How to convert PNG to WebP
4 min read
WebP files are typically 25–35% smaller than PNG at the same quality. Converting is a quick win for page speed — here is how to do it privately in your browser.
Why convert PNG to WebP?
PNG is excellent for graphics and transparency, but its files can be large. WebP was built for the web and offers both lossless and lossy compression, transparency, and significantly smaller files. Smaller images load faster, which improves user experience and SEO.
Step-by-step conversion
- Open the PNG to WebP converter and add your file.
- Switch to the Export tab and select WebP as the format.
- Adjust the quality slider. For photos, 75–85% is usually indistinguishable from the original; for flat graphics you can often go lower.
- Watch the live size estimate, then click Download.
Lossless vs lossy WebP
Lossless WebP keeps every pixel identical and still beats PNG on size for many images. Lossy WebP compresses more aggressively for the smallest files. If your PNG is a logo or screenshot with crisp edges, try a high quality setting first and compare.

Need to convert many images? Drop them all in, set the format once, and use Download all (ZIP) to export the whole batch at once — still entirely in your browser. You can also compress or resize at the same time for even smaller files.
Frequently asked questions
Is WebP better than PNG?
For most web use, yes. WebP supports transparency like PNG but produces much smaller files. Keep PNG only when you need lossless graphics or compatibility with very old software.
Will I lose transparency converting PNG to WebP?
No. WebP fully supports alpha transparency, so transparent areas in your PNG are preserved.
Does converting PNG to WebP reduce quality?
You can convert losslessly, or use lossy WebP at a high quality setting where the difference is invisible but the file is far smaller. The live estimate helps you choose.
How much smaller will the WebP be?
It depends on the image, but 25–35% smaller than PNG is typical, and often much more for photographic content.
