Convert PNG to WEBP
Pick a PNG file and get WEBP in seconds — the conversion runs on your device.
Your file never leaves your device: the conversion runs inside your browser, nothing is uploaded to any server.
Frequently asked questions
Is my file uploaded?
No. The converter is downloaded to your browser once and runs there; your file stays on your device.
Is there a size limit?
Large files depend on your device's memory. Up to a few hundred megabytes works on most computers and recent phones.
Why is the first conversion slower?
The first time, your browser downloads the converter (about 30 MB). After that it is cached.
