Converting JPG to WebP is a more modest win than converting a PNG, and it is worth understanding why before you judge the result. Your JPG has already been compressed once, and most of the easily removable redundancy is gone. WebP is simply a more efficient codec, so it stores what remains in fewer bytes.
In practice, a JPG saved at a typical camera or CMS quality drops by roughly 25-40% when moved to WebP at a visually equivalent setting. That is a genuine and worthwhile saving for a web page where images dominate the page weight, but it is not the dramatic 80% you see quoted for PNG conversions.
There is a caveat specific to this direction: you are re-encoding already-lossy data, so a small amount of additional quality is lost. At quality 80 this is invisible in normal viewing. If your source JPG was already heavily compressed and shows blocky artefacts, WebP will faithfully reproduce those artefacts rather than repair them.
If you have the original uncompressed file, converting that to WebP directly will always beat converting the JPG. Every intermediate lossy save costs a little quality that cannot be recovered.

Frequently asked questions
How much smaller is WebP than JPG?
Usually 25-40% at matched visual quality. The exact figure depends on how aggressively your JPG was compressed to begin with — a high-quality JPG has more to give than one already saved at quality 60.
Will converting lose quality?
A small amount, because the JPG is already lossy and WebP re-encodes it. At the default quality of 80 the difference is not visible at normal viewing size. Raise the slider toward 90 if you want to be conservative.
Is it better to convert or just re-compress the JPG?
Converting to WebP almost always wins. At the same file size WebP holds more detail than JPEG, so you get either a smaller file at equal quality or better quality at equal size. Re-compressing a JPG as a JPG mostly just degrades it.
Can I batch convert?
Yes — drop as many files or a whole folder as you like, then download everything as a ZIP. Processing happens locally, so there is no per-file or total size limit.
