Compress PNG Images Online
Reduce PNG file sizes quickly. PNG files can be very large — our compressor reduces them by adjusting quality and dimensions. For maximum compression, you can also convert PNG to JPEG or WebP.
Common Uses for PNG Compression
- Compress PNG screenshots for documentation
- Reduce logo and graphic file sizes
- Optimize PNG assets for web performance
- Compress transparent PNG images
Frequently Asked Questions
- Can I compress PNG without losing transparency?
- If you export as PNG, transparency is preserved. However, PNG compression is less efficient than JPEG or WebP for photos. For maximum size reduction on photos, consider exporting as WebP (which also supports transparency) or JPEG.
- Why are PNG files so large?
- PNG uses lossless compression, which preserves every pixel perfectly but results in larger files compared to lossy formats like JPEG. Photos in PNG format can be 5-10x larger than the same photo as JPEG. Our tool can convert PNG to a more efficient format to dramatically reduce size.
