What changes
Both formats are lossy. Converting decodes the file and compresses it again, so it loses a little more detail on top of what the original had already lost: the result is slightly worse than the file you started with.
In our test, a 1600 × 1067 photo took 180 KB as JPG and 104 KB as WebP.
WebP supports transparency and JPG doesn’t, so there’s nothing transparent to lose: the background is already solid. What you gain is the option to remove the background later, which a JPG doesn’t allow.
WebP supports animation and JPG doesn’t, so several JPG files don’t become an animation: they would have to be joined first.
When it’s worth it
Choose WebP for: Websites, online stores and apps. Usually smaller than JPG at the same quality, with transparency.
Stay with JPG for: Photos and images for sharing.

Questions
Does converting JPG to WebP lose quality?
A little. Both formats are lossy, so the file is compressed again and loses a bit more detail.
What is the WebP format?
Google's image format from 2010, with both lossy and lossless modes, later adopted by the W3C as a web recommendation. It beats JPEG and PNG on file size and still adds transparency and animation, which is why most sites use it.
What is the JPG format?
The standard photographic image format, standardized as ISO/IEC 10918-1 in 1992 with a lossy DCT transform and no transparency. Quality is set from 0 to 100, and saving the same file again strips away a little more detail each time.
Are the files uploaded?
No. The file is opened in this tab, converted here and saved from here. There’s no account and no watermark.
How many files can be converted at once?
Up to 200 per batch and about 2 GB per file, within the memory this device has available.
