Why convert JPG to WebP for a website?

WebP is broadly supported by browsers and site builders. Whether it is smaller than the JPG depends on the image, so compare the file size shown with the result and lower the quality where the format allows it if page weight matters.

Will the WebP look the same on my site?

For most images the difference is invisible at web sizes. Use the quality control to balance sharpness against file size.

Is this JPG-to-WebP converter free?

Yes — convert and download without creating an account. Your upload is auto-deleted after conversion.

Can I adjust the WebP output quality?

Yes. Review the converted WebP result and adjust quality when that format supports it. Keep a higher setting for detail, or lower it when file size matters more.

Converting JPG photos to WebP for faster pages

This is the conversion most site owners come for. The page opens with WebP selected at quality 90 and Lossless mode off. Every current major browser displays WebP, and a lossy WebP is usually smaller than a JPG of similar visual quality, so the same photo costs visitors fewer kilobytes.

Start lower than the default. Quality 90 is cautious; for photos, try 70 to 80 and check the result against the original with the before-and-after comparison slider, looking at skies, skin and fine texture, where compression shows first. Leave Lossless mode for graphics, since on a photo it produces a much larger file. The converter keeps the JPG's pixel dimensions, so a camera photo several thousand pixels wide still needs resizing to its display width.

Phone photos are turned upright using the orientation the camera recorded, so portraits will not appear sideways on the page. For a whole gallery, Premium converts up to 60 files in one batch and Pro up to 200, with one setting for all of them and a single ZIP to download.
