Frequently asked questions
How much smaller is WebP than PNG?
For photos and complex graphics, WebP is often 50–90% smaller than PNG. Simple flat graphics see smaller savings, and the converter shows the exact size change for every file.
Does WebP work in all browsers?
Yes. Every modern browser, including Chrome, Safari, Firefox and Edge, displays WebP images, which is why it's recommended for faster page loads and better Core Web Vitals.
Does PNG to WebP keep transparency?
Yes. WebP supports transparency, so transparent areas in your PNG stay transparent in the WebP.
Are my files uploaded to a server?
No. Conversion runs entirely in your browser via client-side JavaScript, on your own device. Your files never touch a remote server and nothing is stored, so it's a secure, private, no-upload tool for personal photos and confidential data, and it keeps working on slow connections.
Is there a limit on file size or how many images I can convert?
No. Convert as many images as you like, as often as you like. Very large batches only depend on your device's memory, so for hundreds of high-resolution photos, convert them in a few groups.
