Why convert JPG to WebP?
JPG and WebP are both lossy photographic formats, but WebP's compression is more efficient — it typically produces files 25–30% smaller than JPG at comparable quality. For websites that means faster loads and less bandwidth; for sharing, smaller attachments. WebP also supports transparency, though a JPG source has none to carry over. Because you're going from one lossy format to another, use a higher quality setting to avoid stacking compression artefacts. Keep the JPG only if you need maximum compatibility with very old tools.
JPG vs WebP: the format differences
JPG is lossy, universal and has no transparency. WebP is lossy or lossless, more efficient than JPG, supports transparency, and runs in every modern browser. Converting JPG → WebP shrinks the file; pick a higher quality to minimise the double-compression that happens when re-encoding one lossy format as another.
