Turning JPG photos into WebP is one of the easiest ways to speed up a website. At the same visual quality a WebP photo is typically 25 to 35 percent smaller than a JPG, which cuts page weight and loading time, especially on mobile data.
Keep JPG for sending photos by email or messaging apps, for printing, and for anyone who will open the picture in older software. JPG is still the most widely supported photo format.
JPG (also written JPEG) is the most widely used format for photographs. It uses lossy compression, which keeps files small by discarding fine detail the eye is unlikely to miss. It does not support transparency or animation, and virtually every device, browser and app can open it.
More JPG conversionsWebP is an image format developed by Google. It supports lossy and lossless compression, transparency and animation, and at comparable visual quality its files are usually smaller than JPG or PNG. That is why it is popular for websites, and current versions of all major browsers can display it.

Yes. There is no sign-up and no watermark. To keep the service available for everyone there is a 95MB limit per file and a cap on how many files one connection can process in a short period.
Your upload is used only to make the converted file. Images are processed in memory; other files are written to a private temporary folder that is deleted as soon as the conversion finishes. Nothing is kept after the result has been sent back.
For images, a little, by design: the image is re-encoded at the Quality you choose (default 75%). Audio and video are re-encoded with high-quality settings; documents keep their text and layout as far as the target format allows. Converting never restores detail that is already missing from the original.
