How to Compress JPEG File in Asp.Net

How to Compress JPEG File in Asp.Net:-

Through this code jpeg files will be compressed without loosing the resolution. 

First you need to create 2 folders in your project.
1. UploadImages
2. CompressedImages

Code For aspx page:-

<div>

<h3>Upload File To Compress</h3>

<asp:FileUpload ID="fu_Compress" runat="server" Style="background-color: #83CF32;

border-radius: 5px; -moz-border-radius: 5px; height: 30px; color: White; -webkit-border-radius: 5px;" />

<asp:RequiredFieldValidator ID="RFVfileupload" runat="server" ToolTip="Image required."

CssClass="failureNotification" Display="Dynamic" SetFocusOnError="true" ErrorMessage="Image required." ControlToValidate="fu_Compress" ValidationGroup="sbmitbtn" ForeColor="Red"></asp:RequiredFieldValidator>

<br />

(Max size limit 5MB per file)

<asp:Label Font-Bold="true" ID="lblmsz" runat="server"></asp:Label></p>

<asp:Button ID="btnsave" runat="server" Text="Compress" Style="background-color: #83CF32;

border-radius: 5px; -moz-border-radius: 5px; height: 30px; color: White; -webkit-border-radius: 5px;"

CssClass="Button" OnClick="btnsave_Click" ValidationGroup="sbmitbtn" />

</div>

Code For aspx.cs page:-

Code:-

  private string ActualPath
{
            get { return (ViewState["ActualPath"] == null ? string.Empty : ViewState["ActualPath"].ToString()); }
            set { ViewState["ActualPath"] = value; }
        }

private string ImagePhotoPath
{
get { return (ViewState["Path"] == null ? string.Empty : ViewState["Path"].ToString()); }
set { ViewState["Path"] = value; }
}

Method for Compressing JPEG File:-

 private void CompressJpeg(double scaleFactor, Stream sourcePath, string targetPath, int width, int height, string fileName)
        {
            try
            {
                using (var image = Image.FromStream(sourcePath))
                {
                    var compImg = new Bitmap(width, height);
                    var newGraph = Graphics.FromImage(compImg);
                    newGraph.CompositingQuality = CompositingQuality.HighQuality;
                    newGraph.SmoothingMode = SmoothingMode.HighQuality;
                    newGraph.InterpolationMode = InterpolationMode.HighQualityBicubic;
                    var imageRectangle = new Rectangle(0, 0, width, height);
                    newGraph.DrawImage(image, imageRectangle);
                    compImg.Save(targetPath, image.RawFormat);
                    lblmsz.Text = "File Compressed Succesfully.";
                    lblmsz.ForeColor = Color.Green;
                   }
            }
            catch (Exception e)
            {
                lblmsz.Text = e.Message.ToString();
                lblmsz.ForeColor = Color.Red;
             }
        }

Code for Save Button:-

protected void btnsave_Click(object sender, EventArgs e)
        {
            if (Page.IsValid)
            {
           HttpFileCollection fileCollection = Request.Files;
                string notuploaded = string.Empty;
                string fileName = Path.GetFileName(fu_Compress.FileName);

                if (fu_Compress.PostedFile.ContentLength < 5242880)
                {

                    string ext4 = Path.GetExtension(fu_Compress.FileName).ToUpper();
                    string AllowedImageTypes = System.Configuration.ConfigurationManager.AppSettings["AllowedImageTypes"].ToString();
                    if (AllowedImageTypes.Contains(ext4))
                    {
                        string RelativePath = fu_Compress.FileName;
                        ActualPath = fu_Compress.FileName;
                        fu_Compress.SaveAs(Server.MapPath("~/UploadImages/" + fileName));
                        System.Drawing.Image objImage = System.Drawing.Image.FromFile(Server.MapPath("~/UploadImages/" + fileName));
                        int imgwid = objImage.Width;
                        int imghig = objImage.Height;
                        string targetPath = Server.MapPath("~/CompressedImages/" + fileName);
                        Stream strm = fu_Compress.PostedFile.InputStream;
                        var targetFile = targetPath;
                        CompressJpeg(0.5, strm, targetFile, imgwid, imghig, fileName);//Code use for without lossing image quality.

                        DateTime goodDateHolder = Convert.ToDateTime(DateTime.Now.ToShortDateString());

                    }
                    else
                    {
                        lblmsz.Text = "Only JPEG Files";
                        lblmsz.ForeColor = Color.Red;
                    }
                }
                else
                {
                    lblmsz.Text = "Max File Limit 5MB";
                    lblmsz.ForeColor = Color.Red;
                }

            }
        }
