Convert JPG to WEBP
Free, in your browser, with no watermark and no signup. Both are image files; this changes how the picture is stored.
Why you have a JPG file
The same logic applied to photographs. Swapping site photos from JPG to WEBP is one of the least painful page-speed wins available, because nothing about the layout has to change.
What the conversion actually does
The photo is re-encoded as WEBP, typically landing noticeably smaller than the JPG at visually equivalent quality.
Worth knowing first
This is a lossy format converted to another lossy format, so quality drops slightly with each generation. Convert from the best original you have rather than from a JPG that has already been re-saved several times.
