how to capture screenshot in html using js or jquery [duplicate]

I'm need my clients be able to capture screenshot of any page of my website using button like this:

<button>Take screenshot</button>

I tried to use html2canvas but it's doesn't work properly for me because i have iframe's in my website and it's cause some session problems.

someone have solution for this?

i looked all over google and didn't found something that's helps me much.



Web pages are not the best things to be "screenshoted", because of their nature; they can include async elements, frames or something like that, they are usually responsive etc...

For your purpose the best way is to use external api or an external service, I think is not a good idea to try doing that with JS.

You should try url2png


you can use HTML5 and JavaScript this is a sample code that worked for me.

(function (exports) {
    function urlsToAbsolute(nodeList) {
        if (!nodeList.length) {
            return [];
        var attrName = 'href';
        if (nodeList[0].__proto__ === HTMLImageElement.prototype
        || nodeList[0].__proto__ === HTMLScriptElement.prototype) {
            attrName = 'src';
        nodeList = [], function (el, i) {
            var attr = el.getAttribute(attrName);
            if (!attr) {
            var absURL = /^(https?|data):/i.test(attr);
            if (absURL) {
                return el;
            } else {
                return el;
        return nodeList;

    function screenshotPage() {
        var screenshot = document.documentElement.cloneNode(true);
        var b = document.createElement('base');
        b.href = document.location.protocol + '//' +;
        var head = screenshot.querySelector('head');
        head.insertBefore(b, head.firstChild); = 'none'; = 'hidden'; = 'none'; = 'none'; = 'none'; = 'none'; = 'none';
        screenshot.dataset.scrollX = window.scrollX;
        screenshot.dataset.scrollY = window.scrollY;
        var script = document.createElement('script');
        script.textContent = '(' + addOnPageLoad_.toString() + ')();';
        var blob = new Blob([screenshot.outerHTML], {
            type: 'text/html'
        return blob;

    function addOnPageLoad_() {
        window.addEventListener('DOMContentLoaded', function (e) {
            var scrollX = document.documentElement.dataset.scrollX || 0;
            var scrollY = document.documentElement.dataset.scrollY || 0;
            window.scrollTo(scrollX, scrollY);

    function generate() {
        window.URL = window.URL || window.webkitURL;;
    exports.screenshotPage = screenshotPage;
    exports.generate = generate;

you can find a demo here


Look at the html2canvas project. Their approach is that they create a representation of the page inside a canvas. They don't make an actual screenshot, but builds it based on the content on the page and the loaded stylesheet. It could be used on the entire body or just a specific element.

It is also really easy to use. Here is an example:

html2canvas(document.body, {
  onrendered: function(canvas) {

You can adapt it to your code relatively easy.

Take a look at their demo. Click on any of the buttons and then scroll to the bottom of the page.
