Why convert PNG to WebP

PNG files can be large, especially for photos or detailed images. WebP usually makes a much smaller file while keeping the picture clear. WebP can also stay transparent, just like PNG, so a logo or a cut-out image keeps its clear areas after converting. For websites, this is a strong pairing: PNG quality with far smaller files.

Transparency is kept

Unlike JPG, WebP supports see-through areas. So when you convert a PNG that has transparency, the clear parts stay clear. That makes WebP a good replacement for PNG on the web, where the smaller size speeds up your pages without changing how the image looks.

When PNG is still best

Keep the PNG when you need the widest possible support, such as an image going into an old program or a strict upload form. WebP is best where you control the software, like your own site. For everyday web use, WebP wins on size.

FAQ

Does WebP keep the transparent areas of my PNG?

Yes. WebP supports transparency, so clear areas stay clear after converting.

How much smaller will the WebP be?

For photos and detailed images, WebP is often far smaller than PNG. The exact saving depends on the image and the quality you pick.

Is the conversion lossy?

WebP here uses lossy compression with a quality slider. At the default it looks the same to most eyes. Lower settings trade quality for size.

Will WebP work on my website?

Yes. Every modern browser shows WebP. Only very old software may need a PNG instead.

Are my files uploaded?

No. Everything runs in your browser and nothing is saved.

What happens when I convert PNG to WebP?

The picture keeps its transparency and usually gets much smaller. WebP suits websites best; if the file must open in older software, stay with PNG.
