Introduction

Here is a quick way to capture a screenshot and save it into a file:

await Page.ScreenshotAsync(new(){    Path = "screenshot.png",});

Screenshots API accepts many parameters for image format, clip area, quality, etc. Make sure to check them out.

Full page screenshots

Full page screenshot is a screenshot of a full scrollable page, as if you had a very tall screen and the page could fit it entirely.

await Page.ScreenshotAsync(new(){    Path = "screenshot.png",    FullPage = true,});

Capture into buffer

Rather than writing into a file, you can get a buffer with the image and post-process it or pass it to a third party pixel diff facility.

var bytes = await page.ScreenshotAsync();Console.WriteLine(Convert.ToBase64String(bytes));

Element screenshot

Sometimes it is useful to take a screenshot of a single element.

await page.Locator(".header").ScreenshotAsync(new() { Path = "screenshot.png" });
