How can I convert JPG or PNG images to WEBP to speed up a website?
Add your JPG or PNG files to Lunyce, choose the quality, then download WEBP images that are often much lighter at the same quality. Use Chrome, Edge or Firefox, since Safari can display WEBP but not create it. Images stay on your device; the conversion is free, needs no account and has no limit.
How to
- Add your JPG or PNG images.
- Choose the quality.
- Start, then download your WEBP images.
Frequently asked questions
Why does the conversion fail on iPhone or Mac?
Safari can display WEBP but cannot create it. Use Chrome, Edge or Firefox for this conversion.
Are my files uploaded to a server?
No. Processing happens entirely in your browser, on your device. No file is uploaded or stored. You can check: once the page has loaded, disconnect from the internet and the tool still works.
Is there a file size or number limit?
No. Since nothing goes through our servers, there is no quota. The only limit is your device's memory: a computer handles very large files more easily than a phone.
Is it really free?
Yes. No sign-up, no watermark added to your documents and no usage limit.
