Data protocol URL size limitations

Question

Is there any size limitation for \"data:\" URL scheme values? I\'m interested in limitations in popular web browsers. In other words, how long can data:image/jpg;base6

Answer 1

2017 answer is: convert data: to blob with function: dataURLtoBlob

function dataURLtoBlob(dataurl) {
    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 Blob([u8arr], {type:mime});
}

then create blob url

var temp_url = window.URL.createObjectURL(blob);

then use it in new window if you need.

var redirectWindow = window.open('');
redirectWindow.document.write('')      

works with big files in chrome/firefox 2017
