Once you’ve Base64 encoded your file, you’ll then need to add the appropriate parts that make it a data URL your browser can understand. Because of the nature of Base64, it compresses exceptionally efficiently, so a dense amount of data like that will squash down to a very small size. Where it does shine is if your Web server is compressing output before delivering it. What you don’t want to be doing is using this for massive detailed images. The trade off here is that you get instant image loading in exchange for inflating your page size slightly. Var decodedFileBytes = decodedFileBytes) Īs you can see, however, it produces a *LOT* of data.įigure 4: Beware Base64 encoding will produce large outputs String encodedText = Convert.ToBase64String(plainTextBytes) Ĭonsole.WriteLine("Plain Text : ", encodedFile) Make sure ‘program.cs’ looks as follows: using System However if you find yourself struggling, consider visiting the TechRepublic Academy!įire up Visual Studio, and start yourself a new console mode project.

Anywhere in your HTML/MVC Views that you can specify any kind of URL, you can use a data URL. What you’re looking at is something called a “base 64 encoded data URL.” This is a fairly new thing that’s been introduced in HTML5, and you can use it not only for images, but for CSS files and JavaScript. Because the images are essentially loaded with the page, the display is instantaneous when your browser loads the view.
