FAQ
Will compression remove transparency?
No. PNG compression preserves the alpha channel. Your transparent backgrounds stay transparent.
How much smaller will my PNG be?
Results vary by image content. Screenshots and graphics typically compress 40-60%. Photos compress less since PNG is already optimized for them.
Is PNG compression lossless?
PNG uses lossless compression by default. Our tool adjusts the compression effort level to find smaller representations without losing any pixel data.
Should I use PNG or WebP?
If you need maximum compatibility, use PNG. If you are optimizing for the web and browser support is not a concern, WebP produces even smaller files.
