Examples

Wait before taking screenshot with C# and Puppeteer

Install PuppeteerSharp

dotnet add package PuppeteerSharp

PuppeteerSharp is the .NET port of Puppeteer. BrowserFetcher.DownloadAsync() downloads a compatible Chrome on first run. The examples use C# top-level statements — put them in Program.cs of a console project (dotnet new console) and run with dotnet run.

Take a screenshot and save to file

Wait for the page to settle before taking the screenshot.

using PuppeteerSharp;

await new BrowserFetcher().DownloadAsync();
await using var browser = await Puppeteer.LaunchAsync(new LaunchOptions { Headless = true });
await using var page = await browser.NewPageAsync();

await page.GoToAsync("https://www.htmltoimage.com/demo");

// Wait for late content — here an element that appears after 2 seconds.
await page.WaitForSelectorAsync("#delayed-banner", new WaitForSelectorOptions { Visible = true });

await page.ScreenshotAsync("wait.png");

That was 12 lines of code — plus a browser to run in production

Keeping headless browsers fed, patched and scaled is a job in itself. We built Urlbox so the same screenshot is one API call: 

curl "https://api.urlbox.com/v1/YOUR_API_KEY/png?url=https://example.com"
