About this converter
PNG keeps every pixel perfectly, but the files are heavy — a single screenshot can be several megabytes. WebP was built by Google exactly for this: the same image, with transparency intact, at a fraction of the size. This converter re-encodes your PNGs locally in your browser, so big batches convert in seconds with nothing uploaded.
