This tool is marked offline-capable. Your inputs are used in the current browser/app session and are not required to be sent to Wiunix Tools to perform the operation.
Convert PNG and JPEG in both directions
Convert PNG to JPEG or JPEG back to PNG using browser canvas. Transparent PNG pixels are flattened onto white when JPEG is selected because JPEG has no alpha channel.
