JPG to WebP converter
Turn JPG files into WebP for free. The conversion runs entirely in your browser, so your pictures are never uploaded anywhere.
How to convert JPG to WebP
- Add your JPG files. Drop one or more .jpg files on the box above, or tap it to pick them from your device.
- Let it convert. Each picture is converted to WebP in about a second, right in your browser.
- Download the WebP. Press Download next to each file. Nothing was sent to a server, so close the tab and it's gone.
What is a JPG file?
JPG (JPEG) is the most widely supported picture format in the world. It uses lossy compression tuned for photographs, so files stay small while photos look natural.
What is WebP?
WebP is Google's modern web image format. It makes files about 25 to 35% smaller than JPG at the same visual quality and supports transparency and animation.
Why convert JPG to WebP?
JPG is great for opens everywhere: every phone, browser, email client, website builder and print shop, but no transparency, and each re-save loses a little quality. WebP is the better choice for small files for websites, with transparency; keep in mind some older apps, editors and upload forms still refuse WebP.
Will I lose quality?
WebP uses lossy compression tuned so the difference is invisible at normal use. We use high-quality settings by default, and you can raise the quality slider before converting.
Private by design
Most online converters upload your file to their servers. This one doesn't: the converter itself is loaded into your browser and works offline from there, so your pictures never leave your phone or computer.
