Why use PNG to WebP for your website?
Heavy images are a common reason pages feel slow. Faster pages are nicer for visitors and help with Core Web Vitals, which Google uses as part of page experience.
WebP was designed by Google for the web. It supports transparency and animation, so it can replace both JPG and PNG on most sites. A product cutout on a transparent background, for example, does not have to stay a large PNG.
A workflow for a store or blog: export images from your editor as PNG, convert the batch here, check a few results at full size, then replace the old files. Update image links in your pages, since the endings change from .png to .webp.
Getting the best size and quality
- Photos and product shots: a quality around 80% usually looks good and saves the most space.
- Screenshots with text: stay at 90% or more, so small letters keep clean edges.
- Logos and flat icons: these are often small as PNG already, so compare sizes before you switch.
- Huge dimensions: a 5000 pixel wide image is far bigger than any screen needs. Use Resize Image first.
If a WebP looks soft, raise the slider a little and convert again. Open it in your browser at full size to judge it fairly.
Where WebP may not fit
WebP is made for web pages and is less ideal for files you send to people. Some older desktop apps, print services and upload forms still refuse it.
For those cases, keep a PNG or JPG copy. You can switch back any time with WebP to PNG or WebP to JPG. WordPress, Shopify and most modern site builders accept WebP uploads, but check your theme or platform settings if an upload is refused.
