Free WebP Converter – Convert JPEG & PNG to WebP Online
What is the Free WebP Converter
The Free WebP Converter turns JPEG and PNG images into WebP right in your browser. Everything runs client-side, so nothing gets uploaded anywhere. WebP is Google’s image format, and it cuts file size by 25–35% versus JPEG and PNG at the same visual quality.
How the converter works
Pick your JPEG or PNG images, set the quality with the slider (0–100%, default 80%), and click Convert. It all happens in your browser through the HTML5 Canvas API, so your images never reach a server.
Instant conversion in your browser
Conversions happen locally in your browser, with no server round-trip, so results show up right away.
100% private and secure
No image is sent to a server. Everything stays on your device, so your data stays private.
Batch conversion up to 20 images
Convert multiple images at once, not one at a time. Perfect for processing large collections in seconds.
Full quality control
The quality slider (0–100%) lets you balance visual quality against file size. 80% is the recommended default.
What you can do with the Free WebP Converter
