Why convert JPG to WebP?
JPG (JPEG) uses lossy compression and does not support transparency, but it is supported by every device, app and website.
WebP is a modern format from Google that is typically 25–35% smaller than JPG or PNG at the same visual quality and supports transparency. WebP is the better choice for websites and blogs where fast loading and good Core Web Vitals matter.
JPG files have no transparency, so the converted WebP will look identical to the original.
Private by design
Most online converters upload your pictures to a server. This converter works entirely inside your browser using built-in image APIs, so your files never leave your device and conversion is instant even on slow connections.
When to convert JPG to WebP
A WebP at the same visual quality is typically 25–35% smaller than the JPG, so converting photo galleries and blog images saves bandwidth and loads pages faster on mobile.

Frequently asked questions
Is this JPG to WebP converter free?
Yes. It is completely free, with no sign-up, no watermark and no limit on the number of files.
Will I lose quality?
WebP uses lossy compression. At the default quality (90%) the difference is not visible to the eye. Increase the quality slider for an even closer match.
Can I convert several images at once?
Yes. Select or drop multiple files and convert them in one go, then download them individually or all together.
Should I keep the original JPG?
Yes, keep your originals. Converting between lossy formats loses a little quality each time, so always convert from the original file rather than from a converted copy.
