How Does This Work?
This tool re-encodes your PNG image. At 100% quality, it produces a lossless PNG. At lower quality settings, it uses WebP encoding for better compression results while maintaining visual quality. All processing happens in your browser — your images are never uploaded.
Frequently Asked Questions
Will compression remove transparency?
No, PNG compression preserves the alpha channel (transparency). Your transparent backgrounds will remain intact.
What's the difference between lossless and lossy?
Lossless compression reduces file size without any quality loss. Lossy compression creates smaller files but may have slight quality differences that are usually imperceptible.
