Compress PNG Images Online
PNG files preserve transparency and sharp edges but can be huge — especially screenshots and UI exports. Compression reduces size while keeping alpha channels intact.
Lossless vs lossy PNG
Lossless re-encodes the PNG more efficiently — safe for logos and UI. Lossy PNG compression shrinks files more but can soften fine details. For photos inside PNG, consider converting to JPG or WebP instead.
- Logos and icons → lossless PNG or SVG
- Screenshots with text → lossless PNG
- Photos exported as PNG → convert to JPG/WebP first
Frequently Asked Questions
Does PNG compression remove transparency?
No. Our compressor keeps the alpha channel. Transparent pixels stay transparent.
When should I use WebP instead?
For web delivery when you don't need universal PNG support — WebP is often 30% smaller with transparency.
