About This Tool
Why use PNG to WebP?
Convert PNG images to WebP at quality 80, the setting most image pipelines settle on because it is where the file gets dramatically smaller and the difference is still not visible at normal viewing size. Transparency is preserved, which is what makes WebP a real replacement for PNG rather than a compromise.
For a site, this is one of the cheapest performance wins available. A page of PNG logos and screenshots converted to WebP commonly drops 60 to 80 per cent of its image weight, and image weight is usually the largest part of what a visitor downloads. Every current browser supports WebP, so there is no longer a fallback to maintain.
Key Benefits
Keeps transparency
WebP has a full alpha channel, so logos, icons and cutouts convert without needing a background colour.
Large size savings
Quality 80 typically removes most of a PNG's weight while staying visually indistinguishable at normal viewing size.
Better Core Web Vitals
Lighter images load sooner, which directly improves Largest Contentful Paint — one of the page experience signals search engines measure.

PNG to WebP FAQs
Do all browsers support WebP?
Yes. Chrome, Firefox, Edge and Safari have all supported WebP for years, so a fallback image is no longer necessary for normal web use.
Is transparency preserved?
Yes. WebP supports an alpha channel, so transparent PNGs convert without a background being added.
Is the conversion lossy?
Yes, at quality 80. That is deliberate: it is where the file gets much smaller while the difference stays invisible at normal viewing size. Keep your PNG originals for editing.
How much smaller will the file be?
Typically 60 to 80 per cent smaller than the PNG, though it depends on the image. Photographs and screenshots gain most; tiny flat icons gain least.
