About PNG to WebP

PNG to WebP turns heavy PNG images into much lighter WebP files, often saving more than half the size. Unlike JPG, WebP can keep transparent areas, so logos, icons, product cut-outs and interface graphics stay see-through while loading faster on your website or app.

Choose the quality level: lower values give the smallest files, and higher values keep more detail in gradients and photos. The dimensions stay the same, and you can convert many files at once and download them together in one ZIP. The result list shows each new file size.

Conversion runs in your browser, so nothing is uploaded and no watermark is added. If you need a PNG back, use WebP to PNG. For photographs, JPG to WebP is the better match, and Compress Image helps with files you want to keep in the same format.

Frequently asked questions

Does WebP keep transparency?

Yes. Transparent areas of your PNG remain transparent in the WebP file.

How much smaller will the file be?

It depends on the picture, but graphics and screenshots often shrink by half or more.

Do I need an account to download?

No. You can use PNG to WebP and download your result instantly without signing up, and without giving an email address. A free PDFZOID account is optional.

Are my files uploaded to a server?

No. PNG to WebP works inside your browser, so your pictures stay on your device and are never sent to PDFZOID.
