Why WebP matters for websites

Images are usually the heaviest part of a web page. Google's PageSpeed Insights flags PNG and JPG files with the recommendation ‘Serve images in next-gen formats’ – WebP is the format it means. Every major browser has supported WebP since 2020, so there is no compatibility reason left to keep shipping large PNGs to visitors.

Quality settings for WebP

Quality 80–85 is the sweet spot for photos and rich graphics. For flat UI graphics, logos and screenshots with text, use 90–100: WebP is still far smaller than PNG at those levels and keeps edges perfectly crisp. Transparency is preserved at every quality setting.

Frequently asked questions

Does PNG to WebP keep transparency?

Yes. WebP supports alpha channels, so transparent areas stay transparent.

How much smaller will my files be?

Typically 60–80% smaller than the PNG, depending on the image and the quality setting.

Do all browsers show WebP?

Yes – Chrome, Edge, Firefox, Safari 14+, Opera and all modern mobile browsers.

Can I convert an entire folder?

Drop in up to 100 PNGs at once and download a ZIP.

Is WebP lossy or lossless?

It can be either. This tool uses lossy WebP at your chosen quality, which gives the best size savings; at quality 100 it is visually lossless.
