# Convert PNG to WebP

PNG is lossless and often huge, especially for photos and screenshots. WebP supports transparency too, so product cut-outs, graphics and screenshots can become a fraction of the size.

**Quick answer:** To convert PNG to WebP, add the PNG files, keep 90 percent quality and press Convert to WebP. Transparent areas stay transparent. Photos saved as PNG often shrink by 80 to 90 percent; simple logos may shrink less. WebP is saved by Chrome, Edge and Firefox, not Safari. Nothing is uploaded.

## How to use it

1. Choose one or more PNG files.
2. Keep 90 percent quality for sharp edges, or lower it for photos.
3. Press Convert to WebP.
4. Download the WebP files and compare the sizes in the result.

## Transparency is kept

Unlike JPG, WebP has an alpha channel, so cut-out product photos, logos and stickers keep their see-through background. That makes PNG to WebP the natural switch for online shops and websites that currently serve large PNGs.

## How much smaller?

| PNG content | Typical saving as WebP |
| --- | --- |
| Photo saved as PNG | 80 to 90 percent |
| Screenshot with text | 50 to 80 percent; check the text stays crisp |
| Product cut-out with transparency | 60 to 85 percent |
| Small logo or icon with flat colours | Small; a compressed PNG or SVG may be as good |

The WebP made here is lossy, so it is not a pixel-perfect copy. For line art, UI and text, keep quality at 90 percent or higher, or stay with PNG and shrink it with [Compress PNG](https://sharelargefilesfree.com/tools/compress-png).

## Browser note

Chrome, Edge and Firefox can save WebP. Safari displays WebP but cannot create it; there the page falls back to PNG and tells you. Need JPG instead? Use [PNG to JPG](https://sharelargefilesfree.com/tools/png-to-jpg).

## Frequently asked questions

### Does WebP keep transparency?

Yes. Transparent and semi-transparent areas of the PNG stay transparent in the WebP.

### Is PNG to WebP lossless?

Not here: the WebP is lossy, which is what makes it so small. At 90 percent the difference is hard to see, but for pixel-exact graphics keep the PNG.

### Can I convert many PNGs at once?

Yes. Add them all and download the WebP files as a ZIP.

### Are my images uploaded?

No. The conversion happens in your browser.
