How PNG to WebP conversion works here
Your image is decoded by your own browser, drawn to a canvas, and re-encoded as WebP. Nothing is uploaded to a server, there is no queue, and no copy of your file is left anywhere after you close the tab.1. Upload your PNG image
Choose a.png file, or drag one anywhere onto this page.2. Check the WebP preview
The WebP is encoded in your browser so you can see it, and the converted size, before downloading. Move the quality slider to trade detail against file size and the preview re-encodes as you go.3. Download the WebP
Click Download WebP when the preview looks right.Why convert PNG to WebP?

• Smaller assets for apps, themes, and email templates
Good to know
WebP here is lossy, so the quality slider is a real trade. Start at the default and lower it while watching the output size; flat graphics and text tolerate far less compression than photographs.If you enjoy the site, consider joining our Patreon We will also try to do our best to create animation options of your choosing :)
