Frequently asked questions
Is my image uploaded to a server?
No. Conversion happens entirely in your browser using the canvas API. Your image never leaves your device.
Will the WebP look worse than my PNG?
At quality 85, a photo converted to WebP normally looks the same to the eye while being much smaller. PNG transparency is kept in WebP. If you can see a difference, raise the quality to 95 or 100.
Why convert to WebP at all?
WebP files are typically 25–35% smaller than the same image as PNG or JPG, so pages load faster and use less storage. Almost all modern browsers, phones and apps support WebP.
Can I convert a JPG too?
Yes. This tool accepts PNG and JPG files (and other image types your browser can read) and outputs WebP. You can convert png to webp online free — no signup, nothing to install.
