Why convert JPG to WebP?
WebP is a modern image format built for the web: it delivers similar quality to JPG at a much smaller size. Swapping your JPGs for WebP means lighter pages, faster load times and less bandwidth — which is great for site speed and Core Web Vitals. Every modern browser supports it. The main thing to keep in mind: a few older apps and devices still can't open WebP, so if an image is meant to be downloaded and opened anywhere, JPG or PNG may be the safer choice. ConvertPixie does it instantly on your device — no app to install and nothing uploaded to a server.
Your images never leave your device
ConvertPixie reads your JPG and writes the WebP right here in your browser. Nothing is uploaded or stored — ideal for images you'd rather keep to yourself.
Frequently asked questions
Why convert JPG to WebP?
WebP is much smaller than JPG at similar quality, so your pages load faster and use less bandwidth. It's a great fit for website images and galleries.
Is WebP supported everywhere?
All modern browsers support WebP. A few older apps and devices don't, so if you need maximum compatibility for downloads, JPG or PNG can be the safer choice.
Are my images uploaded anywhere?
No. The conversion happens entirely in your browser. Your JPG images never leave your device and nothing is sent to a server.
Can I convert several JPG files at once?
Yes. Add as many JPG images as you like, convert them all, then download each WebP or grab them together as a ZIP.
Will I lose quality converting JPG to WebP?
WebP gives similar quality at a much smaller size. ConvertPixie exports at a high quality setting, so the result looks essentially identical for everyday use while the file shrinks.
