Frequently Asked Questions

Why convert PNG to WebP?

WebP provides significantly smaller file sizes compared to PNG while still supporting transparency. A typical PNG can be reduced by 30-50% when converted to WebP, making it ideal for web use where loading speed matters.

Is transparency preserved?

Yes! WebP supports transparency just like PNG. Your transparent areas will be perfectly preserved during conversion.

Is the quality the same?

At the default 90% quality setting, the visual quality is nearly identical to the original PNG. For pixel-perfect lossless conversion, set the quality to 100%. Note that even at 100%, WebP's lossless mode is typically smaller than PNG.

Are my images uploaded to a server?

No. Everything runs 100% in your browser. Your images never leave your device. This makes the tool completely private and works even offline once the page is loaded.

Can I convert multiple images at once?

Yes! You can upload up to 10 images at once. They'll be automatically converted and you can download them individually or all together as a ZIP file.
