I solved it just use htmlToImage package

 const domEl = useRef(null);
    const downloadImage = async () => {
    const dataUrl = await htmlToImage.toPng(domEl.current);

    // download image
    const link = document.createElement('a');
    link.download = 'html-to-img.png';
    link.href = dataUrl;
    link.click();
  };
   return <button onClick={downloadImage}>Download!</button>
   <img ref={domEl} src={file} style={getImageStyle()}/>
