How to Capture Screenshot (Snapshot) of Web Page (Website) from url in c#

Apr 15, 2014

Here I will explain how to capture or take screenshot of web page in or how to get snapshot of website web page in using C# and VB.NET. To capture screenshot or snapshot of web page in we need to use WebBrowser control in windows forms application.


To capture web page screenshot first create new website à Right click on website à Select Add Reference à  Select System.Windows.Forms and click OK

Once we add System.Windows.Forms reference to our application then we need to write the code like as shown below

<html xmlns="">
<title>take snapshot(screenshot) of webpage in</title>
<form id="form1" runat="server">
<td><b>Enter Web Url:</b></td>
<td><asp:TextBox ID="txtweburl" runat="server" /></td>
<asp:Button ID="btnscreenshot" Text="Take Screenshot" runat="server" OnClick="btnscreenshot_click" />
<br />
<asp:Image ID="imgscreenshot" runat="server" Visible = "false" Height="500" Width="500" />
Now in code behind add the following namespaces

C# Code

using System;
using System.Drawing;
using System.IO;
using System.Threading;
using System.Windows.Forms;
After that add below code in code behind

protected void Page_Load(object sender, EventArgs e)
protected void btnscreenshot_click(object sender, EventArgs e)
Thread thread = new Thread(GenerateThumbnail);
private void GenerateThumbnail()
WebBrowser webrowse = new WebBrowser();
webrowse.ScrollBarsEnabled = false;
webrowse.AllowNavigation = true;
webrowse.Width = 1024;
webrowse.Height = 768;
webrowse.DocumentCompleted += webbrowse_DocumentCompleted;
while (webrowse.ReadyState != WebBrowserReadyState.Complete)
private void webbrowse_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
WebBrowser webrowse = sender as WebBrowser;
Bitmap bitmap = new Bitmap(webrowse.Width, webrowse.Height);
webrowse.DrawToBitmap(bitmap, webrowse.Bounds);
MemoryStream stream = new MemoryStream();
bitmap.Save(stream, System.Drawing.Imaging.ImageFormat.Jpeg);
byte[] strbytes = stream.ToArray();
imgscreenshot.Visible = true;
imgscreenshot.ImageUrl = "data:image/jpeg;base64," + Convert.ToBase64String(strbytes);


Imports System.Drawing
Imports System.IO
Imports System.Threading
Imports System.Windows.Forms
Partial Class vbcode
Inherits System.Web.UI.Page
Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
End Sub
Protected Sub btnscreenshot_click(ByVal sender As Object, ByVal e As EventArgs)
Dim thread As New Thread(AddressOf GenerateThumbnail)
End Sub
Private Sub GenerateThumbnail()
Dim webrowse As New WebBrowser()
webrowse.ScrollBarsEnabled = False
webrowse.AllowNavigation = True
webrowse.Width = 1024
webrowse.Height = 768
AddHandler webrowse.DocumentCompleted, AddressOf webbrowse_DocumentCompleted
While webrowse.ReadyState <> WebBrowserReadyState.Complete
End While
End Sub
Private Sub webbrowse_DocumentCompleted(ByVal sender As Object, ByVal e As WebBrowserDocumentCompletedEventArgs)
Dim webrowse As WebBrowser = TryCast(sender, WebBrowser)
Dim bitmap As New Bitmap(webrowse.Width, webrowse.Height)
webrowse.DrawToBitmap(bitmap, webrowse.Bounds)
Dim stream As New MemoryStream()
bitmap.Save(stream, System.Drawing.Imaging.ImageFormat.Jpeg)
Dim strbytes As Byte() = stream.ToArray()
imgscreenshot.Visible = True
imgscreenshot.ImageUrl = "data:image/jpeg;base64," & Convert.ToBase64String(strbytes)
End Sub
End Class
