Frequently asked questions
Are my images uploaded anywhere?
No. The conversion runs locally in your browser using the canvas API — your images never leave your device.
Does WebP keep PNG's transparency?
Yes. WebP supports a full alpha channel, so transparent areas in your PNG stay transparent in the converted file.
Why convert PNG to WebP?
WebP files are usually much smaller than PNG at equivalent quality, which speeds up page loads and saves storage — especially useful for images used on the web.
