How to use the JPG to WebP
- Choose your JPG files (several at once is fine).
- Adjust quality if the option is shown.
- Download the WebP files individually or as a ZIP.
What does this tool do?
WebP typically produces files 25–35% smaller than JPG at similar visual quality, which helps pages load faster. All modern browsers support it.
Conversion happens on your device, so it's fast and your pictures stay private.
Why use it?
- Faster-loading websites.
- Better Core Web Vitals scores.
- Batch convert a whole image folder.

Your files are processed entirely in your browser using built-in web technologies. They are not uploaded to our servers, and closing the page clears them from memory. There's no account to create and nothing to install.
Frequently asked questions
Are my photos uploaded?
No. Everything happens in your browser using the Canvas API. Your images never leave your device, which is why it works even on a slow connection.
Can every browser create WebP files?
Chrome, Edge and Firefox can. Safari supports viewing WebP but, in older versions, can't create it — the tool will tell you if your browser can't.
