When I search images on google and select copy image address from the right-click menu, the address isn't a conventional https://... one. In fact it's a massive string that begins with data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD.... What is this? Also how do I use this image to save it to a file?
The URL is a Data URL. You can save it to a file as per this explanation:
function dataURLtoFile(dataurl, filename) {
var arr = dataurl.split(','),
mime = arr[0].match(/:(.*?);/)[1],
bstr = atob(arr[1]),
n = bstr.length,
u8arr = new Uint8Array(n);
while(n--){
u8arr[n] = bstr.charCodeAt(n);
}
return new File([u8arr], filename, {type:mime});
}
//Usage example:
var file = dataURLtoFile('data:text/plain;base64,aGVsbG8gd29ybGQ=','hello.txt');
console.log(file);
