?

For PNG, the quality slider controls compression effort (higher = smaller file, slower). The visual output is identical at any compression level.

When should I use PNG vs WebP for the web?

Use WebP for serving images on the web (better compression). Keep PNG for source files or when software compatibility requires it.
