Generated barcodes manifest themselves as HTML tags, so they cannot be right-clicked and saved as an image. Below there's an example of the generated barcode. Is there any way within my browser (Chrome, Firefox, Safari) to convert this into an image file, or possibly an SVG (vector) file that I can use? I prefer not having to change the source code if possible.

</svg>If you want an image file, you can transform your svg into a base64 png with a canvas then download it with a download link.
document.querySelector("#download").onclick = () => {
svgToPng(document.querySelector('.barcode').outerHTML, (imgData) => {
const download = document.createElement('a');
download.href = imgData;
download.download = 'barcode.png';
download.click();
});
}
const svgToPng = (svg, callback) => {
const url = URL.createObjectURL(new Blob([svg], {
type: 'image/svg+xml'
}));
svgUrlToPng(url, (imgData) => {
callback(imgData);
URL.revokeObjectURL(url);
});
}
const svgUrlToPng = (svgUrl, callback) => {
const svgImage = document.createElement('img');
svgImage.style.position = 'absolute';
svgImage.style.top = '-9999px';
document.body.appendChild(svgImage);
svgImage.onload = function() {
const canvas = document.createElement('canvas');
canvas.width = svgImage.clientWidth;
canvas.height = svgImage.clientHeight;
const canvasCtx = canvas.getContext('2d');
canvasCtx.drawImage(svgImage, 0, 0);
const imgData = canvas.toDataURL('image/png');
callback(imgData);
document.body.removeChild(svgImage);
};
svgImage.src = svgUrl;
}
