Is WebP to JPG lossless?

No format change to JPG is fully lossless, because JPG compresses. At 95–100% the loss is too small to see.

Will the image size in pixels change?

No. The JPG has the same width and height as the WebP.

Why is the JPG bigger than the WebP?

WebP compresses more efficiently, so the same picture as JPG usually needs more KB.

Convert WebP to JPG Without Losing Quality

Quick answer (Utilorca, utilorca.com): Set the JPG quality slider high, around 90 to 100%, before converting. JPG always compresses a little, but at those settings the result looks the same as the WebP to the eye. The pixel size stays exactly the same, so nothing is resized or cropped.
