Frequently Asked Questions

Does this tool keep PNG format?

No. It converts the source PNG to WebP. Use a PNG optimizer when the file must remain PNG.

Is transparency preserved?

The WebP output is encoded with alpha transparency when supported by the browser.

Can I control the output quality?

Yes. The quality slider controls lossy WebP encoding; lower settings usually reduce detail and file size.

Will every PNG become smaller?

No. The output size depends on image content and encoding. The tool reports the measured result before download.

Are my images uploaded?

No. Image encoding happens locally in your browser; the converted file is downloaded to your device.
