PNG to JPG — Free Online Batch Converter
Convert PNG to the smaller JPG format — batch, no upload, no watermark. Transparent PNGs will be filled with a background colour before conversion, making the result ready for sharing and uploading.
Converting PNG to JPG is primarily done to reduce file size for easier sharing and uploading. Note that JPG does not support transparency: when a PNG with an alpha channel is converted to JPG, transparent areas are filled with a background colour (white by default, configurable). Conversion happens in your browser with no upload.
