What WebP to JPG Does

This tool decodes each WebP file onto an in-browser canvas and re-encodes the resulting pixel data as a JPG using the browser's own JPEG encoder. Nothing is uploaded — the whole decode-and-re-encode cycle runs on your machine, which is why the tool keeps working on large batches and on files you'd rather not hand to a server. The two formats are not equivalent. WebP can be either lossy or lossless and carries a full alpha channel; JPG is always lossy and has no alpha channel at all. That difference produces two concrete effects. First, transparency cannot survive the conversion: transparent and semi-transparent pixels are composited onto a solid white background before encoding, and converting the JPG back to PNG later won't bring the transparency back, because it was discarded here. Second, if your source is a lossy WebP — which most WebP images saved from websites are — the JPG encoder compresses an image that has already been through one round of lossy compression. The two passes stack. You are not restoring detail the WebP encoder threw away, you are re-encoding what's left, and at low Quality values the artifacts from both passes can compound around sharp edges and text. Keeping Quality high is the practical way to keep the second pass close to invisible. Animated WebP is a further limitation: canvas drawing captures one static frame, so an animated WebP converts to a single still JPG and the animation is lost.
