Convert HTML to Image with C# / .NET Core

Published Jul 13, 2021

Intro

You might need to convert HTML to an image or HTML to png format for various reasons. Perhaps you are generating a snapshot or image preview of an HTML template you designed as part of your application. Maybe you are crawling websites and would like an image preview of all of them for a database. In either case, if you’re writing c# / .net core and you have been doing research, you probably came across Headless Chrome or wkhtmltoimage. Working with either is a headache. Much easier to write just a few lines of code and call it a day. You can easily convert HTML to an Image (png) with c# / .NET core within minutes using our REST API.

Convert HTML to Image with C# / .NET Core

Step 1) Open up your package manager and run the command

Install-Package Api2Pdf -Version 2.0.0

Step 2) Grab an API key from https://portal.api2pdf.com. Only takes 60 seconds.

Step 3) Use the sample code below and replace “YOUR-API-KEY” with the api key you acquired in step 2.

var a2pClient = new Api2Pdf("YOUR-API-KEY");

var request = new ChromeHtmlToImageRequest
{
    Html = "<p>Hello World</p>"
};
var apiResponse = a2pClient.Chrome.HtmlToImage(request);
Console.WriteLine(apiResponse.FileUrl);
Console.ReadLine();

And that’s it! Modify the code as you see fit. Hopefully this saves you time and makes converting HTML to images easy and painless for those writing C# / .NET core code.
