The JPG to PNG Converter is a free, browser-based tool that converts JPEG images to PNG format instantly. Unlike other online converters that upload your files to servers, our tool processes everything locally in your browser using the HTML5 Canvas API. This ensures 100% privacy — your images never leave your device.
