How to convert PNG to WebP
- Drop one or more PNG files into the box above (or click to browse).
- Adjust the quality slider — 85% is a great balance of size and sharpness.
- Download your WebP files individually or all at once.
Why convert PNG to WebP?
PNG is a lossless format, which makes it great for editing but heavy for the web. WebP uses modern compression that produces files 60–80% smaller at the same visual quality, while still supporting transparency. Smaller images mean faster page loads, better Google Core Web Vitals scores, and lower bandwidth bills — which is why WebP is the go-to format for websites, online stores and blogs.
Frequently asked questions
Why should I convert PNG to WebP?
WebP files are typically 60–80% smaller than equivalent PNGs, which makes web pages load faster and improves Core Web Vitals. Every modern browser supports WebP.
Does converting PNG to WebP lose quality?
At the default 85% quality the difference is invisible for most images. Slide quality up to 100% for near-lossless results, or down for the smallest possible files.
Is PNG transparency preserved in WebP?
Yes. WebP fully supports alpha transparency, so logos and graphics with transparent backgrounds convert perfectly.
Are my PNG files uploaded to a server?
No. Conversion runs entirely in your browser, so your images never leave your device.
