About the Image to WebP Converter
WebP files are usually 25 to 35 percent smaller than a JPEG of the same visual quality, and far smaller than a PNG. That matters because page speed is a ranking factor, and images are almost always the heaviest thing on a page. This converter does the work in your browser, so your photos are never uploaded to a server.
How to use it
- Choose a PNG or JPG from your device.
- Press Convert to WebP.
- Compare the original and new file sizes shown under the preview.
- Download the WebP file and use it on your site.
Common questions
Will WebP work on every browser?
Yes. Chrome, Firefox, Edge, Safari and all current mobile browsers support WebP. Support has been universal since Safari 14 in 2020, so you no longer need a JPEG fallback for ordinary websites.
Does converting reduce the quality?
Slightly, but rarely in a way anyone notices. WebP uses smarter compression than JPEG, so at the same visual quality the file is meaningfully smaller.
Are my images uploaded anywhere?
No. The conversion runs entirely inside your browser using the canvas API. Nothing leaves your device, which also means it works offline once the page has loaded.
Can I convert transparent PNGs?
Yes, WebP supports transparency, so logos and cut-out images keep their transparent background.
