Frequently Asked Questions
Yes. PNG supports transparency and our tool preserves it. For the smallest file with transparency, consider converting to WebP.
No. All processing happens in your browser. Your image never leaves your device.
PNG compression varies by image content. Images with many colors or gradients may not compress well. Try converting to WebP for better results.
WebP offers better compression than PNG for most images. If browser compatibility is a concern, PNG is safer.
We recommend files under 20MB for best performance.
