About the PNG to WebP

WebP files are usually much smaller than PNG while still supporting transparency, which makes them a good fit for website graphics, icons and product cut-outs. This tool turns a PNG into a WebP at the quality you choose, in your browser, and keeps the transparent areas intact so the image still sits cleanly on any background.

What you can do

• Convert a PNG to WebP with a quality slider, starting at 85 percent.
• Keep transparent and semi-transparent pixels in the output.
• Watch the preview and file size change as you move the slider.
• Download the result as a .webp file with a name you choose.

When it works best

• Speeding up a web page that loads large PNG banners or illustrations.
• Shrinking transparent product photos for an online shop.
• Reducing the size of image assets bundled into a web app.

Things to know

• The PNG is processed by your browser on your device, with no upload.
• Below 100 percent quality, WebP is lossy, so fine pixel art or tiny text can soften. Raise the quality if edges look smeared.
• Almost every current browser shows WebP, but some desktop apps and older systems still cannot open it.
• If you need the file back as PNG later, use WebP to PNG.
